Replacement battery for Dell Precision 15

This 91Wh lithium-ion pack replaces the original MFKVP unit in Precision 7510, 7520, 7710, 7720, M7510 and M7710 models. It ships new with a 12-month warranty and matches the factory voltage of 11.4V. The black casing fits the existing battery bay without modification.

Voltage and capacity match the original 11.4V 91Wh

The single figure that decides fitment is the 11.4V 91Wh rating, which equals the OEM design for the listed Precision series. Cross-referenced part numbers include 1G9VM, GR5D3, M28DH, 0FNY7, 451-BBSB and 451-BBSF. A different voltage or watt-hour value would prevent correct charging and runtime.

Restores full-day mobile workloads on supported

At 91Wh the pack delivers the same capacity the workstation was engineered for, handling typical office, CAD and simulation sessions away from mains power. Runtime drops when sustained GPU or CPU loads push the platform beyond the battery's current limit, so extended render farms or compute clusters still need AC supply.

Questions about this item

How long will the 91 Wh rating actually run a Precision 7510 under typical workloads?

The 91 Wh capacity matches the original factory specification, so runtime should be equivalent to a new Dell battery in the same Precision 15 7510 or 7520 system.

Does the 11.4 V output work with the Precision 7720 charging circuit without modification?

Yes, 11.4 V is the exact voltage Dell specifies for Precision 15 7510, 7520, 17 7710 and 7720 models, so the laptop's charging controller accepts it directly.

Will this pack fit the M7710 chassis without any bracket changes?

The battery is built to the 31CP7/60/64-2 form factor used across Precision 15 7510, 7520, 17 7710, 7720, M7510 and M7710, so it seats in the existing bay with no extra hardware.
