What this product is

The DBTLAP CMOS battery is a lithium coin cell built to replace the BIOS RTC backup cell on the Sony VAIO VPCF135FG/B motherboard. It ships new and tested, ready to restore system time and firmware settings when the original cell fails.

Who it suits and who should look elsewhere

This part suits owners of the specified VAIO model who need a direct replacement for a depleted CMOS battery. It does not suit anyone repairing a different laptop series, a desktop board, or the main laptop power pack, because the connector and form factor are model-specific.

Deciding specification

Battery Type: Lithium. Match this chemistry and the VPCF135FG/B compatibility before ordering, as other coin-cell types or pin layouts will not fit the motherboard socket.
