CMOS Battery for ASUS c90s

This DBTLAP lithium CMOS battery replaces the BIOS RTC cell on ASUS c90s laptop motherboards. It is a direct-fit component for restoring system time and firmware settings. The pack contains one tested unit ready for installation.

Interface and voltage limits

The battery uses a standard lithium coin-cell chemistry with a nominal three-volt output. Polarity and physical dimensions must match the motherboard holder exactly. No soldering or adapter is required when the original specification is identical.

Replaces a dead or leaking original cell

Swap this in when the laptop loses date and time after shutdown or shows CMOS checksum errors. The upgrade is worth it if the existing battery reads below three volts or shows corrosion. It is not for buyers who need a main laptop power battery or a higher-capacity CMOS variant.
