DBTLAP CMOS Battery for Toshiba Satellite P305D

This lithium CMOS battery replaces the BIOS RTC cell on Toshiba Satellite P305D laptop motherboards. It maintains system time and firmware settings when the main power is disconnected. The part is new and tested before shipping. It is not a main laptop battery and will not power the system during use.

Sustained reliability for firmware retention

The lithium chemistry delivers a stable voltage over the long periods a CMOS cell must operate without recharge. It keeps the real-time clock running and preserves BIOS configuration through weeks or months of mains disconnection. The battery is intended for continuous low-drain service rather than burst current delivery. Performance depends on motherboard current draw and ambient temperature.

Direct replacement for a dead or failing CMOS cell

This unit replaces an original CMOS battery that no longer holds voltage, which causes clock drift, lost BIOS settings or boot errors. The upgrade is worth it when the laptop shows those symptoms or when the original cell has reached its typical service life. Buyers who need a main power battery or a different form factor should look elsewhere.

Questions about this item

How much power does the CMOS battery draw while the laptop runs all day?

The lithium CMOS battery supplies a tiny standby current to the real-time clock and draws virtually no power during normal operation.

What must I already have inside the Satellite P305D for this battery to work?

You need the original motherboard header and wiring harness that accept the CMOS battery connector.

Will this CMOS battery work with the original motherboard firmware in the Satellite P305D?

Yes, it is a direct replacement for the factory CMOS battery and keeps the BIOS settings and system clock running on the existing firmware.
