Description

ALL POWER-SONIC Maintenance Free Batteries feature lead calcium expanded grids (lead calcium technology) for improved resistance to corrosion, gassing, and water usage, self-discharge and thermal runaway, all of which limit battery life in conventional lead acid batteries. This high performance range of Heavy Duty Batteries are built to withstand all terrains and beatings. They are purposely built with extra thick plates for a greater crank and vibration resistance.

The Extra Heavy Duty range has been designed to last longer in demanding applications where there is a higher than normal demand for powering extra loads. They have the same features as the Heavy Duty range, as well as the addition of the new thicker grids with extra paste on the plates and glass mat envelope separators.
