Compatible Sony VAIO VGN-CR220E/P CMOS Battery

This lithium CMOS RTC battery is designed for the Sony VAIO VGN-CR220E/P laptop motherboard. It replaces a faulty or depleted BIOS backup cell to keep system time and firmware settings intact. Buyers needing a main laptop power battery should look elsewhere.

Tested Lithium Cell with Direct Fit

Each unit is tested before shipping to ensure reliable voltage delivery. The form factor matches the original motherboard connector, allowing a straightforward swap without soldering or adapter cables. Builders without access to the motherboard header will not be able to install it.

Single Battery in Protective Packaging

The package includes one CMOS battery sealed for transit protection. No tools, cables or software discs are supplied, so the buyer must provide any small screwdrivers or opening tools required for their specific chassis. Users expecting a multi-pack or installation kit will need to source those separately.
