DBTLAP CMOS Battery for Compaq Mini CQ10-110ES

This replacement CMOS battery is designed specifically for the Compaq Mini CQ10-110ES laptop motherboard. It restores BIOS and real-time clock function when the original cell fails. The part is supplied new and tested before shipping. It is not a main laptop power battery.

Lithium coin cell interface limits

The lithium coin cell provides the low continuous current required for CMOS memory retention. It cannot power the laptop or charge other components. Voltage and physical dimensions follow the standard for this motherboard socket. Polarity must match the original installation exactly.
