Great for my camper

Purchased to upgrade batteries on my camper since we camp without power hookup. This battery has been great thus far.

believe the reviews, stay far away from this

11 months and only used a dozen times. Bought this as a 'house' battery for a RTT, used to power a couple of led lights, charge a couple of cellphones. now it's at 6.5 volts. not worth money.

Buy something different

Had these batteries just about 2 yrs. Used maybe a handful of times and they no longer charge with dead cells. My last set of batteries lasted 10yrs of a different brand. Bsr

Will not hold a charge

I bought two of these size 31 batteries to give me boondock power from my solar panels. These batteries, even new, did a terrible job of holding a charge. I have had them just over a year and their ability to hold a charge is decreasing.

Junk

I have gone through 6 of these batteries and every time I have to fight for a replacement because they don’t last more than 13 or 14 months. Stay away but if you do buy, at 11 months exchange it for a new one.

Do not buy

Wouldn’t hold charge after 14 months… it only has a one year replacement with nothing after that… so this battery is now just good for a core charge. That’s a hard pass for anything from the automotive center for me from now on.

Exceeded expectations

I have three of these powering a 36V Trolling motor since July 2016. They are a little thirsty having to use almost a gallon everytime topping all of them. Done it 3 times since purchased. I use my boat almost every week and spend betwwen 2-5 hours on the trolling motor. I always charge them as soon as I return. Still going strong!
