Compatible CMOS Battery for Samsung 900X3C-A01AU

This lithium CMOS battery replaces the BIOS RTC cell on Samsung 900X3C-A01AU laptop motherboards. It is not a main laptop battery and will not power the system. The unit is new and tested before shipping. Buyers who need a main power pack or a different form factor cannot use this part.

Replaces a Dead or Leaking Motherboard Coin Cell

Swap this in when the original CMOS battery fails and the system loses time, date or BIOS settings. The jump is worth it if the laptop shows checksum errors or refuses to boot because the RTC voltage has dropped. Builders who need a rechargeable main pack or a higher-capacity cell should look elsewhere.

Lithium Coin-Cell Limits on Modern Motherboards

The lithium chemistry provides stable voltage for real-time clock circuits but cannot supply load current for any other component. It fits only the designated CMOS holder on the target board. Users who expect hot-swap capability or extended runtime for peripherals will find the interface unsuitable.
