Boat battery

[BCinerie]

I just had a battery go bad this weekend, of course 13 months old on a 12 month warranty! Second time that happened in3 years. My question is what is everyone running. Brand size etc. my boat is a 20.5 lund center console with 140 evinrude, have a dual battery set up with battery switch. What size and brand do you think ?

Thx bc

I use a plain jane West Marine dual purpose battery. About $120

History of them. Three years of reliable use for the last ten years. I replace year 4

I'm running interstates one deep cycle one combo. Too new to know how long they will last

Have good luck with Interstate batteries,both deep cycle & starting. Just replaced all 3 of mine this spring,as the old ones were 4 yrs. old.

I use odyssey batteries. They are expensive but worth it. My house battery is going on 6 years.

I actually picked up 2 new deep cycle combo (24 series) battery at autozone! Boat started right up and everything is working much better! Also got a 20% off coupon
So ended up being 170 total for both! Putting my deep,cycle I had in a storage on the boat for my backpup to my backup! It is fully charged and will throw on a charger 1 time per month or so! Thanks for the input!

Perhaps it's not a battery problem, but a charger problem or something draining the battery. Cold weather will make the problem worse, so every winter you need a new battery; works fine rest of the year?

Deka Marine Master batteries.

i dont even take my batteries out for the winter always hooked up to a battery tender multibank self diagnostic/ yes it cost 300 bucks but well worth not hauling out each year and re installing.

I just saw this post. It's a topic about which I really do know something so I weigh in. It' always surprising to me when I read about battery failure after such short periods of time. As far as the wiring goes i defer to Capt Frank but as to the batteries themselves why do people insist on using wet cell batteries on boats? At the very least the trolling motor should be hooked up separately to a deep cycle AGM sized to fit. I don' t care how much more they cost. Wouldn't you rather make an investment than commit to. A series of payments? You just can't kill these things. Forget about battery tenders. I have a 55 AH that has sat in my unheated garage for two years and still shows a full charge. I picked up two 17AH's from a friend that were both reading slightly over 6 volts. I wired them in parallel and put them on a 2 amp charge. It took 36 hours but I used them without incident for months until I sold them along with a boat.
