Direct replacement for Tecra A11-S3540

This DBTLAP CMOS battery is a direct replacement for the Toshiba Tecra A11-S3540 motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The lithium coin cell is supplied new and tested before shipping. It is intended for laptop motherboards, not the main laptop battery.

Simple two-wire installation

The battery arrives with a pre-attached connector for a straightforward swap on the motherboard. No soldering is required if the existing header matches. The main risk is polarity reversal; the keyed plug prevents this when inserted correctly. Careless handling can bend the fragile header pins on the board.

Keeps BIOS settings for years

A fresh lithium cell typically maintains CMOS data for several years of continuous use. It comfortably handles date, time and boot-order retention during long power-off periods. The battery runs out when the system clock drifts or BIOS defaults reappear at every cold start. Replacement restores reliable operation.
