DBTLAP CMOS Battery for Sony VAIO VPCZ23K9E

This DBTLAP CMOS battery is a direct replacement for the BIOS RTC cell inside the Sony VAIO VPCZ23K9E laptop. It is a new lithium coin cell tested before shipping to ensure reliable timekeeping and hardware settings retention. The package includes a single battery intended for motherboard installation, not the main laptop power pack. Owners of this specific VAIO model can use it to resolve CMOS checksum errors or lost system time.

Suitable for VAIO VPCZ23K9E owners needing a CMOS

This part suits technicians or owners repairing the exact Sony VAIO VPCZ23K9E model where the CMOS battery has failed. It is not for users replacing the main rechargeable laptop battery that powers the system when unplugged. Buyers with different Sony VAIO series or other laptop brands should verify their motherboard battery type before purchasing. This item addresses only the small coin-cell slot on the system board.

Lithium coin cell chemistry determines compatibility

The single deciding specification is the lithium coin-cell chemistry used for the real-time clock circuit. Your motherboard must accept this standard lithium CMOS form factor for the replacement to function correctly. No other electrical ratings or physical dimensions are provided in the data, so confirm the original cell matches this chemistry. If the board requires a different cell type or voltage, this battery will not work.
