Power-Sonic PHR-12100 High Rate VRLA Battery

With no maintenance required, Power-Sonic's High Rate Series batteries outperform the competition

Power-Sonic ups the ante with their VRLA High Rate Series Battery. Utilizing AGM technology, these VRLA batteries discharge at a higher rate for an overall improved performance. Power-Sonic designers house this powerful sealed lead acid battery in ABS plastic, a highly durable, flame retardant material. These batteries are rechargeable over several hundred cycles, fueling UPS, ATV, and other portable power needs across the map for up to a decade.

Improved Design

Power-Sonic high rate batteries use special inner construction and other processes to improve overall performance.

AllVRLA High Rate Batteries use high-quality parts and chemistry to produce such a superior battery. Precision plate pasting creates a higher consistency of electrolytes for use. Patented plate pasting improves active material bonding in the overall power process.

AGM Technology

Power-Sonic designs batteries that transport safely and work effectively.

The Power-Sonic PHR-12100 is a sealed lead acid battery on a mission. Special AGM technology weaves glass fibers into strong receptors that house electrolytes waiting to be used. This allows Power-Sonic High Rate SLA batteries the power to burst off large amounts of energy from storage. Along with better energy distribution and storage, AGM technology is a safer way to store SLA power. There is no free liquid inside these batteries, minimizing risk and chance of accident.
