ASUS 1025CE CMOS replacement battery

This lithium CMOS battery is built for the ASUS 1025CE laptop motherboard. It supplies the low-voltage power that keeps BIOS settings and the real-time clock running when the main battery is removed or depleted. The part is intended for owners of that specific model who need to restore firmware memory retention. It is not a main laptop battery and will not power the system for portable use.

Single tested unit in the package

The box contains one CMOS battery that has been checked before shipping. No cables, brackets, adapters or software are included, so the buyer must reuse any existing connector or holder from the original board. The pre-ship test reduces the chance of receiving a dead cell, but installation still requires opening the laptop chassis and basic soldering or plug-in skill. Users without repair experience should seek professional help.

Lithium coin-cell limits

Lithium coin cells deliver stable voltage for years but cannot be recharged and will eventually exhaust. The battery operates within the narrow voltage window the motherboard expects, so it cannot compensate for a faulty charging circuit or a board-level power leak. Extreme temperatures shorten service life, and the cell must be disposed of according to local hazardous-waste rules. It is not suited for devices that require a rechargeable backup source.
