When they worked were good. However they died and wouldn't take a recharge. Contacted the company about the warranty, and discovered they were 5 weeks past the free replacement warranty (18 months) and so they wont cover anything. No prorated replacement or anything. Definitely won't be buying anymore Duracell batteries.

Lots of juice, keeps my bass boat’s large electronics and livewell running all day long, and reliably cranks the engine to bring me back to the dock.

So far so good! These replaced the two wet cell batteries for our 24' RV. Easy to install and so far so good on performance!

Junk do not buy lasted less than a year bought 3 for my 36v trolling motor in my ZV18 with on board charging. Lucky for me Sam's gave me a full refund.

I installed 3 of these to run my 36v Minkota Ulterra on my Walleye boat, 3 years ago. I’m very impressed with the performance and value, especially compared to Optima! 5 stars! Capt Jim BALZER, DoubleJay Sportfishing

Purchased two of these batteries for my 2009 Winnebago motor home 04/2013. Now after 27 months neither battery will accept/hold a full charge. Expected a little more life for the price.

December, 2019 - Purchased 2 AGM marine 31DT batteries for 24vt minnkota trolling motor. Lightly used and regularly charged, maintained with onboard battery system. September, 2021 - Both dead and not accepting charge.

Our motorcoach came with relatively weak and poorly made Harris batteries- from the factory! Replaced them with these and have not looked back since. Holds power great, stores strong, and we are so happy we made the change!

I bought two batteries for a 24 volt trolling motor. Only used one time so far. Used the trolling motor off and on all day. Also ran a bait tank for a day and a half, alternating between the two batteries. Satisfied so far.

This is the very same battery that is sold by Marine supply stores for a little over $300. The manufacturer is the same but sold under a different brand.
