What this battery replaces

This is a lithium CMOS RTC battery built for the Acer Aspire 7736Z motherboard. It keeps the real-time clock and BIOS settings alive when the main power is off. Buyers who need a main laptop battery will not find it here.

Limits of the CMOS interface

The cell supplies a steady low voltage to the firmware chip only. It cannot power any system component, charge over USB or run the laptop on its own. A depleted unit shows itself through lost time, date or boot-order settings after every shutdown.

Installing the coin cell

The part arrives tested and ready to fit the designated socket on the 7736Z board. Polarity must match the original orientation; reversing it will prevent the clock from holding data. No soldering or special tools are required for the swap.
