What this battery replaces

The KingSener DR02P is a 54Wh 11.4V lithium-ion replacement battery built for Dell Latitude 3340, 3440, 3450, 3540, 3550, 5340, 5440, 5450, 5550 and 7455 models. It also fits Precision 3490, 3580 and Inspiron 14 Plus 7441 systems. The part matches OEM numbers including GRWKG, JTG7N, R73TC and the NKXK7 series.

Voltage and capacity limits

The cell delivers 11.4V and 54Wh, so it only suits laptops designed for that exact voltage and watt-hour rating. Systems requiring a different voltage or a higher capacity pack will not operate correctly with this unit. The black Li-ion pack is a direct swap for the original equipment battery.

The deciding specification

The 54Wh capacity at 11.4V is the single figure that determines compatibility. If the service tag or original battery label shows a different watt-hour value or voltage, this DR02P will not be the right part for that machine.
