Buyers with a Latitude 14 5420, Latitude 15 5520 or Precision 15 3560 who need a direct replacement for part numbers RJ40G, 01K2CF, 075X16, 0WK3F1, 0M3KCN or 005R42 will find this battery fits without modification. It is not for users whose original battery carries a different part number or voltage, nor for laptops outside the listed Dell series.

63 Wh capacity decides runtime

The single figure that determines whether this unit meets your needs is the 63 Wh rating at 15.2 V. If your workload demands more stored energy than 63 Wh provides, this battery will fall short. If 63 Wh matches or exceeds the original specification, the pack will deliver the expected runtime.
