Compatible CMOS Battery

This lithium CMOS battery is built for the ASUS Eee PC 1215N motherboard. It supplies the low current needed to keep BIOS settings and the real-time clock alive when the main power is off. The part arrives new and tested, ready to replace a depleted or leaking original cell. It is not a main laptop battery and will not power the system itself.

Direct Replacement Fit

The battery matches the original form factor so it seats in the existing holder without adapters or soldering. A simple swap restores CMOS function and eliminates checksum errors or time resets on boot. No extra cables or mounting hardware are included because the board socket provides the connection. Build quality is consistent with standard lithium coin-cell production.

Lithium Cell Chemistry

The single specification that decides fit is the lithium chemistry used for the RTC circuit. Only a lithium coin cell delivers the correct voltage and shelf life for this motherboard. Buyers who need a rechargeable main power pack or a different voltage should look elsewhere. The package contains one tested cell.
