Power-Sonic PHR-12300 High Rate VRLA Battery

Tested for greatness, the PHR-12300 is a VRLA battery that surpasses the competition with little effort.

Like most Power-Sonic batteries, the PHR-12300 from the High Rate VRLA series uses quality parts and chemistry to deliver superior performance. Power-Sonic's PHR-12300 Sealed Lead Acid continues the tradition of quality and excellence, administering 12 volts of power constantly, and rated for a capacity of 80AH. With no maintenance outside of regular cleaning and charging, this SLA battery is the energy answer for floor machines, UPS systems and off-road vehicles everywhere.

Peak Performance

Thanks to Power-Sonic builders, customers enjoy efficient and effective energy for years.

Every Power-Sonic SLA battery is constructed with the job in mind. Whether installed in UPS systems or as a backup battery for motorcycles, sealed lead acid batteries work.Consistent, high-rate discharge increases the overall life of the battery, allowing users up to a decade of rechargeable power for smaller vehicles and power supplies.

Consistent Power

Improved plate mechanics yield better than ever consistency rates for Power-Sonic SLA batteries.

Power-Sonic uses a technique known as precision plate pasting when building their batteries. Inside every SLA battery are a series of plates woven with strong fiberglass to increase surface area, and improve the effectiveness of the battery. Rather than flooding the plates with acid to gain electrolytes, AGM technology keeps the battery mostly dry, getting just wet enough to hold a strong charge for use in powering various machines and UPS systems.Every battery is load tested to make sure uniform capacity is reached across the plates.
