  • Lithium cell maintains BIOS settings and system clock
  • Tested before shipping to ensure reliable operation
  • Single battery included for straightforward installation
  • Designed for CMOS RTC function, not main laptop power

CMOS battery for Toshiba Satellite M305D

This lithium CMOS battery replaces the BIOS RTC cell on a Toshiba Satellite M305D motherboard. It is a new component tested before shipping. The package includes one battery intended for motherboard firmware power, not the main laptop battery.

Long-term voltage stability for firmware retention

The cell provides steady low-current power so system time, boot order and hardware settings survive when the main battery is removed or depleted. It maintains the real-time clock and CMOS memory without the voltage drops that cause configuration loss during extended storage.

Direct motherboard fit without adapter cables

The battery connects to the existing CMOS header on the Satellite M305D board, so no soldering or converter is required. Builders working on other Toshiba models or different laptop brands will need a battery matched to those specific motherboard pinouts and form factors.

Questions about this item

Does the lithium CMOS cell generate any noticeable heat or noise while the Toshiba Satellite M305D runs continuously?

The CMOS battery only powers the real-time clock with a tiny current, so it produces no audible noise and no detectable heat during all-day operation.

What connector or cable must already be on the motherboard for this DBTLAP CMOS battery to work?

The board needs a standard two-pin CMOS header that matches the battery's lead spacing.

Will this replacement CMOS battery keep the correct date and time on an older Toshiba Satellite M305D that has been in storage?

Yes, the lithium cell restores the RTC function so the system clock maintains accurate time after long periods without main power.
