Compatible CMOS battery for ASUS U43JC

This lithium CMOS battery replaces the RTC backup cell on ASUS U43JC laptop motherboards. It keeps the system clock and BIOS settings alive when the main power is removed. The part is new and tested before shipping. One battery is included in the package.

Lithium coin-cell interface limits

The battery uses a standard lithium coin-cell form factor that fits the motherboard holder designed for the U43JC. It supplies the low current needed for real-time-clock and CMOS memory retention only. It cannot power the laptop or charge other components. Polarity and physical dimensions must match the original socket exactly.

Battery type decides fit

The lithium chemistry determines the voltage and capacity profile the motherboard expects. Using a different chemistry would break BIOS retention and clock accuracy. This cell matches the original specification for the U43JC platform. Buyers needing a main laptop battery or a different form factor cannot use this part.
