Too soon to evaluate properly, average for now

I recently purchased two of these batteries for my RV. Duracell has a good reputation but I was surprised and disappointed they were shipped with very little fluid as both were more than an inch and a half below the top of the plates. I understand they are shipped low to avoid spillage during transport and handling, but these were too low. After filling and charging they seem to be working as expected, but it's way too early to give them a proper evaluation one way or the other. Ask me again in two years. Sams click and pull system worked well.

Bad Choice

Bought this deep cycle battery to back up my sump pump. Lasted less than 17 months. Had both the sump pump charger and the battery tested. Charger was fine. Battery failed two separate tests (Sam's and the pump mfg). And, I was diligent in keeping the electrolyte at the prescibed level. In contacting Duracell, they offered no help or explanation. Seems it's always the dumb consumer's fault.

replacement battery

24V trolling motor. Replacing the dead Duracell for a new one. One of the first two lasted about a year then DOA. Was cheaper to buy another one rather than two better ones....

frustrating poor life cycle

Bought this and it was dead after two uses and placed on a battery tender to keep the battery. It was dead in 12 months, but just barely past the “1-year warranty” purchase date.

I shopped seriously before ordering these batteries for my boat online. Sam's Club had the lowest prices and the batteries were picked up at the store. Great job Sam.

Went bad after 1 yr.

Just heard some alarm and went down to the basement and find out my newer(purchased just around 1yr or so) but went bad already. I'm going to Sam's tomorrow to complaint and hopefully they can work with me.
