Reddit reviews Battery Tender Junior Charger and Maintainer: Automatic 12V Powersports Battery Charger and Maintainer for Motorcycle, ATVs, and More - Smart 12 Volt, 750mA Battery Float Chargers - 021-0123

I feel you friend. I also went camping but did take one of those car jump all in one batteries along with a 12 volt power adapter for my machine. it had worked the previous camping trip for about three to four days just fine. But this time, it died at 1 a.m. the first night and I was awake the rest of the night. I simply cannot sleep without my cpap at this point. The rest of the trip was a misery, next night slept in the passenger seat of my Prius with the CPAP plugged and car on (on but not running). trying to sleep in a seat sucks, but the car turned itself off every hour so it was hardly any better than that first night. I believe the next night I slept in the bed of a truck with a CPAP plugged in in the truck (again, on but not running) through the little back window and it worked much better. Until it rained.

So the NEXT camping trip I got my shit together.

Get a deep marine battery. These are designed to power small things on a boat and are used to the small dribble of electricity over a long period of time. Get a battery box to place it in for safety, and a battery tender to charge it before the trip. You'll want a ring terminal harness to attach to the battery posts, and a female 12 volt adapter to plug your machine into.

The box contains everything safely with just the plugs you want sticking out the slots in the lid, but if there's small children in the camp you may want to ratchet strap it closed to be on the safe side.

I got battery and box at my local walmart. The rest from Amazon.

Battery tender to charge your battery:

And of course you'll need to get the 12 volt power adapter. Look up the model maker of your CPAP machine and Google away to see where you can find one. I looked for my manual and then I found the one that was recommended in the manual along with recommendations. Mine recommends I do not use the water chamber when using the 12 volt power adapter due to power consumption and no way am I risking the battery running out of power before the trip is over. I got the adapter from a generic CPAP supplies website.

Good luck! I'm going camping this summer I hope my setup still works!

I usually camp out of state with family and have a few nights in a house before heading home. I always bring a new face mask new filter and even a new hose if I have one as after camping the machine reeks of woodsmoke and it drives me absolutely batty.


Edited to fix oh so many typos.

PS: I will edit the links more pretty when I'm on a desktop sorry about the non pretty formatting

Or just $26 every day at Amazon

On sale and everything.

edit: more expensive ones will have higher amps I think and can work on cars or larger batteries, but for a motorcycle that one will be more than enough.

Check out this article about outdoor winter storage.

If your scooter is going to be sitting for long periods of time, use fuel stabilizer and a battery tender. Also, I would recommend treating it liberally with ACF-50, which prevents corrosion.

You might want to post in /r/chicagomotorcycles too.

At that budget level, you're going to be looking at more budget oriented radios from the likes of Baofeng, TYT, QYT, Leixn, and the other assorted Chinese manufacturers. The one you mentioned is not a bad choice, so let's run with that...

• Radio - $128.86
  
  
• 8Ah SLA battery - $17.77
  
  -or-
  
  
• 20Ah SLA battery if you don't mind the extra size and weight - $38.00
  
  
• Battery charger - $21.85
  
  
• You'll need an antenna. I'm guessing you don't have a vehicle to attach a mobile antenna too, so I'd recommend something that attaches directly to the back of the radio, like this antenna. I actually have one and it's surprisingly decent for the price. - $12.99
  
  
• You'll need a right angle PL-259 to BNC adapter to properly attach this antenna to your radio - $7.49
  
  side note: For a mag mount antenna, the Tram 1185 is a good cheap option at $21.63
  
  additional side note: Neither one of these antennas I mentioned is tri band capable, they're dual band 2m/70cm only. Tri band 2m/1.25/70cm antennas are considerably more expensive. Unless there's regular 1.25m activity in your area, you may wish to reconsider your need for having this band.
  
  Total: $188.96 or $209.19 if you choose the 20Ah battery option.
  
