Power-Sonic PS-1221S SLA Battery

Power-Sonic SLA batteries deliver safe, consistent energy every time for vehicles and appliances alike.

Power-Sonic's 12-volt SLA battery line sits at the heart of many electronics and vehicles. From golf-carts to UPS systems, Power-Sonic sealed lead acid batteries store energy via special AGM technology, for an overall superior performance to competing batteries. Built to last, Power-Sonic invests in strong ABS plastic for an almost spill-proof case with strong impact resistance. Rated for 2 AH, this 12-volt sealed lead acid battery will change the way you store and use power across hundreds of power cycles.

AGM Technology

For high-rate and high-performance, AGM Technology stores and moves electricity better than other power storage methods.

Absorbed Glass Mat(AGM) technology improves where older sealed lead acid batteries left off. Rather than let liquids run freely, a thin fiber glass mat is soaked in battery acid and fitted between metal plates tightly, removing any chance of leak or spillage. This stores electrolytes more efficiently, and improves the overall performance of every power cycle compared to flooded-style batteries.
