LightAlarms PB28D replacement battery

The LightAlarms PB28D cartridge supplies a single 6V 7Ah sealed lead-acid cell built for high-rate discharge. It fits security panels and UPS units that require this exact form factor and terminal layout.

Sustained load behaviour

The high-rate design delivers steady current during extended backup events without the voltage sag common in standard cyclic cells. It is not suited for deep-cycle solar storage or applications demanding repeated full discharges.
