Compatible CMOS RTC Battery

This DBTLAP lithium cell replaces the CMOS RTC battery on a Toshiba Satellite L655-S5157 laptop motherboard. It is a dedicated motherboard coin cell, not a main laptop battery. The unit is new and tested before shipping.

Lithium coin cell chemistry

The battery uses lithium chemistry to maintain BIOS settings and the real-time clock when the laptop is powered off. A fresh cell restores reliable boot configuration and accurate timekeeping after the original fails.

For owners of the Satellite L655-S5157

This part suits anyone whose L655-S5157 shows date reset, checksum errors or BIOS loss. It does not suit users needing a main power battery or those servicing a different laptop model.
