Compatible CMOS Battery for ASUS M70

This lithium CMOS battery is designed as a direct replacement for the real-time clock backup cell on ASUS M70 laptop motherboards. It supplies the low-voltage power required to retain BIOS settings and system time when the main battery is removed or depleted. The part is intended for technicians or owners servicing this specific model. It is not a main laptop power battery and will not operate the system on its own.

Simple Two-Wire Installation

The battery arrives pre-tested with a two-wire connector that plugs into the motherboard header, so no soldering is required. Installation typically involves opening the chassis, locating the CMOS socket near the board edge, and swapping the old cell for the new one. The main risk is reversing the connector polarity or dislodging nearby ribbon cables during the swap. Buyers who have never opened a laptop chassis may prefer professional fitting.

Lithium Chemistry for RTC Retention

The single specification that determines fit is the lithium coin-cell chemistry matched to the ASUS M70 motherboard voltage and connector pin-out. A different chemistry or voltage will not hold the real-time clock reliably. Buyers needing a main system power pack or a battery for a different laptop series should look elsewhere.
