Direct replacement battery

The Beisite FPB0278 FPB0285 is a new lithium-ion battery built for Fujitsu Lifebook 552 AH552 AH552/SL notebooks. It matches the original 11.1V 48Wh specification and replaces part numbers FPB0278 and FPB0285. Owners of these models can restore full mobile operation without adapter dependence.

Single unit package

The box contains only the battery itself; no tools, screws, cables or software discs are included. Installation relies on the notebook’s existing latch mechanism, so no extra hardware is required. Buyers who need a charging cable or external charger must source those separately.

48Wh capacity ceiling

At 48Wh the pack delivers typical runtime for everyday office tasks and web browsing on the supported Lifebook 552 series. Heavier workloads such as sustained video encoding or gaming will deplete the charge more quickly. Users who need all-day operation away from mains power should plan for a second battery or a portable power bank.

Questions about this item

When will the FPB0278 FPB0285 battery need replacing?

The 48 Wh lithium-ion cell is rated for hundreds of charge cycles; plan a swap once runtime falls below your daily needs, typically after two to three years of regular use.

What limits the FPB0278 FPB0285 during all-day work?

The 48 Wh capacity sets the runtime ceiling; sustained heavy loads drain the pack faster, so the practical limit is the stored energy itself.

How hot or noisy does the FPB0278 FPB0285 get under continuous load?

The battery has no fan and runs silent; it warms slightly during discharge but stays within normal lithium-ion operating temperatures.
