What this battery replaces

The DR02P is a 54Wh lithium-ion pack rated at 11.4V and 4623mAh. It fits Dell Latitude 5340 5440 5540 3340 3440 3540 3480 3580 series and Precision 3480 3490 3580 3590 models. It replaces part numbers DR02P R73TC 2X1V9 0803W6 803W6 and GTG7N GRWKG.

Capacity and everyday headroom

At 54Wh the pack delivers several hours of typical office work on a full charge. Heavy workloads such as sustained compiles or video export will drain it faster, so users who need all-day runtime without a charger should plan for a mid-day top-up.

Thermals noise and power behaviour

The battery runs cool during normal charging and discharging cycles. No fan or moving parts are present, so operation is silent. The 11.4V output matches the original specification, ensuring stable power delivery without extra stress on the laptop charging circuit.

Questions about this item

Will the 11.4 V 54 Wh DR02P fit my existing Dell Latitude 5550 without any chassis modifications?

The DR02P is listed as compatible with the Latitude 5550 series and matches the original 11.4 V 54 Wh specification, so it installs in the same battery bay.

How can I verify the new DR02P is charging correctly after I install it?

After fitting the battery, power on the laptop and confirm the OS reports 11.4 V and a rising charge percentage; run a full discharge to 5 % then recharge 3–4 times to calibrate the fuel gauge.

What exactly ships with the DR02P and do I need to buy any extra parts?

The package contains one DR02P battery and one instruction manual; no cables, screws or tools are included.
