Works like a champ and cant even come close to beating the price.

Bought 2 of these Duracell group31C batteries for my RV with CAT 3126B engine. They lasted 40 month. I trickled charged when not in use. Now it is time to replace but since it is almost winter and I am not going to use the RV until next summer I'll wait until spring to purchase replacement.

I bought 2 of these trash batteries in 2023 and now both of them are bad and I found out they don't pro rate the batteries after 12 months and they don't tell you that, don't waste your money, and sam's don't care to back there batteries like everyone else.

One year warranty!!!! I wish it were longer...

Best value

Installed ok operates great no nuts for battery posts. Will see if it holds up . Put in a 48 volt golf cart
