Compatible Replacement Battery

The E-buy 50Wh Li-ion pack replaces part numbers FPB0340S and FPCBP536 for Fujitsu LifeBook U937 U938 U939 U939X and U9310 U9310X series notebooks. It delivers 14.4V and 3490mAh capacity in a black housing. The unit is supplied new with a six-month warranty.

Straightforward Swap Installation

The battery sits in the standard service bay so removal of the bottom cover and a few screws is all that is required. Align the connector carefully because the keyed plug only seats one way. Forcing the cable or forgetting to reconnect the screw bosses are the most common errors that prevent the pack from being recognised.

Ideal for Mobile Professionals

This pack suits owners of the listed LifeBook ultraportables who need a fresh power source for daily travel. Users whose chassis has a different part number or who require a higher-capacity cell should look at something else. Builders working on non-Fujitsu models will find no fit here.

Questions about this item

How can I confirm the 50Wh Li-ion battery is charging correctly after installing it in my LifeBook U937?

After installation the Fujitsu BIOS should report the 14.4V pack at its full 3490mAh design capacity and the OS battery meter should rise steadily while the AC adapter is connected.

What comes with the FPB0340S battery and what must I supply myself for the LifeBook U938?

The box contains only the new 50Wh Li-ion battery in black; you must reuse the existing screws and thermal pads from the old pack and provide a compatible Fujitsu AC adapter for charging.

Which replacement part number matches my LifeBook U939X — FPB0340S or FPCBP536?

Both FPB0340S and FPCBP536 refer to the same 50Wh 14.4V battery and are listed as direct replacements for the U939X series.
