Batteries built to last through tough, everyday use.

Power-Sonic SLA batteries serve as fuel for commercial transit vehicles, security electronics, and in many boats and RVs.

Superior Facilities, Superior Hands

At the zenith of SLA technology, Power-Sonic separates itself from the competition.

Power-Sonic batteries use special Gel-Power technology to change the way energy flows through the battery. Thick, thixotropic gel preserves electrolytes in anticipation of use. Gel-Power works better than older SLA batteries, where acid would sit freely in the battery pack. The gel prevents corrosion, and increases the reusability of the battery.
