DBTLAP CMOS Battery for Sony VAIO VPCS13V9E/B

Targeted replacement CMOS battery

This DBTLAP lithium CMOS battery is built specifically for the Sony VAIO VPCS13V9E/B laptop motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The unit ships new and pre-tested so it can be installed straight away. It is not a main laptop battery and will not power the system itself.

Direct-fit capacity for BIOS memory

The lithium cell holds enough charge to keep CMOS data alive during long periods without mains power. It comfortably handles the low continuous draw of the real-time clock and configuration registers. Capacity runs out only when the cell reaches end of life after several years of service. No larger or higher-capacity alternative fits the same socket.

Standard coin-cell interface limits

The battery uses the common coin-cell form factor that mates directly with the motherboard holder. Polarity and physical dimensions are fixed by that socket so no adapter or cable modification is possible. Voltage and chemistry are defined by the lithium standard the board expects. Builders needing a rechargeable or different chemistry cell cannot use this part.
