Looking to replace my trolling motor batteries. What brand and type do you guys like ?

I have Lithium Pros 36v 60AH on my big 26ft guide boat.
Then Lithium Pros 36v 40AH on my 21ft guide boat.

I am old school and use 31 series agm with as much reserve capacity as I can get.

WalMart Everstarts are probably the best bang for the buck if you don't want to lay out a lot of cash at once. If you can swing it, go lithium's and you'll never look back.

Seriously considering lithium's but will have to change my on board charger also.

Still worth it.

I will say I juuuuuuuust had my 36v 40AH Lithium pros battery fail. It is over 15 yrs old and been in 5 boats.... great service life....probably had close to 15,000 hours of hard use and 3000- 4000 or so charge cycles. I am a full time guide and these things get hard hard use. It's been great to not have to think about it for 15 years.

Thanks guys for the info. Looks like I'll be spending more than I wanted but every thing I read says it's worth it.
