Questions about this item

Will the 6-cell 10.8 V 58 Wh pack fit the existing battery bay on my ProBook 4530s without modification?

The battery is a direct replacement for the PR06 6-cell module used in the ProBook 4530s and matches the original bay dimensions exactly.

Which screw or latch step do installers most often miss when swapping the PR06 battery on a ProBook 4431s?

After sliding the pack in, the spring-loaded latch must click fully into the locked position; many users stop at the first detent and the battery stays loose.

How many full charge cycles can I expect from the 5200 mAh lithium-ion cells before capacity drops below 80 %?

The cells are rated for up to 500 charge and discharge cycles while maintaining usable capacity.
