Replacement battery for Latitude 5420 5520

This 15.2V 63Wh lithium-ion unit replaces Dell part numbers RJ40G 01K2CF 075X16 WY9DX 0WK3F1 0M3KCN 005R42. It fits Latitude 5420 5520 and Precision 3560 series notebooks. Buyers who need the 42Wh variant instead should verify their original battery before ordering.

Capacity and runtime headroom

The 63Wh 3941mAh pack delivers a full day of typical office work on a single charge. Heavy workloads such as sustained rendering or virtual machines will drain it faster. Users who require longer unplugged sessions may need to carry a spare or use a USB-C power bank.

Connector match and daily handling

The connector layout varies between production batches so the installer must compare the photo with the original battery before fitting. If the laptop does not recognise the pack at first boot, reseat the cable and cycle the charge from 5 percent to full three or four times. The cell carries CE RoHS FCC marks and is backed by a 12-month manufacturer warranty.

Questions about this item

Will the RJ40G 63Wh battery fit my Dell Latitude 5420 if I currently use the 42Wh WY9DX model?

No, the RJ40G 63Wh and WY9DX 42Wh are different batteries for the Latitude 5420 and 5520. You must match the part number on your original battery before ordering.

How do I know the RJ40G battery is working correctly after I install it in my Precision 3560?

If the battery is not recognised at first, reseat the connector fully. Then discharge to 5 percent, charge fully, and repeat 3 to 4 cycles to condition the new pack.

Does the box for the RJ40G include any tools or cables, or is it just the battery?

The package contains only 1 RJ40G battery. No tools, cables or adapters are included.
