Direct Replacement CMOS Battery

This DBTLAP lithium CMOS battery is built for the Sony VAIO VGN-TZ150N/N motherboard. It stores BIOS settings and keeps the real-time clock running when the main power is off. The unit arrives new and is tested before shipping. One battery is included in the package.

For Owners Needing a BIOS Battery Fix

Suits anyone whose VAIO VGN-TZ150N/N loses the date, time or boot configuration after shutdown. It is not a main laptop battery and will not power the system for portable use. Buyers who need a primary power pack for mobile operation should look at a different product.

Lithium Coin-Cell Chemistry

The cell uses lithium chemistry to provide the stable low current required by the CMOS circuit. This single specification determines whether the part matches the motherboard design.

Questions about this item

What connector does the DBTLAP CMOS battery use to fit the Sony VAIO VGN-TZ150N/N motherboard?

The battery is built to match the original CMOS connector on the VGN-TZ150N/N motherboard, so it plugs straight in without adapters.

What is the installation step people often miss when replacing the CMOS battery on this VAIO?

After fitting the new cell you must enter the BIOS and reset the date, time and boot order, otherwise the laptop will keep losing settings.

How long before the DBTLAP CMOS battery in a VGN-TZ150N/N typically needs replacing again?

A fresh lithium CMOS cell usually lasts several years; when the system clock starts drifting or BIOS settings disappear, it is time for a new one.
