DBTLAP CMOS Battery for Fujitsu LifeBook AH530

This DBTLAP CMOS battery is a direct replacement for the Fujitsu LifeBook AH530 laptop. It restores the system clock and BIOS settings when the original cell has failed. The lithium coin cell is intended for motherboard RTC circuits, not for the main laptop battery compartment.

Tested lithium cell with low self-discharge

Each unit is tested before shipping to verify voltage and capacity. The lithium chemistry provides stable voltage over a wide temperature range inside the chassis. Typical current draw is in the microampere range, so the cell contributes negligible heat or noise to the system.

Single battery supplied ready to install

The package includes one CMOS battery without additional cables, brackets or software. No drivers or configuration utilities are required; installation is a simple hardware swap on the motherboard. Buyers who need a main power battery or a multi-cell pack will not find it here.

Highlights

  • Compatible with Fujitsu LifeBook AH530 motherboards
  • Lithium chemistry provides stable CMOS power retention

Questions about this item

How do I install the CMOS battery in my LifeBook AH530, and what step do people often get wrong?

The battery plugs into the motherboard header; the common mistake is reversing the polarity, so match the red and black wires to the board markings before pressing the connector in.

What maintenance or replacement will this CMOS battery need later?

It is a primary lithium cell that cannot be recharged; expect to replace it again in several years when the system clock starts losing time.

What limit shows up first under sustained use of this CMOS battery?

The cell voltage gradually drops until it can no longer keep the real-time clock and BIOS settings alive, at which point the laptop forgets the date on every cold boot.
