DBTLAP CMOS Battery for Sony Vaio VPCS12J1E/W

This DBTLAP lithium CMOS battery is a direct replacement for the BIOS RTC cell on Sony Vaio VPCS12J1E/W laptop motherboards. It restores system time and BIOS settings when the original coin cell fails. The unit ships new and tested, ready for installation on the mainboard. It is not a main laptop power battery and will not charge the system.

Compatibility check before ordering

Confirm that your laptop model is exactly Sony Vaio VPCS12J1E/W before purchase. This part fits the motherboard CMOS socket on that specific model only. It will not work as a main battery pack or charger for any device. Verify the existing CMOS battery form factor matches a standard lithium coin cell if you are unsure.

Replaces a dead or failing CMOS cell

Use this battery to replace a faulty, cracked or depleted CMOS battery that causes date and time reset or BIOS configuration loss. The upgrade is worth it when the laptop shows CMOS checksum errors or fails to retain settings after power off. It does not add features or capacity beyond the original specification.