  Use whatever is left over for a case. A nice Pelican will probably consume the rest of your budget. Or you could go down to your local sporting goods store and browse the handgun cases there. You'll probably be able to find something good for $15-30 and have a few bucks left over. I found this 4 pistol case at my local Sportsmans Warehouse, it's cheap, reaonably well built, and is a pretty good size. I can fit a small army of handheld radios and associated paraphernalia in mine, so it should be big enough to hold a mobile rig plus battery.
  

One example of a battery tender

• battery tender, keeps the battery charged during the winter.
  
• Tinted visor for his helmet, usually those run about $15-35 depending on the helmet.
  
• Lock - Brake Lock, Chain Lock

Cheap, small, and safe...

I'd get this one: http://amzn.com/B000CITK8S

This is what I went with. I've had no issues in the 3 years I've owned it.

I use this guy. Works well.

Definitely get a battery tender for when you don't ride it for awhile.

And yeah, the connections the tender comes with look like little alligator clamps, so I can't imagine how you'd do it with a regular set of cables.

Get the battery tender, clean the carbs, turn up the choke, and go again! God my next bike will be fuel injected!

Battery Tender 021-0123 Battery Tender Junior 12V, 0.75A Battery Charger

Battery Tender Junior

This is what I use

starters ain’t too bad. could be something as easy as having a dead battery. cranking amps are a thing. take the battery out and take it to a auto shop to get load tested. that’s a decent starting place

Edit - or better yet buy a battery tender and give it a charge. If it sounds like its trying to turn over or at least "clicks" then you need a new battery.

On the small-ass batteries you're going to find on ATVs, it doesn't matter. I use a Battery Tender Jr. on my Recon 250. Works like a charm.

https://smile.amazon.com/gp/aw/d/B000CITK8S/ref=ox_sc_act_image_1?smid=ATVPDKIKX0DER&psc=1

This is what I use. Works like a charm.

Charge the battery. Then start the bike. Get a volt meter and measure the battery. Does it read 13.6/14? Then your stator is working. If its reading below 12.2/12ish then no its not.

Any cheap multi-meter like this will do.
http://www.amazon.com/Etekcity-Digital-Voltmeter-Ohmmeter-Multimeter/dp/B00B7CS3UY/ref=sr_1_7?ie=UTF8&qid=1426052117&sr=8-7&keywords=multi+meter

To make it easier to check You may as well buy a battery tender if you haven't already. Run the lead somewhere (I ran it under my passenger seat so I can plug in a USB adapter to charge my phone while I ride. But then you can meter off that in a pinch also. Not to mention it will slowly trickle charge you battery (It won't be fast by any means, but I've done it myself after this past winter, as my shed has no close by power and I didn't have time to bring my battery inside)
http://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S/ref=sr_1_1?s=automotive&ie=UTF8&qid=1426052180&sr=1-1&keywords=battery+tender


If its showing good when running you have a power draw somewhere. keep the meter connected while the bike is off. then pull one fuse at a time until it appears the load goes away(aka the voltage stays the same for a while without it draining down. Especially if its dead in 4 minutes you should be able to see it quickly). You may have a short in your lights. That's normally where I would expect it.

when you buy a battery tender it will come with a lead for connecting to the battery, as well as a lead that has battery clamps/clips on it for temporary charging.

this "lead" has two wires on one end and a fitting like the USB adapter in /u/afeagle1021's post (except it is the MIRROR IMAGE of that fitting). The two wires will go on your battery terminals (aka posts) via loops installed on their ends that go around the battery terminal screws, where you bike's electrical system makes it's contact with the battery.

there is an indicator for polarity on at least one of the wires, make sure it is attached to the corresponding battery terminal. then you plug your bike into the tender overnight and plug the usb adapter in when you need to power your phone when you are riding.

you might need to get creative about how you run your usb cable if you want it secured and out of the way.

I have them on both of my bikes. The plug just dangles out anywhere it won't get in the way. Over the winter I rotate each bike every few days.

In your case you could leave it there and forget about it, or take it off and put it back on every once in a while.

But this one would probably also do the trick:

https://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S/

Should be able to find them at your local auto parts store, or even Walmart or someplace like that.

