Trolling motor battery

not tellin

Best, people like optima, interstate, and big mamas.

I've also personally liked Mack bully dogs and SAMS special Duracell.

All deep cycles.

I've had good luck with Interstates. I hear good things about Optimas, but their around $250 a piece.

The cheapest.

Most of the cheap batteries come out of the same plants. So you should decide based upon warranty and availability. As far as the expensive battered don't go optima they are not what they once were. Odysesy is one of the best, however sears diehard platinum are rebadged odysseys with an incredie warranty. I think it's either 7 or 8 years with something like 4 or 5 year replacement then prorate after.

Look carefully at the warranties. Not just the years total but how they handle. Replace vs prorate.

Not a fan of the Optimas, I switched to Trojan AGMs they've held up much better. Interstate is a damn fine battery also, I just put a lot of use in mine so a needed something with a longer run time.
