Direct replacement for ASUS U50A

This CMOS RTC battery is a direct replacement for the ASUS U50A laptop motherboard. It restores BIOS settings and real-time clock function when the original cell fails. The lithium coin cell is new and tested before shipping. Install it to fix date resets and CMOS checksum errors.

Steady voltage over years

The lithium chemistry delivers a stable low current for continuous RTC operation rather than short bursts. It maintains the system clock and CMOS memory without interruption during long periods of mains power loss. Each unit is verified to hold voltage before it leaves the supplier. Expect consistent performance throughout its service life.

Snap-in coin cell format

The standard coin cell shape fits the motherboard holder without soldering or adapters. One battery is included in the package for a single swap. The compact size leaves surrounding components accessible during installation. No cables or extra hardware are required for day-to-day use.
