About this item

Product details

Use the battery finder for help selecting the battery you need

Marine AGM batteries are specially designed for engine starting and the long, deep discharges typical of marine applications. The maintenance-free AGM design immobilizes electrolytes, making these batteries spillproof and leakproof, so they’re safe to use no matter how much your ship gets tossed. 

They are available in all popular marine sizes with abundant cranking power for quick, easy starting and all the reserve power necessary to keep your auxiliary equipment running strong. And they're backed by an 18-month free replacement guarantee*.

To have your battery installed, please call your local Tire & Battery Center to schedule an appointment.

Gel deep cycle batteries at great price

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 .
