Package Contents and Fit

The box contains one battery only; no tools or cables are included. It matches original part numbers such as 1G9VM GR5D3 M28DH 0FNY7 451-BBSB 451-BBSF and 31CP7 variants. Direct replacement restores factory charging behaviour without extra software.

Capacity and Runtime Limits

The 91Wh rating delivers extended runtime for typical mobile workstation workloads on 15 and 17 inch Precision chassis. Heavy GPU compute or sustained maximum brightness will reduce available hours. The pack is not suitable for systems requiring a different voltage or higher capacity.

Questions about this item

How often will the 91Wh lithium-ion cell need replacement under daily charging cycles?

The 91Wh lithium-ion pack is rated for hundreds of charge cycles; typical users replace it after two to three years when runtime drops below their needs.

What runtime limit appears first when the 11.4V battery powers a Precision 7720 under continuous load?

The 91Wh capacity sets the runtime ceiling; sustained heavy workloads will drain the pack in roughly the same span as the original factory battery.

Does the black MFKVP unit run hotter or louder than the original after hours of all-day use?

The replacement cell produces no fan noise and its thermal output matches the original 11.4V design, so heat and acoustics stay unchanged.
