DBTLAP CMOS Battery for Acer Extensa 2303LMi

This DBTLAP lithium CMOS battery is a direct replacement for the real-time clock cell on the Acer Extensa 2303LMi motherboard. It supplies the low-voltage power needed to retain BIOS settings and system time while the laptop is turned off or unplugged.

Replaces a depleted or leaking original cell

When the original CMOS battery fails the laptop will lose its date, time and firmware configuration on every shutdown. Swapping in this tested unit restores persistent BIOS storage and eliminates the recurring checksum errors that appear at boot.

Maintains voltage under continuous standby load

The lithium chemistry delivers a stable output during the months or years the notebook spends in sleep or hibernation. Because the cell is verified before shipping it provides reliable long-term retention without the rapid self-discharge seen in aged or counterfeit alternatives.
