DBTLAP CMOS Battery for Sony VAIO VPCF13Z1E/B

This lithium coin cell replaces the CMOS RTC battery on the motherboard of the Sony VAIO VPCF13Z1E/B laptop. It keeps the real-time clock and BIOS settings active when the main power is removed. The part is new and tested before shipping. It is not a main laptop battery and does not power the system.

CMOS battery practical limits

A CMOS battery typically lasts several years before the clock drifts or BIOS settings reset at every cold start. When the cell is depleted the laptop will still boot but the date and time must be re-entered each session. The replacement requires opening the chassis to reach the motherboard socket.

Upgrade from a dead or leaking cell

Replace the original battery when the system loses time, shows checksum errors or the old cell shows corrosion. The jump is worth it as soon as those symptoms appear because a fresh cell restores persistent firmware settings immediately. Buyers who need a main power pack or a higher-capacity coin cell will not be served by this part.
