One year battery?

Bought this battery on 4/3/18 used it 3 times very light use no more than 50% discharge. Stored it for winter the first week of October with full charge. Got it out today 5/17/19 and it won't take a charge.

Poor product for solar storage.

Bought 6 for solar storage, after 2 years only 1 is still good, 2 are dead, and other 3 range from 25 to 75 % useful. Very poor quality, poor product.

Duracell Marine Battery

Purchased in September (Mfg. Date Aug. 2024) used intermittantly for a trolling motor for less than a month. Charged it prior to storing in a heated garage, and put on a charger (May 16th 2025) and the battery was shot! Avoid these batteries at all costs!

Junk

This battery has an18 month warranty and mine lasted 19 months. The battery has a bad cell per the technician at sams. $179 for a 19 month battery is a joke. Don’t waste your money

Duracell Deep Cell Battery -- PASS ON IT.

We bought an RV, and while relaxing outside, we noticed that the battery was venting some noxious fumes.

Old battery

These battery’s were 6 months old when I bought them. Took 1/2 gal of water to fill them.
