Check part number before ordering

Verify that the original battery carries the exact part number GRWKG, DR02P, JTG7N, R73TC, 0NKXK7, NKXK7, 0V7TXF or V7TXF. The GRWKG and DR02P families cannot be swapped with each other, so matching the printed code is essential for a correct fit.

This unit replaces Dell P38F, P38F001, P28F, P28F004, P170G, P170G001, P170G002, P170G003, P37G, P37G004, P169G, P169G001, P51G, P51G001 and related part numbers. The upgrade is worth it when the original pack no longer holds a usable charge.

Questions about this item

Does the KingSener GRWKG battery ship with any cables or tools, or must they be purchased separately?

The battery is supplied as a standalone unit; no cables, screwdrivers or installation kits are included.

How do I choose the correct version when multiple Dell part numbers such as P38F, P28F and P170G are listed?

Match the exact part number printed on your original battery — GRWKG, DR02P, JTG7N, R73TC, 0NKXK7, NKXK7, 0V7TXF or V7TXF — because these models cannot be swapped.

What does the 42Wh 11.4V rating mean for daily runtime in a Latitude 5450?

The 42 watt-hour capacity at 11.4 volts delivers the same energy as the original Dell battery, providing a like-for-like runtime under identical workloads.
