The Vmaxtanks MR137 AGM Battery 120AH Marine Battery - powerboat pontoon Boat ideal for 55lb thrust -110lb thrust Minn Kota, Newport Vessels, Cobra, Sevylor and other trolling motors - BCI group 31.

This Heavy Duty 12V AGM Deep Cycle Battery has a Float Service Life span of 8 to 10 years.

Electrolyte Suspension system VMAX tanks utilize an electrolyte suspension system consisting AGM (Absorbed Glass Matt) of a high porosity that totally absorb and contain the electrolyte.

No silica gels or any other contaminants are used.

Theb  VMAX MR137's heavy duty lead tin alloys provide an extra margin of performance and service life in either float or cyclic applications, even after repeated over discharges.

The Vmaxtanks MR137 is a Maintenance Free Operation and there is no need to check specific gravity of the electrolyte or add water to VMAX tanks during float service life.

The heart of the VMAX MR137 is the unique physical and chemical structure of its plates.

The special treatment and manufacturing process the VMAX MR137 undergo gains them unique reliability, strength and high performance far exceeding those of other Pb-Ca plates used in similar looking products.

Using specially designed Absorbed Glass Matt (AGM) between the VMAX plates, adds to it many physical and electrical advantages that make it superior to the Wet Lead Acid Batteries. This also maximizes the VMAX resistance to shocks and vibrations.

Since the electrolyte is totally absorbed by the AGM, the VMAX is classified as “non-spillable and non-hazardous”.

A tough Tank seals and protects the tightly packed plates delivering the VMAX in a 100% maintenance-free package. Though VMAX Tanks are best known for their long life span, their capability to recover after repeated deep discharges is what makes them the favorite choice for any application.
