Direct replacement for Dell Latitude and Precision

This 4-cell lithium-ion battery fits Dell Latitude 5520, Latitude 5420 and Precision 3560 models. It matches OEM part numbers RJ40G, M033W and 75X16. The pack delivers 15.2V and 3941mAh capacity. It is suited for owners restoring original runtime to these laptops.

Drops into the existing battery bay

No adapter, cable or firmware update is required; the pack seats in the factory compartment and connects to the stock connector. The 4-cell layout keeps the original form factor, leaving all ports, vents and drive bays unchanged. Installation is a simple swap that frees the machine from a wall outlet.

Replaces a worn or failed original pack

The upgrade is worthwhile when the current battery no longer holds a useful charge or shows swelling. It restores the mobility the system was designed for. It is not for users needing a higher-capacity alternative or a different voltage configuration.

Questions about this item

How long will the 3941mAh capacity last under sustained load before the 15.2V output drops?

The 4-cell lithium-ion pack is rated at 3941mAh and 15.2V; actual runtime depends on the laptop's power draw, but the capacity figure is the baseline for any sustained-use estimate.

Does the battery run hot or make noise when the laptop is used all day?

Lithium-ion cells generate some heat during discharge, but the pack has no moving parts so it is silent; normal operating temperatures are managed by the laptop's own cooling system.

Which Dell part numbers must my laptop already use for this battery to fit?

It replaces OEM part numbers RJ40G, M033W and 75X16 and fits Dell Latitude 5520, Latitude 5420 and Precision 3560 models.
