Power-sonic PS-12120F2 Lead Acid Battery 12V 12ah

Product Description

The POWER-SONIC PS-12120F2 is a rechargeable sealed lead acid battery rated at 12 volts and 12 ampere-hours (Ah), designed for use in standby power, security, and backup power applications. It features a quick-disconnect tab terminal style for fast, tool-free connections in high-cycle service environments. Measuring 5.95 inches in depth, 3.86 inches in width, and 3.70 inches in height, the PS-12120F2 is compact enough for panel-mount enclosures and equipment bays. At 8.5 pounds, it delivers a practical capacity-to-weight ratio for replacement and OEM applications. UL listed to support installations requiring certified components.

The PS-12120F2 is suited for residential and light commercial backup power systems, including alarm panels, access control units, emergency lighting, and uninterruptible power supply (UPS) equipment. The quick-disconnect tab terminals — 0.25 inches wide and 0.031 inches thick — allow direct connection to standard push-on harness connectors without soldering or additional hardware. Electricians, security system installers, and fire-alarm technicians commonly specify this battery type for periodic replacement in life-safety equipment cabinets.

Installation Notes

Battery replacement in life-safety and alarm systems should be performed by a qualified electrician or licensed low-voltage technician following local electrical codes and NEC guidelines. Disconnect the system charger and de-energize the panel before removing the existing battery. Verify terminal polarity before connecting the new battery to avoid reverse-polarity damage to connected equipment. Dispose of the removed lead acid battery in accordance with local hazardous materials regulations.
