Fits together to make 1 small unitEasy to use and storeCleans battery terminal and post better that a wire brush
My rule is to start cheap. Go to your local auto parts store and pick up a battery terminal cleaning kit. They are cheap. Start there. They look like this. Make sure your terminals are tight too.
Also, as stated by another user, you may need a new alternator. But check your belt first, it may be slipping or lose. Start with the lest expensive possibilities. Check Battery doesn't necessarily mean you need a new battery, or anything else. Like a check engine light can simply be a loose or bad gas cap.

You have a corroded battery terminal. Remove the connectors (don't short the positive to ground), clean the connectors and terminals, and reconnect everything. Any auto parts store will sell a wire battery cleaner brush specifically for this purpose for about $5. It will be a handy thing to have.
