Replacement Battery for Uniden Guardian Models

The Cameron Sino 2000mAh 3.7V lithium-ion cell replaces the original Uniden 634169 pack in Guardian G955, UDR744, UDR777 and UDR780 alarm panels. It delivers 7.40Wh of capacity and fits the exact 61.44 x 50.10 x 5.10mm footprint. Homeowners and installers use it to restore backup power when the factory cell no longer holds charge.

Voltage and Capacity Limits

The pack operates at a fixed 3.7 volts and 2000mAh, so it cannot support panels that require a different voltage or higher amp-hour rating. Runtime is determined by the panel's own current draw; the battery will not extend operation beyond its rated 7.40Wh. It includes over-charge, over-discharge, over-voltage and short-circuit protection, but it cannot compensate for a faulty charging circuit in the alarm unit.

Installation Notes

The fully decoded chip matches the original connector, so the battery plugs in without soldering; many users complete the swap in minutes after watching online guides. The main risk is reversing the connector or seating it loosely, which prevents the panel from recognising the new cell. A new pack reaches full capacity after two or three complete charge cycles, and the supplier cautions against using low-quality third-party chargers.
