Compatible CMOS battery for ASUS N5

This lithium CMOS battery replaces the BIOS RTC cell on ASUS N5 laptop motherboards. It is not a main laptop battery and will not power the system when the charger is disconnected. The part is intended for owners of that specific model who need to restore date, time and BIOS settings after the original cell fails. It does not fit other laptop models or desktop boards.

Lithium chemistry and form factor limits

The cell uses lithium chemistry and supplies the low current required for real-time clock and CMOS memory retention. It cannot be recharged from the laptop's power system and will not serve as a backup power source for the CPU or RAM. Voltage and physical dimensions follow the original specification for the ASUS N5 motherboard socket, so it cannot be used in devices that require a different coin-cell size or voltage.

Simple motherboard installation

The package includes one tested battery ready for direct placement on the motherboard. Installation requires opening the laptop chassis, locating the CMOS socket and pressing the new cell into place with correct polarity. Common issues arise when the connector orientation is reversed or when the socket is damaged during removal of the old cell. No soldering or additional tools are needed beyond those required to access the board.

Questions about this item

Which CMOS battery version fits the ASUS N5?

This DBTLAP lithium cell is built specifically for the ASUS N5 motherboard, so the single listed version is the correct one.

What does the lithium chemistry mean once the battery is installed?

Lithium chemistry provides a stable 3 V supply that keeps the real-time clock and BIOS settings alive for years without recharging.

What interface does the battery use and what does it limit?

It connects via the standard two-pin motherboard header, which limits use to boards that have that exact connector layout.
