Replacement battery for Dell Precision mobile

This 6-cell lithium-ion unit delivers 97 Wh at 11.4 V and fits Dell Precision 7530 7730 7540 7740 series notebooks. It replaces part numbers 0WMRC GW0K9 0NYFJH NYFJH P34E P34E001 P34E002 P74F P74F001 P74F002. The battery is new from the manufacturer and carries a one-year warranty.

What the package adds

The box contains only the battery itself; no tools, screws or software are included. The supplier advises opening the laptop case to verify the original battery shape and part number before ordering because a 64 Wh alternative also exists for these models. A break-in routine of discharging to 5 % then charging for three to four cycles is recommended to wake up the cells.

Who this suits and who should look elsewhere

This unit suits owners of the listed Precision workstations who need a direct 97 Wh replacement and can confirm their current battery matches the NYFJH form factor. It is not for users whose laptop requires the 64 Wh variant or a different physical layout, nor for anyone needing installation accessories or multi-pack bundles.

Questions about this item

How often will the 6-cell 97Wh Li-Ion pack need replacing?

The battery is rated for 97 Wh at 11.4 V using six Li-Ion cells; Dell does not publish a cycle-life figure, so replacement timing depends on individual charge habits and workload.

What stops the NYFJH 97Wh battery from running longer on a heavy workload?

The 97 Wh capacity and 11.4 V output set the energy ceiling; sustained high-power draw from Precision 7530 7540 7730 7740 components will hit that limit first.

How much heat or fan noise does the 11.4 V 97Wh pack add during all-day use?

The pack itself has no fan and generates only normal Li-Ion warmth; any extra heat or noise comes from the laptop's cooling system responding to the workload.
