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.

        Pros

        • Powerful

        Cons

          Best Uses

          • Small mounting area
          • Small Outboard

          Comments about 12V AGM Batteries:

          Battery is great. Watch out for the listed size, however. I bought the AGM 12/55. The "Height" listed is actually the width as most of us would see it, with terminals facing up. I had to mount the battery on its side because of the limited height of the mounting location. Thankfully it's an AGM and I could do that! If you want a shallow battery and want it to stand upright, use the AGM 12/70 as it is lower in Height (Width? - confusing!).

          Comments about 12V AGM Batteries:

          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.
