Compatible replacement for Esprimo Mobile M9400

This DBTLAP CMOS battery is built for the Fujitsu Esprimo Mobile M9400 motherboard. It supplies the low-voltage backup power that keeps BIOS settings and the real-time clock alive when the main battery is removed. The lithium cell arrives tested and ready to install.

Sustained charge retention over years

A CMOS cell does not deliver bursts of current; it provides a steady micro-amp draw for years at a time. This lithium chemistry maintains stable voltage throughout its service life, so the system clock and firmware configuration remain intact across long shutdowns.

Low self-discharge, silent operation

The cell generates no heat and no noise during normal operation. Its minimal self-discharge rate preserves capacity while the laptop is stored or running on main power. Power draw is limited to the tiny trickle the RTC circuit requires.

Questions about this item

How much power does the DBTLAP CMOS battery draw while the Fujitsu Esprimo Mobile M9400 runs all day?

The lithium CMOS battery supplies only a tiny standby current to keep the real-time clock and BIOS settings alive; it does not draw measurable power from the mains while the laptop is running.

What must I already have to install this CMOS battery in the Fujitsu Esprimo Mobile M9400?

You need a small Phillips screwdriver to open the chassis and access the motherboard battery socket; no additional cables, adapters or software are required.

Will this replacement CMOS battery work with the original BIOS firmware on my Fujitsu Esprimo Mobile M9400?

Yes, the battery is a direct lithium RTC replacement, so it maintains CMOS settings and the system clock exactly as the original cell did.
