How long should a battery last?

Good question. Is the charger putting out the correct voltage or at least work fine in other batteries?
At only a year old, it may be under warranty still. I’d take a visit to where you bought it if it is.

Hey! I am NOT dead.
I won’t joke on princess bride or wife will divorce me. A trick to get low batteries trickle charging again - hook a trickle charge up to 12volt, hook jumpers up to a vehicle battery. I use my big 7.3 batts. Once the trickle reads a good charge it takes over.
Probably should throw disclaimer out here. I think you can do bad stuff beyond boil over. I forget lots of stuff and just attempt again. No malady/mishap must be ok. No telling how badly I’ve devolved good things to border line fatal lol. I used to have my tractor 12v drain down and wouldn’t recharge. I would buy a new one annually. Learned that trick and just yanked corroded wiring off headlights = problem solved. No telling how many batteries tested bad and weren’t.
Lithium like 3v for autonomous drones, etc. or other 3 cell setups you can do similar but be really careful,,,,, kerrpow. If you aren’t really non-risk adverse (depends on day) you can sort of half butt rebalance between the 3 cells but it’s sketchy at best. There are load balancers for doing that. Better way but technically you can jump lithium and rebalance close enough to get charging again. I really don’t recommend the jump method but won’t say I wouldn’t. I can’t remember and don’t have a ton of pricey lithium but recall load rebalancers weren’t stupid cheap. Probably not real expensive either.
