Compatible CMOS battery for Toshiba NB100-111

This lithium CMOS battery replaces the original RTC cell on Toshiba NB100-111 laptop motherboards. It restores BIOS settings retention and system clock accuracy when the factory battery fails. The unit is new, tested before shipping and intended for motherboard installation only.

Practical limits of a coin-cell RTC interface

A CMOS battery supplies microamp-level current to the real-time clock and CMOS memory when mains power is absent. It cannot power the laptop itself and will not charge from the main battery or AC adapter. Service life depends on motherboard leakage current and ambient temperature.

Direct-fit replacement for NB100-111 motherboards

The battery is built to match the voltage, form factor and connector required by the NB100-111 platform. Buyers whose laptops use a different motherboard layout or connector type will need a different part..verify compatibility before purchase.

Questions about this item

Which CMOS battery version fits the Toshiba NB100-111?

This DBTLAP lithium cell is built to match the NB100-111 motherboard socket, so the single version supplied is the correct one.

What does the lithium chemistry mean once the battery is installed?

It holds the real-time clock and BIOS settings reliably for years without needing a recharge circuit.

What interface does the battery use and what does that limit?

A two-pin connector plugs directly onto the motherboard, limiting use to boards with that exact header layout.
