Replacement CMOS Battery for Tecra M11-S3430

This DBTLAP lithium cell is a direct replacement for the CMOS RTC battery used in the Toshiba Tecra M11-S3430 laptop. It restores the real-time clock and BIOS settings retention when the original coin cell fails. The part is supplied new and tested before shipping. It is intended for motherboard-level maintenance, not for main laptop power.

Lithium coin-cell chemistry

The battery uses a standard lithium chemistry suited for low-drain CMOS memory backup on the motherboard. It provides the 3 V nominal voltage required by the RTC circuit. No other specifications such as capacity, dimensions or connector type are provided in the source data. Compatibility is limited to the specific model listed.

Maintains BIOS settings and system clock

A fresh cell comfortably keeps the system clock running and preserves BIOS configuration for years under normal standby conditions. It cannot power the laptop itself or support any high-drain function. Buyers who need a main laptop battery or a higher-capacity backup solution should look elsewhere.
