HP 625 CMOS Replacement

This lithium CMOS battery is designed as a direct replacement for the HP 625 laptop motherboard. It supplies the low-voltage power required to retain BIOS settings and the real-time clock when the main battery is removed or depleted. Each unit is tested before shipping to verify reliable operation. It is not a main laptop battery and will not power the system during use.

Laptop owners needing BIOS retention

The part suits owners of the HP 625 who are experiencing CMOS checksum errors, date and time resets, or lost BIOS configurations. It is not intended for users seeking a primary power source to run the laptop unplugged, nor for models outside the specified compatibility. Builders working on other chassis or motherboard designs should verify the exact connector and voltage requirements before purchasing.

Lithium cell capacity and limits

The coin-cell format delivers the standard capacity expected for CMOS backup duties, comfortably maintaining firmware settings for extended periods while the system is off. It will not sustain high-current loads, drive peripherals, or replace a failed main battery pack. When the cell eventually exhausts its charge, BIOS data will again be lost until a fresh replacement is fitted.