The tender and a cigarette lighter attachement

• Sena headset. Bluetooth connection to you phone for directions, music and phone (be careful with the last)
  
• tank bag
  
• motorcycle cover - lightening deal for next 30mins
  
• battery tender & quick connector
  
• box of earplugs

Geometry fixes: Move the clipons so they're in the same position on both sides. Also, you can loosen the fork tube clamps some and wiggle them around some, this should cut down on any tweaked geometry they might have. Tighten them after you're done.

The wire: That's a trickle charger with an SAE connection. You can hook up one of these so you can charge it when you're not riding. It's super nice, easy to disconnect plug.

Motorcycle battery chargers are relatively inexpensive (say, on Amazon for instance). It's definitely a worthwhile investment, especially if you're going to make a habit of leaving your scooter alone for extended periods.

if you look on amazon you can get a battery tender for fairly cheap. With my bike I plug it in when I put it in storage and unplug it when I'm ready to ride. I don't do anything else to the bike to winterize except change the oil in the spring.
Edit: Here's the tender I bought, it's 25 bucks...(https://smile.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S/ref=lp_15707061_1_2?s=automotive&ie=UTF8&qid=1480528572&sr=1-2)

There's something wrong with your battery if it died after a single cold night. I've had multiple types of batteries over the years, all of which worked fine on cold mornings if they were properly charged.

Start with getting a battery tender to keep the battery topped off. If it still dies, then start looking at a replacement battery.

Here is my secret list shhhhhh... It's not cheap options that's for sure but I like being comfortable I guess, and it's stuff that will last for years of festival fun!

1. A deep cell marine battery: Available at any auto parts store for about $120. You can then buy a cheap cigarette lighter hook up and intall it onto the battery. Then get yourself a decent 200watt power inverter, about $30. Then you can get some decent sounding speakers that plug in or a bluetooth one. Then you can charge your phone, power the speakers, or charge the bluetooth. With these speakers the battery will last 16 hours! This will also prevent you from ever messing with your car stereo or battery for any reason. Then you can just recharge it with this for next year.
   
   
2. Blackstone's The Dash Portable Gas Grill and Griddle Combo is a great grill to cook every meal you would ever need.
   
   
3. Not to get controversial but these and these have always done me right.
   
   
4. Then this and this will leave you fealing like a million bucks or like someone in GL!

That one is kind of weird. It looks like you need to install that whole thing and then pull the power cord out of the car and plug it into a wall? That is weird.

I would use this instead. https://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S/ref=sr_1_4?s=automotive&ie=UTF8&qid=1481806706&sr=1-4&keywords=battery+tender

It's a smart charger, from a USA company made in USA, and when you don't need it you put it away. I have three of them. One for my classic car, and one for each of my motorcycles.

Add in this https://www.amazon.com/Battery-Tender-081-0069-6-Terminal-Disconnect/dp/B000NCOKZQ/ref=pd_bxgy_263_img_2?_encoding=UTF8&psc=1&refRID=S7TZQJ2BZZ3NWG4KS2KV

You connect this part to the battery terminals and leave them there. When you want to plug it in, you just connect the cords from the tender to this. Plug and play. I also use this on my motorcycles. My car I just use the standard connection clamps that come with the tender.

Cheap, USA made, and works. Read the reviews.

Or buy one from amazon for less with free shipping

I would say for the winter time a battery tender (if you live in a state with heavy winters) this one comes in right at $25 http://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S

The optima suggestion isn't going to solve the battery drain issue. Yes, it's a heavier duty battery. But if you keep pouring out 1/2 cup of water out of a jug and only replace it with 1/3 cup of water, you'll eventually run out of water.

Really needs to do a battery tender and get in the habit of plugging it in when they get home. A setup like this would be a good idea. http://s279.photobucket.com/user/NotMoneyGuy/media/IMG_3749_zps1edf0d2c.jpg.html

Have a quick disconnect say dangle through the grill of the car and plug the charger in nightly.

Edit: I like the Battery Tender brand myself.

There are stupidly simple, just plug/connect them to the battery and they're automatic.

