DBTLAP CMOS Battery for Sony Vaio

This lithium CMOS battery replaces the BIOS RTC cell on Sony Vaio VGN-TXN17P/B laptop motherboards. It is a dedicated motherboard battery, not a main laptop power pack. The unit arrives tested and ready for installation. One battery is included in the package.

Replaces a dead or leaking CMOS cell

Swap this in when the system loses date, time or BIOS settings after power-off. The jump is worth it if the original CR-type cell has failed or shows corrosion on the holder. It restores persistent firmware configuration without changing any other hardware.

Holds voltage steadily under continuous trickle load

The lithium chemistry delivers stable 3 V output for the real-time clock circuit over years of standby operation. It maintains charge through daily power cycles and long storage periods. No sudden voltage sag occurs during sustained low-current draw.
