Duracell AGM Deep Cycle Marine and RV Battery , Group Size 31

PLEASE READ THE TOP LABEL ON THESE BATTERIES. IF YOU WANT ANY AGM BATTERY TO LAST YOU NEED TO "CHARGE AND EQUALIZE" THEM A FEW TIMES A YEAR IF THEY'RE NOT PERMANENTLY CONNECTED TO AN AGM CHARGER. YOU CAN'T USE ANY OLD CHARGER. IT NEEDS TO BE AN AGM CHARGER BECAUSE ALL AGM BATTERIES, EVEN THE EXPENSIVE ONES (Optima), ARE PICKY ABOUT HOW THEY'RE CHARGED. THEY NEED TO BE CHARGED BETWEEN 13.8 VOLTS and 14.6 VOLTS. IF YOU DO THIS, THEY WILL LAST YOU MANY YEARS, SO PLEASE BUY AN AGM CHARGER IF YOU BUY AN AGM BATTERY. I LOVE THESE BATTERIES. I'm pretty sure all the people complaining don't charge and equalize their batteries eventhough it says to do so right on the top label. I love these AGM batteries. I use them to power a backup sump pumps in my basement. I use to use the regular flooded lead acid batteries but I got sick of checking the electrolyte and refilling if necessary every 6 months. I decided to give these a try and I'm so glad I did. They work great after years of use. There's no need to check electrolyte. That's a time saver in itself.

I replaced the Deka brand AGMs in my GEM cart with these Duracells. So far/so good. Dekas are over $200 more(each)The weight of these seems to be comparable to the Dekas. Heavier means better when it comes to batteries .
