DBTLAP CMOS Battery for Toshiba Satellite A100

This replacement CMOS battery restores BIOS settings and real-time clock function on Toshiba Satellite A100 laptops. It is a direct fit for the motherboard coin-cell socket and ships tested and ready to install. The lithium cell provides stable voltage for firmware retention when the main power is removed. Suitable for technicians or owners repairing a unit that loses date, time or boot configuration.

Sustained reliability

The lithium chemistry delivers consistent voltage over the long intervals between main-battery charges or AC sessions. It maintains CMOS memory without drift during weeks of storage or daily sleep cycles. Each cell is verified before dispatch to confirm it holds spec under the low continuous drain of the RTC circuit. No capacity fade is expected during normal service life in this application.

Upgrade from a depleted original

Replaces a dead or leaking factory-fitted coin cell that causes checksum errors, lost passwords or failure to POST. The swap is worthwhile when the laptop shows wrong system time, refuses to save BIOS changes or prompts for setup on every boot. Not for buyers who need a main laptop battery or a higher-capacity CMOS cell than the original specification.
