CMOS Battery for Sony Vaio VGN-FS315B

This lithium CMOS battery is built for the Sony Vaio VGN-FS315B laptop motherboard. It maintains BIOS settings and the real-time clock when the main power is removed. The part is new and tested before it leaves the supplier. It is intended for technicians or owners replacing a depleted or damaged RTC cell.

Replaces a Dead or Faulty RTC Cell

The battery takes the place of the original CMOS cell that has lost its charge or developed a fault. A swap is worth it when the system loses date, time or BIOS configuration after shutdown. It is not a main laptop battery and will not power the device for portable use. Buyers needing a primary power source should look elsewhere.

Limited to Lithium Coin-Cell Format

The component uses a standard lithium coin-cell design that fits the motherboard holder for this model. It cannot be recharged and must be replaced again once its voltage drops below the threshold required by the RTC circuit. No other interface, chemistry or form factor is supported by this part.

Highlights

  • Direct Sony Vaio VGN-FS315B compatibility
  • Lithium cell maintains BIOS clock and settings
  • Tested before shipping for reliable operation
  • Replaces faulty or cracked CMOS battery

Questions about this item

What connector does the CMOS battery for the Sony Vaio VGN-FS315B use to attach to the motherboard?

The DBTLAP CMOS battery includes a pre-wired connector that plugs directly into the motherboard header on the Sony Vaio VGN-FS315B.

How do I install the replacement CMOS battery in the Sony Vaio VGN-FS315B without damaging the connector?

Remove the old battery, align the new connector with the motherboard header, and press straight in until it seats fully — forcing it at an angle bends the pins.

When should I expect to replace the CMOS battery in my Sony Vaio VGN-FS315B again?

A lithium CMOS battery typically maintains BIOS settings for several years; replace it when the system loses the date or shows CMOS checksum errors on boot.
