Power-Sonic PS-1228 SLA Battery

AGM Technology stores and delivers power more consistently than any other battery power construction.

Inside every Power-Sonic battery is dependable quality you can trust. AGM technology removes loose battery acid, absorbed instead by a thin fiberglass plate and sandwiched tightly between battery plates for safe storage of electrolytes. F1 terminals are easily adaptable connector blades for a variety of vehicles and electronics including forklifts, home alarm systems, and electric wheelchairs. Durable ABS Plastic protects the battery, fortified for rugged, daily use.
