You need to keep deep cycle batteries at least 60% charged. To make them last. Mine last 8-10 years even in my wheelchair, camper & for my CPAP.

Ordered this online expecting to wait a couple days to get. Received email next day, it was ready to pick up. Core exchange was really easy too.

I use these as trolling motor batteries. I can get almost 3 years out of set. They have never left me in a bind on the lake and will continue to use

Good Brand and great price

At this point they have done every thing excepted !!!

Save your money. Purchased two for my boat Failed badly after 15 months

23 months and its dead. 27 series.

Been using in my pontoon boat for a few weeks with no problems. Time will tell.

Ive been purchasing Duracell Marine Batteries since 2005 and they've never let me down!!!

Excellant , powerful product. and very reasonable price.
