DBTLAP CMOS Battery for Sony Vaio VGN-UX

This lithium CMOS battery replaces the BIOS RTC cell on Sony Vaio VGN-UX laptop motherboards. It is intended for owners of that specific model who need to restore system time and BIOS settings after the original cell fails. The unit ships new and tested for immediate installation.

Steady voltage retention over years of standby

Lithium chemistry delivers a stable three-volt output that maintains CMOS memory continuously while the laptop is powered off. Unlike short bursts, this steady discharge keeps the real-time clock accurate and preserves BIOS configuration across months or years without mains power.

Limited to motherboards using this exact connector

The battery fits only boards designed for the Sony Vaio VGN-UX form factor and pin layout. Builders working on other Sony series or different brands cannot use this part, and no adapter is included for alternative sockets.
