CMOS battery for Satellite 5105-S701

This DBTLAP lithium CMOS battery replaces the onboard RTC cell on the Toshiba Satellite 5105-S701 motherboard. It maintains BIOS settings and the real-time clock when the main power is removed. The part is supplied new and tested before shipping. It is intended for laptop motherboards, not the main laptop battery pack.

Single replacement cell in the box

The package contains one CMOS battery and no additional cables, adapters or software. Installing it restores the ability to retain system configuration and time between shutdowns. No drivers or firmware updates are required for the swap.

For owners of the 5105-S701 with a dead RTC cell

This suits anyone whose Satellite 5105-S701 loses BIOS settings or shows a checksum error at boot. It does not address main battery runtime, charging issues or power delivery faults. Buyers needing a primary power pack or a different form-factor cell should look elsewhere.

Highlights

Questions about this item

How often does the lithium CMOS battery in the Satellite 5105-S701 require replacement?

The lithium cell typically lasts several years; replace it when the system loses date, time or BIOS settings after power is removed.

What is the first limitation encountered when the CMOS battery runs continuously in the Satellite 5105-S701?

The limiting factor is the cell's finite capacity — once depleted, the real-time clock and CMOS memory stop retaining data.

Does the CMOS battery generate noticeable heat or noise during all-day operation in the Satellite 5105-S701?

No, the lithium CMOS battery is a passive component that produces no audible noise and negligible heat while maintaining the real-time clock.
