DBTLAP CMOS Battery for Satellite Pro P300-1A6

This lithium CMOS battery is a direct replacement for the BIOS real-time clock cell on Toshiba Satellite Pro P300-1A6 laptops. It restores system time, date and BIOS settings that are lost when the original cell fails. The part is new and tested before shipping. It is intended for motherboard maintenance, not for main laptop power.

Drop-in motherboard replacement requiring basic

The battery fits the existing holder on the laptop motherboard and requires only a small Phillips screwdriver and careful case opening to install. No soldering or additional cables are needed. Replacing the cell frees the system from CMOS checksum errors and eliminates the need to reset the clock at every boot.

Upgrades a depleted or leaking factory CMOS cell

The swap is worth it when the laptop loses time, shows CMOS checksum errors or fails to retain BIOS changes after shutdown. It does not address main battery life, charging issues or power-on failures unrelated to the RTC circuit. Buyers needing a main laptop battery or a different form-factor CMOS cell should look elsewhere.

Questions about this item

How long does the lithium CMOS battery last under continuous use?

The lithium cell maintains BIOS settings and the real-time clock for years of continuous operation before voltage drops below the threshold that triggers a CMOS checksum error.

Does the battery generate noticeable heat or noise during all-day operation?

No, the coin-cell design produces no audible noise and negligible heat while supplying the microamp currents needed for the RTC and CMOS memory.

What connector or cable must the motherboard already have for this battery to work?

The motherboard needs a standard two-pin CMOS header with the correct polarity and pin spacing to accept the battery’s pre-attached lead.
