91Wh Lithium-Ion Battery for Precision Workstations

This 91Wh lithium-ion battery replaces the original power source in Dell Precision 7510 7520 7710 7720 M7510 M7710 models. It uses premium four-cell construction rated at 11.4V to restore full mobile operation. The unit is CE and RoHS certified for safety and environmental compliance. Buyers who need a different voltage or cell count cannot use this pack.

Sustained Output Behaviour

The four-cell lithium-ion design delivers a steady 11.4V supply throughout the discharge cycle rather than a brief peak. Consistent voltage lets the workstation maintain processor and graphics clocks during long rendering or simulation sessions. Capacity remains stable across repeated charge cycles thanks to the premium cell selection. Users who require hot-swap capability or modular bay mounting will find this pack does not support those features.

Interface and Fit Constraints

The battery connects through the Precision series proprietary connector and matches the original chassis footprint exactly. Two distinct battery variants exist for these model numbers and they are not interchangeable, so physical comparison with the original unit is essential before installation. No adapters or alternative mounting options are included. Systems outside the listed Precision range cannot accept this battery.

Questions about this item

Does the 91 Wh battery run cooler during all-day workloads on a Precision 7710?

The 91 Wh lithium-ion pack draws the same 11.4 V as the original, so thermal output matches the factory design during extended use.

What must I verify on my current battery before ordering this MFKVP unit for a Precision 7520?

Compare the physical layout and connector of your existing pack with the product photos; there are two incompatible variants for these models.

Will the 91 Wh replacement fit a Precision M7510 that still uses the original chassis?

Yes, it is listed as 100 % compatible with the M7510 and shares the same 11.4 V, 91 Wh specification as the factory battery.
