Compatible CMOS Battery for Sony VAIO VPCY11M1E

This DBTLAP lithium CMOS battery is designed for the Sony VAIO VPCY11M1E laptop motherboard. It replaces a depleted or faulty BIOS RTC cell that keeps system time and firmware settings. The part is new and tested before shipping. It is not a main laptop power battery.

Verify Motherboard Connector and Clearance

Check the existing CMOS cell on the motherboard to confirm the connector type and lead length match this replacement. Ensure there is enough space around the socket for the new unit. This battery is intended for motherboard use only and will not power the laptop itself. Buyers who need a main laptop battery should look elsewhere.

Steady Low-Current Operation Over Years

The lithium chemistry delivers a stable low current to the real-time clock and CMOS memory for extended periods. It maintains voltage during continuous idle operation rather than short bursts. The cell is tested before dispatch to confirm reliable performance. No high-drain capability is provided or implied.
