Replacement Battery for Latitude E-Series

This new aftermarket battery fits Dell Latitude models E5420, E5430, E5520, E5530, E6420, E6420 XFR, E6430, E6430 ATG, E6440, E6520, E6530 and E6540. It replaces part numbers including T54FJ, NRFFP, HCJWT and 312-1163. The unit is designed for owners who need a direct replacement or a spare power source.

Sustained Runtime at 5200mAh

The 6-cell pack delivers 5200mAh at 10.8V to support extended work sessions away from mains power. Capacity is rated for full discharge cycles rather than brief peaks, so the battery maintains output through long meetings or travel. It is not intended for users who require hot-swap capability or secondary-bay expansion.

Voltage and Cell Limits

Operating at 10.8 volts across six cells, the pack conforms to the original electrical specification for the listed Latitude chassis. The fixed cell count and voltage ceiling mean the battery cannot exceed the runtime ceiling set by the laptop charging circuit. Builders needing higher capacity or a different voltage platform will not be served by this part.

Questions about this item

Does the 5200mAh 10.8V pack run hotter than the original 6-cell after a full day of use?

It matches the factory 10.8V 6-cell design, so thermal behaviour stays the same as the original battery under identical workloads.

My Latitude E6430 charges through the round barrel jack — does this pack need a different connector?

No, it uses the same Dell barrel connector as the original T54FJ and NRFFP packs, so your existing AC adapter plugs straight in.

Will the 5200mAh cell fit the older E6420 XFR chassis without a spacer?

Yes, the 6-cell form factor is identical across the E6420 XFR, E6430 ATG and the rest of the listed Latitude models.