A wall wart is where the transformer is built into the plug, usually a black cube about 2" with the dc wire coming off of it. The idea would be to have the AC to DC happen at the end of the AC line.

You can always use a bigger wire than required to carry current, the length might be an issue but the currents are so low so it wouldn't be a concern esp. with the bigger wire, as long as you can make the connectors work.

Here are the connectors I was picturing. I use them for my RC batteries. You can clip the red and black together. https://www.amazon.com/Anderson-Power-Products-Silver-Contacts/dp/B00BN0WMA2/ref=pd_cp_23_4?_encoding=UTF8&pd_rd_i=B00BN0WMA2&pd_rd_r=2MKMXG57SB6NNP5BP3QG&pd_rd_w=HMJVM&pd_rd_wg=PTBBq&psc=1&refRID=2MKMXG57SB6NNP5BP3QG

Well the cheapest option is just to drive the car, like I said before. You can buy a charger in the $50 range at Walmart/Amazon or any of these kinds of places. They're handy to have one around. Something like this: Schumacher.

I also like these small ones, which are basically slow chargers that can be left on indefinitely. Theyre good for when you have a car in storage for months, you just plug this in and leave it on. They are also capable of recharging your battery but itll take about 24 hours: battery tender.

Battery Tender Jr. Or any of the other Battery Tender Chargers.

I think that /u/rld14 pretty much covered it. But there are a few things I would add. Some of these may not apply to you, but this thread could be useful to others.

• Put the battery on a Battery Tender. You can do this in the storage unit if there is a power outlet (unlikely), or you can take the battery home and hook it up there.
  
  
• Add a fuel conditioner like STA-BIL to prevent the ethanol in the fuel from absorbing water. This should be done in addition to filling up the tank completely.
  
  
• If you don't know what kind of washer fluid was used, make sure to drain the washer tank. The previous owner may have used a summer blend that is not freeze resistant.
  
  
• Check the coolant/anti-freeze with a coolant tester If your coolant is old or too dilute it could freeze in the block during storage. That would be a nasty surprise come spring!

To hold the phone, get a RAM mount.

To charge the phone, you need this adapter and an SAE cable running from your battery (The cable with the round terminals in this kit).

I've seen some touring bikes with cup holders but a Camelbak/water bladder would probably be easier to use while riding.

> Also hook up a trickle charger to your battery (these are much better than battery blankets, and not that expensive).

Second that. I want to get this for my wife's car: http://www.amazon.com/dp/B000CITK8S

For etiquette, I keep just about everything to a quick wave or beep-beep at most. If I happen to see some others, I usually just fall in line with them as far as our paths are the same. I ride in the back of the group and keep about the same amount of space the rest of the group has. If they ride side to side, I get as close as I feel comfortable (and that isn't side by side lol). If they're staggered, I stay staggered too. Stop lights are different. Pull right up next to them and give them a quick head nod or maybe a compliment lol

they're called 'battery tenders'. Amazon Link

If you have a standard/stock battery, the standard Battery Tender will do. Just get the $30-ish dollar name brand one. You have a Panigale. "cheaper" is not in your vocabulary anymore. :)

If you have some kind of ultralight Lithium battery, you might need something different.

Take a good long highway cruise to burn off moisture build up in oils.

Pro Tip: a battery maintainer is better for your vehicle (especially the engine) than starting and idling to charge the battery.

It's not going to be the most efficient setup, but it can work. Basically, the biggest loss will be charging the batteries. Think of it like this - the generator is a gas engine spinning a motor that generates dc power. That power is converted to house current (ac) in order to let you plug in to the generator. A battery charger then converts that back to dc and charges the battery - so a portion of the power is lost in both conversions. If the goal is just charging batteries, a motor and an alternator generally cover that purpose better than a full generator.

All that said - your 800w genny, plus a trickle charger, plus a battery, plus an inverter will work out for your as well. The trickle charger works with whatever power the generator has available to charge the battery, and when you're using the power at night from the battery you'll need an inverter to run lights/gear off of the battery.

