boat battery help

[lil bubba]

I have done the same except I use 3-4 times a week...Now have a bigger boat with separate batteries and the starting and trolling last about the same...Both wal-mart...2 years on the troll and I'll replace .... 4 years on the start and replace....No sense in taking chances at my age....It ain't like I can get out and walk back....I'd say you doing good...
