Compatible CMOS RTC Battery for 1215

This lithium coin-cell battery replaces the CMOS BIOS RTC backup cell on the ASUS Eee PC 1215N motherboard. It keeps the real-time clock and BIOS settings alive while the main power is off. The part is supplied new and tested before shipment. It is not a main laptop battery and will not power the system.

Lithium coin-cell voltage and lifespan limits

A standard 3 V lithium cell typically holds charge for several years but will eventually self-discharge. If the system loses time or BIOS settings after shutdown, the cell has reached its practical end of life. No recharging circuit exists for this battery type on the motherboard.

Direct replacement for a depleted original cell

Swapping the old battery restores persistent clock and configuration storage without board-level repair. The upgrade is worth it when the laptop shows CMOS checksum errors, date resets or failure to retain boot order. Builders needing a higher-capacity or rechargeable alternative cannot use this form factor.
