Compatible CMOS Battery for Tecra A11-14J

This lithium coin cell replaces the CMOS RTC battery on compatible Toshiba Tecra A11-14J laptop motherboards. It maintains BIOS settings and system time when the main power is disconnected. The part is supplied new and tested before shipping. One battery is included in the package.

Motherboard-Only Replacement Limitation

This component fits the motherboard CMOS socket and does not power the laptop itself. It cannot replace a failed main battery pack or charger. Buyers needing a primary power source for mobile use will find this part unsuitable for that purpose.

Lithium Chemistry Defines Fit

The lithium cell chemistry determines the voltage and physical dimensions required by the motherboard socket. Verifying that the original battery uses the same lithium type is the single check that confirms compatibility.

Lithium chemistry provides stable 3 V power to keep the real-time clock and BIOS settings alive while the laptop is off or unplugged.
