Questions about this item

How do I install the FPB0357 battery in my LIFEBOOK CH75/E3?

Power off the laptop, disconnect the AC adapter, release the old pack using its latch, align the FPB0357 with the connector and press until it locks, then reconnect power.

What replacement will the FPB0357 need after the 12 month warranty period?

The 15.44V 53Wh Li-ion cell will eventually hold less charge; when runtime drops below your needs, purchase another FPB0357 or compatible 4ICP5/39/108 pack.

What is the first limit I hit when running the FPB0357 continuously on a CH90/E3?

The 53Wh capacity sets the runtime ceiling; under sustained load the battery depletes until the laptop forces a shutdown or you reconnect the AC adapter.
