Replacement battery for select LIFEBOOK models

This new lithium-ion unit replaces the original power pack in compatible Fujitsu LIFEBOOK notebooks. It restores mobile runtime for owners of the listed machines who need a fresh cell. The four-cell design fits the existing battery bay without modification. Buyers with other laptop brands or unlisted LIFEBOOK series cannot use this part.

Voltage and capacity match the OEM specification

The pack delivers 15.12 volts and 4280 milliampere-hours, matching the electrical ratings of the original CP801785-02 and FPCBP592 modules. This single figure confirms the battery will charge and report capacity correctly through the system firmware. A different voltage or capacity would prevent proper operation or cause reporting errors.

Drops into the internal bay

Installation uses the standard latch mechanism inside the chassis; no tools or cable routing are required. Once seated, the notebook regains untethered operation so the charger can stay at the desk. Users who rely solely on wall power or who need a higher-capacity pack than the four-cell design provides will not be served by this unit.

Questions about this item

What does the 4280 mAh rating mean for daily runtime on a LIFEBOOK E4512?

The 4280 mAh capacity at 15.12 V provides the energy reserve the original battery was designed to deliver, matching the factory runtime profile for the E4512.

Does the FPCBP592 use a standard laptop battery connector or a proprietary interface?

It uses the exact proprietary connector and pin-out specified by the OEM part numbers CP801785-02 and FMVNBP253, so it plugs directly into the E4512, E5512 and U7411 without adapters.

Will the 4-cell pack fit the existing battery bay on a LIFEBOOK U7411 without modification?

Yes, the physical dimensions and screw-hole pattern match the original 4-cell design for the U7411, E4512 and E5512 chassis, so it drops into the standard bay.
