Upgrade your flooded batteries to a high quality long lasting maintenance free AGM

AGM (absorbed glass mat) batteries are great in both deep cycle and starting applications. They charge more quickly than conventional batteries, have low 3% monthly self-discharge rates and are maintenance-free—no need to add water. The spill-proof, valve-regulated design eliminates acid spills and terminal corrosion. AGM batteries are safer to operate than conventional flooded batteries, as the chance of explosion or acid spray is reduced which allow them to be installed in almost any location and any position (except upside-down).

Mastervolt AGM batteries stand apart from other AGM’s in their long lifespan, variety of configurations and adaptability. They are a great all-purpose battery. The ability to deliver high bursts of power make them suitable for starting applications. Their high tolerance for cycling make them suitable for house bank applications. The posts can be removed and configured to match existing cabling by changing the terminas (not included); eliminating additional wiring. Mastervolt AGM batteries are available in conventional group sizes with various ratings so there is one available to fit your needs. Upgrade to an AGM battery and increase the versatility of your DC system.
