Replacement battery for Dell Latitude and Precision

This 63Wh lithium polymer battery replaces the original RJ40G, 01K2CF, 075X16 and 0M3KCN packs in Dell Latitude 5420, 5520 and Precision 3560 notebooks. It delivers a nominal 15.2V and 3941mAh capacity with a three-cell layout. The unit ships new with a set of repair tools for installation.

Upgrading from a worn or swollen pack

When the original battery no longer holds a useful charge or shows physical swelling, this replacement restores full runtime without requiring a higher-capacity alternative. The jump is worth it when the laptop otherwise meets your workload needs and you want a direct drop-in part that matches the factory voltage and form factor.

Capacity and headroom for daily workloads

Rated at 63Wh and tested for up to 500 charge cycles, the pack comfortably powers typical office applications, web browsing and video playback through a standard workday. It runs out under sustained heavy loads such as continuous rendering or gaming sessions that draw maximum power for extended periods. Buyers needing longer unplugged time than the original design provides will not find that extra margin here.
