The Power-Sonic PS-12180 F2 12V 18Ah SLA AGM Battery provides dependable rechargeable power for general-purpose and standby applications. It combines sealed lead-acid construction with Absorbent Glass Mat technology for reliable, maintenance-free operation. In addition, its 18Ah capacity makes it suitable for fire and security systems, emergency lighting, UPS equipment, medical devices, and other backup power applications.
Reliable 12V 18Ah Power
The Power-Sonic PS-12180 F2 provides a nominal voltage of 12 volts and a rated capacity of 18Ah at the 20-hour rate. Therefore, it offers a practical energy storage solution for equipment that requires reliable standby power.
The battery belongs to the Power-Sonic General Purpose SLA Series. This series supports float and light cyclic applications. As a result, the battery works well in equipment that remains on standby but may need to provide power during an outage or system event.
Sealed AGM Technology
Absorbent Glass Mat technology holds the electrolyte within the battery. Therefore, users do not need to add water or perform routine electrolyte maintenance.
The valve-regulated design also provides spill-resistant operation under normal conditions. Moreover, gas recombination technology supports efficient charging and dependable long-term performance.
F2 FASTON Terminals
This model uses F2 FASTON quick-disconnect terminals. The F2 tabs measure approximately 0.250 × 0.032 inches. Therefore, buyers should confirm the terminal configuration before replacing an existing battery.
Terminal type plays an important role in proper installation. Always compare the voltage, capacity, terminal size, and physical dimensions with the original battery.
