Compatible CMOS Battery for Tecra A8-EZ8312

This DBTLAP lithium CMOS battery replaces the original RTC cell in the Toshiba Tecra A8-EZ8312. It supplies the low-voltage power that keeps the system clock and BIOS settings alive while the main battery is removed or depleted. The part arrives new and tested, ready for direct installation on the motherboard.

Replaces a Dead or Failing RTC Cell

Swap this battery when the laptop loses its date and time after shutdown, reports CMOS checksum errors, or refuses to retain BIOS changes. The upgrade is worth it whenever the original coin cell no longer holds a charge, restoring reliable boot behaviour without replacing the main power pack.

Maintains BIOS Settings and System Clock

One lithium cell provides enough capacity for years of real-time-clock operation under normal use. It comfortably handles daily power cycles and extended periods unplugged. Headroom ends when the cell voltage drops below the threshold required by the motherboard RTC circuit, at which point settings are lost again.