You'll probably want to charge the bikes directly from the generator too. If they use a 12v battery then you can charge it with the same setup. Charging one battery at a time, and needing several hours to charge each means you'll need to run the generator quite a bit during the day. Bring extra oil, make sure you know how much gas it consumes while running, and be safe with it. Make sure oil/gas don't get on the playa!

I would highly recommend getting something with higher wattage. 800 running is very low. I'd also recommend getting 12v lighting/gear so that an inverter is not necessary. Running 12v lights directly from the battery at night will be much more efficient than using an inverter, because you eliminate the conversion process. The inverter is the most likely piece to malfunction out there due to heat or dust so not needing one at all definitely is preferable.

I'm not sure about the mod but I've heard that these little batteries don't like sitting for a few weeks/months. I'd swap it out with a new one and then put it on a battery tender if you are going to not ride it for an extended period of time.

https://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S

That one?

Pretty much any normal 12V battery charger/tender, including the one you linked to, will work fine.

I wouldn't pay more than $25 to $30 for one. The Battery Tender Jr. puts out less current than the 5A model you linked to but will do just as good a job of maintaining the battery during storage, for about 1/3 the cost.

I'm a big fan of the old standby. Deltran Battery Tender. They make a nice small one that Amazon sells for about $25. Park the bike, plug it in, and you are good to go until the next time you ride. sauce

As others have said: don't skip the battery tender. Get something like this and leave it plugged in all winter. This will keep your battery in good shape.

Don't do this, and there's a good chance come spring that battery won't hold a charge as well (or at all) anymore.

On or off the bike doesn't matter.

Don't buy from common-motor. They're terribly overpriced because they pretend they have exclusive items. You probably want a Motobatt MB12U depending on your bike. As far as tenders, amazon has them for under $20. https://www.amazon.com/gp/product/B000CITK8S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

> leave the multimeter on it and read it while you activate the starter.

It drops to 5 volts when I hit the starter, so it looks like my battery (11 Amp-Hour) partially drained over the winter. I just ordered this 12v/0.75amp tender. How long do you think it should take to recharge?

$67 for a charger?! Screw that. The battery seems ok, 120 for a 65Ah is alright, I think mine was like 90 for 75Ah though. Get something like this: http://www.amazon.com/gp/aw/d/B000CITK8S/ref=mp_s_a_1_1?qid=1462148457&sr=8-1&pi=SY200_QL40&keywords=battery+tender+jr&dpPl=1&dpID=51BIMpwea9L&ref=plSrch

Btw, will you ever do multi night use? If so, you may want to consider a larger capacity, like 100+ Ah.

I used this guy here.

Alright thanks. I'll look into buying a trickle charger. Any reason jump starting with a car wouldn't work?

This charger from Amazon decent? I know it's 12V, just didn't know if 750 mA was enough. Does show good for lawn mowers though.

yeah that what i was going to reccommend. So if my math is correct (probably not). to run that stereo for 3 hours you would need a 9 amp batter at 12 volts. So to not destroy the battery lets round that up to 27-45 would be better. Then you would only need a small inverter and charger.

~$100

Chargers are not expensive. This one is all of $25 (https://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S) if you have a lead-acid battery. The lithium jobber is prolly not much more. They are TOTALLY worth it. I hook-up my bike to one every night.

Three forevers ago, when I was a broke student, I still saved-up to buy one. A $25 charger v. a $60 battery (at the time) is an easy equation.

This is the battery tender I've been looking at: http://www.amazon.com/dp/B000CITK8S/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=EXKXHMLCA8JE&coliid=I2UXII4LHH0O1Y

I did find an excellent vid on YouTube on how to change the oil and it looks super easy. http://www.youtube.com/watch?v=zNQ3myoYxdM&list=PLIr1thQ8KKEFR2x8aoMyVpqePp5O3Lhbf&index=3

If I opt to start up the scoot every few weeks, do I need to do the battery tender, too?

Again, thank you.

