Compatible CMOS Battery For Samsung Q25

This lithium CMOS battery is a direct replacement for the Samsung Q25 laptop motherboard. It supplies the low-voltage power needed to retain BIOS settings and the real-time clock when the main system is off. The unit is tested before shipping and arrives new in a single-piece package. It is not a main laptop battery and will not power the device during use.

For Owners Of A Samsung Q25 With A Dead BIOS Battery

This part suits anyone whose Samsung Q25 loses the date, time or boot configuration after shutdown. It will not help users who need a replacement for the primary rechargeable battery pack that runs the laptop. Buyers with a different laptop model should verify the exact connector and voltage before ordering.

Fits Directly On The Motherboard Of The Samsung Q25

Installation requires opening the chassis to reach the coin-cell socket on the board; no soldering or additional cables are needed. The battery frees the system from CMOS checksum errors and time drift without drawing power from the main supply. Ensure the laptop is disconnected from all power sources before swapping the cell.
