Compatible CMOS Battery for Fujitsu Amilo Mini Ui

This DBTLAP lithium CMOS battery replaces the BIOS RTC cell on the Fujitsu Amilo Mini Ui 3520 motherboard. It is a dedicated coin-cell component, not a main laptop power pack. The unit arrives new and tested, ready to restore system clock and BIOS settings when the original cell fails.

Sustained Reliability Under Continuous Operation

The lithium chemistry delivers a stable voltage over the multi-year lifespan typical of CMOS duties. It maintains the real-time clock and firmware configuration without drift during long periods where the notebook is unplugged or stored. No recharge cycles are involved, so capacity fade is limited to the slow self-discharge inherent to the cell type.

Straightforward Motherboard Installation

Replacement requires opening the chassis to access the motherboard socket, then unclipping the old cell and pressing the new one into place. Polarity is keyed, but builders should still verify orientation against the board markings before seating the battery. The most common issue is forgetting to reset the BIOS time and boot order after the swap.

Questions about this item

How much power does this lithium CMOS battery draw while the Fujitsu Amilo Mini Ui 3520 runs all day?

The CMOS battery only supplies a tiny standby current to keep the real-time clock and BIOS settings alive; it does not power the laptop during normal operation.

What must I already have inside the Fujitsu Amilo Mini Ui 3520 for this replacement to work?

You need the original coin-cell socket on the motherboard that accepts a standard lithium CMOS cell.

Will this DBTLAP cell fit the same motherboard header used by the original battery in my Amilo Mini Ui 3520?

Yes, it is built as a direct replacement for the factory CMOS battery in that model.
