Battery question..........
I bought 3 new deep cycle group 31 batteries in May, 2016. They are about 9 months old. Recently, one of therm tested weak, so gonna get it checked. Will it be ok to replace just that one battery? I've always heard that you shouldn't replace just one battery in a 24 or 36 volt system. I sure would hate buying 2 new batteries, if they exchange this one if it's bad. Thanks.

i been running the Wally World batts for a long time. Have had a couple bad ones over the years and I just take them back. Get new battery and keep on going. No need in changing all of them. Others will argue but my system is working for 25% of the cost. Less cost=more days to fish without working

I think I would just replace the one as it should not cost you anything as Walmart marine batteries has a 2 year free replacement if not walmart batteries others give a 1 year free replacement anyway, that is if you kelp your receipt. Just replace the one and go for broke and then when they start giving you problem replace all of them then at one time. They could possibly out last a whole new set you really never know about batteries.
Be safe and good luck fishing
