Compatible CMOS Battery

The DBTLAP lithium CMOS battery replaces the BIOS RTC cell on Sony Vaio VGN-TXN15P/W laptop motherboards. It is a new component tested before shipping to ensure reliable real-time clock operation. This part addresses the motherboard coin cell only and is not a main laptop battery.

Single Unit Package

The bundle includes one replacement CMOS battery and no additional cables, brackets or software. Installing the single cell restores system time and BIOS settings retention without extra accessories. Buyers who need a multi-pack or a full laptop battery kit will not find those items here.

Lithium Coin Cell Limits

The lithium chemistry provides standard voltage for CMOS memory but has a finite service life determined by motherboard current draw. It cannot be recharged and must be replaced again when the clock drifts or settings clear. Systems requiring a different voltage or form factor cannot use this cell.

Questions about this item

How often will the lithium CMOS battery need replacement in the Sony Vaio VGN-TXN15P/W?

The lithium CMOS battery typically lasts several years before the system clock drifts or BIOS settings reset, signalling it is time for a new one.

What is the first limit reached when the CMOS battery runs continuously in the Sony Vaio VGN-TXN15P/W?

The first limit is voltage drop; once the cell can no longer hold a charge the real-time clock stops keeping accurate time.

Does the CMOS battery generate noticeable heat or noise during all-day operation in the Sony Vaio VGN-TXN15P/W?

No, the coin-cell CMOS battery draws microamps and produces no audible noise or perceptible heat while the laptop runs.
