Deep Cycle Battery??

[Bass Hunter]

I have a 24v 6 speed OMC 42lb trolling motor on my 18 ft Triton. The trolling battery only seems to last about 2.5 to 3 hours and then gets really week. After reading my manual it said something about the deep cycle batteries should have at least 80Ah. I am not really sure what that means. I checked my batteries and they have 23Ah stamped on them. My reasoning says thats not enough. I am not familure with what Ah stands for or means. Can someone shed some light on this and give me some recomendations on a good deep cycle battery.

How old are the batteries, they might just be getting to there old age, I have the same exact trolling motor on my 19v and I can go all day on one charge no problem. I went to Autozone and got there deep cycle marine battery, and they have done great!

Ah means Amp Hours, which is the storage capacity of deep cycle batteries or in other words the maximum sustained amperage drawn from a fully charged battery over a certain amount of time to a point where the battery is dead!

Also you don't know anybody that has parts for the omc TM?

You need stronger batteries, i'd figure a 42lb 24v motor wouldn't use much battery, mine is a 46lb 12v and makes it two good trips on one charge.
