12V AGM Batteries

Mastervolt batteries utilize AGM (Absorbed Glass Mat) separators and advanced technology to provide maintenance-free, completely sealed battery power. Great for starting, service and deep-cycle applications, without leaks, spills and the hazards of gassing with unsealed batteries. Special one-way valves prevent pressure buildup if they’re overcharged. Can be installed in any orientation, and more compact than traditional batteries, Mastervolt AGM Batteries are built to withstand shock and vibration encountered in the marine environment. Excellent high-current-discharge behavior, accepts higher charging currents, and multiple batteries are easily linkable. Threaded M6 insert terminals. Two-year warranty.

Comments about AGM 12/270 Battery, Group Super 8D, 270Ah, 1600A CCA, 20.6"L x 9.6"W x 10.6"H, 161lb.:

These are great batteries, but heavy and hard to move.

I highly recommend them. I'm an electrical engineering and somewhat obssesive about good batteries. I'm about to buy another set of these.

I also recommend the L shaped top terminals.
