DBTLAP CMOS Battery for Toshiba Tecra A11-17M

SKU CH-DRBY-3Y6FM

A lithium CMOS battery that keeps the system clock and BIOS settings on Toshiba Tecra A11-17M laptops

  • Battery TypeLithium
  • Keeps BIOS settings accurate with lithium CMOS battery
  • Ready to install as direct replacement for Tecra A11-17M
  • Tested before shipping to ensure reliable operation
  • Includes single battery for straightforward motherboard repair
  • New lithium cell restores real-time clock function

Direct Replacement for Tecra A11-17M

This lithium CMOS battery is designed specifically for the Toshiba Tecra A11-17M laptop motherboard. It replaces a depleted or faulty RTC cell that causes BIOS settings and system time to reset. The unit arrives new and tested, ready for immediate installation. It restores reliable low-power memory retention for the firmware.

Simple Motherboard Installation

The battery fits directly onto the motherboard without additional cables or adapters. No soldering is required if the original connector matches the replacement. Replacing the cell frees the system from constant date and time errors on every boot. It eliminates the need to reconfigure BIOS settings after each power loss.

Lithium Cell Restores BIOS Retention

The lithium chemistry provides stable voltage for the real-time clock and CMOS memory. It comfortably handles the low current draw required to keep firmware settings alive for years. The battery runs out when the cell voltage drops below the threshold needed to maintain the RTC. A fresh unit returns the laptop to normal start-up behaviour.

Questions about this item

Does the lithium chemistry hold the BIOS clock reliably when the Tecra A11-17M runs on mains power for weeks?

The lithium CMOS cell supplies continuous backup voltage to the RTC circuit, so date and time settings persist even during extended AC-only operation.

Will the battery generate noticeable heat or draw extra power while the laptop operates all day?

CMOS batteries consume microamp-level current and produce no measurable heat or fan noise during normal system use.

What existing laptop hardware is required before fitting this replacement cell?

A Toshiba Tecra A11-17M motherboard with a standard two-pin CMOS header is needed to accept the connector.