Anything wrong with the Battery Tender Jr? Battery Tender 12 Volt Junior Automatic Battery Charger https://www.amazon.com/dp/B000CITK8S/

Follow-up I guess, I have a battery tender/charger for my motorcycle, like this. Would this be able to charge that battery? I want to say yes, but battery charging has always been something of a mystery to me

EDIT: actually, this battery may not be chargeable

Took a voltmeter to it, it's reading 13.98 volts so I dont think it's needing charging

Right on! Lots of scooters have an AC/DC eletrical system. The basic things, like the igntion, headlight and taillight run on alternating current directly from the stator. "Extras" like turn signals and brake light run off direct current from the battery, and a small portion of the AC from the stator is converted to DC by the rectifier to charge the battery.
____
With the scooter off:
Good, charged battery will read 12.6 to 12.8 volts across the battery terminals.

A "flat" battery will read 12 volts and probably not crank the bike.

A battery with less than 10 volts is likely dead, deceased, never to work again.
____
With the scooter running, and good charged battery installed:
Voltage across the battery terminals should be 13 to 15 volts.
You might have to rev the bike a little to see it charging like that.
____
Every time you crank the bike, it takes 10 minutes or more of riding to charge the battery back up. Sometimes scooters charge so little on their own, they can never catch up.

If you keep recharging your booster pack and hooking it up, it may eventually "leak" enough voltage into the scooter battery to get it to a point where the scooter can finish charging it.

Otherwise, I recommend this charger: http://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S It turns itself on and off automatically, adjusting the current as necessary, so it can be left plugged in any time you come home.

It's very easy to do.

1. hook up the trickle charger to the main battery
   
2. spend $24 on a second charger for the other one
   
   If you start hooking multiple batteries together you have a very good chance of ending up with a fried charger, battery, or both. You can buy chargers with leads for more than one battery, but they are significantly more expensive than just buying one for each for some reason.

on amazon

The NCY CDI is a like a new computer brain for your Ruckus and removes the stock rev limiter. Allows you to push the rpms past the factory limitation. I don't know much about it other than that. I'll let others with more experience chime in. They're ~$100. I'd ask if he still has the OEM.

Trickle charger just keeps your battery charged when not in use. If you don't use the ruckus daily, your battery can deplete and then won't start with the electronic ignition (same thing happens to riding lawn mowers). A battery tender costs ~$25.

looks like always removed the front plastic and installed some pegs.

mileage seems about right for the age. Price seems high to me but it's heavily dependent on your market.

Is this what you're talking about? If so, then way cheaper.

https://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S/ref=sr_1_4?keywords=battery+tender&qid=1571235934&refinements=p_85%3A2470955011&rnid=2470954011&rps=1&sr=8-4

I have a short commute. It's like 8 minutes.

I just had this happen on my KTM 690. Turn the bike on, but no fuel pump sound when restarting from hot. It would also happen when the bike was sitting in the hot sun. You should get a new fuel pump. I bought the CA cycleworks pump that is superior to the OEM POS. Here it is for your bike My bike runs waaaay better now. Pulls harder and smoother all around, not to mention it doesnt have a problem starting anymore.

Also get this battery tender if you want one, but thats not your problem.

I have one of these that I could get this fella to connect to. Should be good enough plus it's easy to get the bike's battery charged up if you don't ride for a few weeks.

This is the one I have: https://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S

I think I got it off Revzilla when they had a sale.

Six to ten months isn't a terribly long time.

Top off the fuel tank. Make sure the tires are inflated well (to near the maximum specified on the sidewalls). No need to worry about flat spots on modern tires in a year's storage.. Then your best bet is to put the battery on a battery tender:

https://smile.amazon.com/Battery-Tender-021-0123-lightweight-automatic/dp/B000CITK8S/ref=sr_1_1?ie=UTF8&qid=1500037320&sr=8-1&keywords=battery+tender+jr

If you don't have access to power where it's parked and have someone that can look after it, you could do a solar float charger (someone will have to keep the snow off of it if it is going to work).

You can also take the battery out and put it on a float charger inside, but that's the least convenient option if there's a chance anybody might need the car.

Make sure you do not store it with the parking brake on. The rear pads will rust/fuse to the rotors and it can be a huge pain to free them up.

