Compatible Dell Precision models

This 11.4 V lithium-ion battery fits Dell Precision 15 7510, 7520 and Precision 17 7710, 7720 workstations. It replaces OEM part numbers MFKVP, 0V48RM, V48RM, RDYCT, TWCPG, 451-BBSD and T05W1. The nine-cell pack delivers 91 Whr at 7982 mAh capacity.

Upgrade from lower-capacity packs

Owners replacing a worn six-cell or lower-watt-hour battery will gain longer runtime between charges. The jump is worthwhile when the original pack no longer holds sufficient charge for a full work session or when the laptop shuts down under load.

Verify part number and voltage

Confirm the existing battery carries one of the listed OEM numbers before ordering. Ensure the system voltage label reads 11.1 V or 11.4 V, as mismatched voltage can prevent charging. This unit is not suitable for Precision models outside the 15-inch 7510/7520 or 17-inch 7710/7720 lines.

Questions about this item

What dimensions and connector does the 9-cell 11.4 V battery need to fit a Precision 7510 or 7720?

The pack is built to the 9-cell Dell form factor used in Precision 15 7510, 7520 and Precision 17 7710, 7720 models and uses the original Dell connector that matches OEM part numbers MFKVP, 0V48RM, V48RM, RDYCT and TWCPG.

Which screws and cable routing steps are required when installing the 7982 mAh pack in a Precision 7710?

Remove the bottom case screws, disconnect the old battery cable, lift the 9-cell module out, seat the new pack in the same bay, press the connector firmly until it clicks, then replace the case screws in the original order.

How often should the 91 Whr lithium-ion unit be calibrated to keep the fuel gauge accurate?

Run a full charge–discharge–charge cycle about once every three months; the onboard protection circuit handles daily balancing automatically.
