What it is and who it fits

This 91 Wh lithium-ion battery replaces the original MFKVP pack in Dell Precision 15 7510 7520 and Precision 17 7710 7720 mobile workstations. It also fits the Precision M7510 and M7710 series. The nine-cell design operates at 11.4 V and comes in a black housing.

Sustained load behaviour

A 91 Wh rating means the pack can deliver its rated voltage across a full workday of CAD rendering or simulation tasks without the voltage sag seen in lower-capacity cells. The nine-cell layout spreads current draw evenly, keeping thermals stable during long compile cycles or GPU compute runs.

Upgrade context and when it matters

This unit replaces batteries carrying part numbers 451-BBSB, 451-BBSF, GR5D3, 1G9VM, M28DH, T05W1, 0FNY7 or TWCPG. The jump is worthwhile when the original pack no longer holds enough charge for a full meeting circuit or when the system throttles because the aging cells cannot sustain peak current.
