Direct Replacement Battery

The Estry lithium cell is built to the exact specifications of the original Xfinity Home Security Screen battery. It delivers 4500mAh at 3.7V with a 16.65Wh rating. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards, it includes overcharge, over-discharge, over-voltage and short-circuit protection. This single-pack unit suits owners needing a like-for-like power source for their security panel.

Simple Swap Installation

The pack measures 74.7 x 55.0 x 9.3mm and weighs 106.4g, matching the factory footprint for a tool-free swap in most cases. Align the connector polarity exactly as the original; reversed insertion can trigger the protection circuit and prevent charging. No soldering or firmware steps are required, but verify the part number GSP055771 on the old cell before fitting the new one.

Verify Compatibility First

Confirm your panel is the Xfinity Home Security Screen model and that the existing battery carries part number GSP055771. The replacement is a 3.7V lithium chemistry only; it will not suit nickel-based or higher-voltage packs. Buyers with a different security keypad or a screen requiring a different form factor should not order this unit.