To do what? Charge the battery or jump start it? Yes it is, on the 12v setting.

To keep it topped off over winter? No, it is absolutely the wrong thing to do.
You don't want a charger or a trickle charger for that purpose.
You need a battery tender for that purpose.
I have several of these and they work well to maintain the batteries over the winter or long periods of not using them:

They also sell them as a package at most battery stores. I can't tell by the description if the tender includes the adapter as well.

Every time you get home plug it in and leave it plugged in.

First try buying one of these. I leave it charging overnight maybe once a week in the winter and never had any issues.

It's the easiest way to trickle charge, and they and can be had around 15-20 lots of places, $24 with prime shipping is pretty solid, but shop around, you may find one locally.

I bought this one on Amazon

Battery Tender Jr.! I leave my KTM on trickle with this little thing and it's fantastic.

Here is an amazon link for you, although keep in mind it's amazon.ca - https://www.amazon.ca/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S/ref=sr_1_1?ie=UTF8&qid=1487196980&sr=8-1&keywords=battery+tender+jr

I use this to keep my vehicle's battery fresh:

It's all automatic, there isn't anything to adjust and you could keep it on your battery indefinitely.

Is this it?

[This] (http://www.amazon.com/gp/product/B00JUI7VW8/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) and [this (better of the two I have installed, if I had to choose)] (http://www.amazon.com/gp/product/B00HQMCSWS/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1) are what I have installed. I have the second item on each of my two bikes, the first is only on my V-Strom because I keep adding electrical farkles and wanted a volt meter.

Looks like the second item is listed as unavailable, at least from that seller. I will say that the second item's rubber cover is more confidence inspiring than the first. The second one also gives you the option of mounting it to your handlebars or taking the bracket off and panel-mounting it. Nice long cord, sturdy construction, comes with a mid-line tap so you can tap the + line of something that's switched so the thing turns off with the key. Don't do what I did on my SV and tap your headlight, because when you switch to the high beam you'll lose your charger. Or, do it if you have a shitty charging system, because you'll want those watts back when you're switching to high beam. Tail light is better option as the line goes live with the key and stays that way always.

If I didn't have a nice place to mount the first item, I'd probably hate it, and it also requires that you wire the thing yourself. The good thing is for a rather decent price you get a nice little volt meter for your bike's battery that's fairly accurate.

The simplest solution, especially if you already have a SAE (the battery tender plug) installed, is to get this little item, made by Battery Tender. Cheap, easy, plug and play. In fact, I just noticed it's now on Prime, so I ordered one for my gf's bike (thanks for getting me to look it up again with your question).

If you don't have a battery tender hookup installed already, well, you should get one. [Here's another handy link] (http://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S/ref=sr_1_1?ie=UTF8&qid=1411160513&sr=8-1&keywords=battery+tender+jr) to the quite reasonably priced Battery Tender JR which makes a great trickle charger for your bike, comes with the plug (edit, for clarity it doesn't come with the USB plug but the thing you need to use the battery tender or the USB), and little jumper cables to stick under your seat.

I haven't tried. Mine gets driven even less than that but I keep it plugged in to one of these:

Just make sure your bike is a 12V system. It most likely is.

put the battery on a trickle charger.. that is really it. or start it every week.

Glad I could help! For future reference you should buy a Battery Tender and hook it up if the bike won't be used for extended periods of time (over 2-3 weeks).

Very informative, thank you. Would a battery tender https://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S?ie=UTF8&redirect=true fully charge the battery or would I have to opt for normal battery charger.

You can get these at pretty much any hardware or autoparts store. They aren't for recharging a dead battery but they will keep it topped up during the off season. I would also recommend getting some terminal protective spray to help limit terminal corrosion.

I am not seeing how this is any better or cheaper then just getting a second tender. If you want a project they have at it, but the simple solution is a second tender.

Battery tender JR on amazon is probably the most common and highest rated battery tender available.

This and the clamps come with the Battery Tender I bought. I have the connector on at all time and tucked under the pillion seat. You can also get cig and usb connector for it too.
