Hello everyone.

I’m planning to install a new trolling motor battery system and want to make sure I take proper care of it from the beginning. I’ve heard that charging habits, storage temperature, and how deeply the batteries are discharged can all affect lifespan.

My boat may sit unused for several weeks during colder months, so storage is another concern. For those using a 36v trolling motor battery, what maintenance routine has worked well for you?

Do lithium batteries require significantly different care compared with lead-acid batteries? I’d also appreciate advice on proper storage, charging frequency, and signs that a battery is beginning to lose capacity.

thanks in advance for any help
