95% of the time when a consumer device talks about "lithium AA" they mean L91 primaries. These are 1.5 volts and not rechargeable.
There are li-ion the size of an AA and these are called 14500 cells. However at 3.6V they will probably destroy the collar.
If you want to use rechargeable batteries, try Eneloop NiMH AA.
For batteries, get Energizer Ultimate Lithiums (non-rechargable, won't leak).
Primary (disposable) Lithium batteries - the 1.7V Li-FeS2 ones - are rated for more than 15 years in storage these days. Definitely a good choice for emergency kits.
I'm essentially making a bug out bag, and want a decent headlamp in there. I'll likely also take this light out for other purposes as needed if need be (hiking, camping, car breaks down, etc).
The AA requirement stems from the idealism of having the same set of batteries for all of my equipment, where possible. I have a HAM radio, and a few other electronics that will already run on AA.
Edit: Also, I seem to like the Energizer Ultimate for long term all weather conditions storage
> This, of course, assumes that such a situation is possible, which it isn't, but the point stands. These companies are competing against each other, and improving their product (or how it is seen) is how they "win", and make more money.
Where then, does all the planned obsolecence we observe all the time come from? Take printer cartridges and printers, for example. Most cartridges are still overpriced and come with a chip that tells them to stop working. Here you have an example where a superior product already existed but was downgraded by the manufacturer. By the time the public caught on, it was too late. Because everyone does it, printers and printer accessories are currently on a race to the bottom in terms of a durable product.
In fact, batteries are another great example. Did you know most rechargeable shavers still have NiMH batteries in them, you know, the shitty ones that drain quickly, have a memory, and deteriorate quickly over time? Why is this even a problem when Lithium Ion batteries are super cheap and all over the place? Because the company is trying to make a product that fails eventually. Go to the store right now and take a look at those shavers. They're almost all 'rechargeable'. And no, they won't work when plugged in. They need to recharge, then they'll work. Otherwise you'd be able to use them when the battery dies, which is unacceptable.
And let's talk about batteries in general. Energizer actually does sell a rechargeable battery, but I'll give you two guesses as to whether they are lithium ion (long lasting, no memory) or not. Nope. They are NiMH and will deteriorate far faster than their lithium counterparts. And it's not because Energizer can't make lithium ion batteries because they totally do. But those can't be recharged, even though every last cell phone in the world proves that it's cheap and easy to do so.
So there you have it. That better battery actually exists, and the big battery companies are deliberately suppressing it via their own market saturation. That looks exactly like OP's criticism to me.
In addition, i was planning to use this as a power supply https://www.aliexpress.com/item/NCH6100HV-High-Voltage-DC-Power-Supply-Module-For-Nixie-Tube-Glow-Tube-Magic-Eye/32697870152.html?spm=2114.01010208.3.108.vZwTcL&ws_ab_test=searchweb0_0,searchweb201602_5_10065_10068_10000009_10084_10000025_10083_10000029_10080_10082_10081_10000028_10110_10111_10112_10060_10113_10062_10114_10056_503_10055_10054_10059_10099_501_10078_10079_10000022_10000012_10103_10073_10102_10000015_10096_10000018_10000019_10052_10053_10107_10050_10106_10051-501_503,searchweb201603_1,afswitch_5,single_sort_2_default&btsid=01248acb-17a1-4726-9719-91c4e298ac25 and this as a battery https://www.amazon.com/Energizer-L91BP-8-Ultimate-Lithium-Batteries/dp/B0000DC4EL/ref=sr_1_1_s_it?s=hpc&ie=UTF8&qid=1484880138&sr=1-1&keywords=lithium%2Baa%2Bbatteries&th=1
