Replacement Battery for Dell Latitude and Vostro

This lithium-ion battery supplies 5200mAh at 11.1V across six cells. It fits Dell Latitude and Vostro models including 7420, E6540, E6440, E5530, E5430, E6520, E6420 and N3X1D. The unit is new and ready to install.

Direct Swap for Multiple Part Numbers

The pack replaces original Dell part numbers such as 2P2MJ, T54FJ, 12-1325, 312-1165, M5Y0X, PRV1Y and 8858X. Because one physical battery covers many part codes, the label cannot list every compatible number. Email support is available around the clock for fitment questions.

Suitable for Restoring Mobility on Supported Laptops

Typical run time is around two to three hours depending on workload and power settings. Buyers who need longer unplugged sessions or whose laptop model is not in the compatibility list should look at higher-capacity alternatives.

Questions about this item

When will the 5200mAh 6-cell Li-ion pack need replacement?

Capacity fades after several hundred charge cycles; expect shorter runtimes once the battery no longer holds enough charge for your daily workload.

What limits sustained use of the 11.1V battery in a Latitude E6420?

The pack delivers roughly 2-3 hours per charge; actual time drops when the laptop draws more power for bright screens, heavy CPU loads or attached peripherals.

How much heat or noise does the replacement battery produce during all-day operation?

The battery itself is silent and generates only mild warmth; any fan noise or heat you notice comes from the laptop's own cooling system under load.
