Replacement battery for Dell Latitude 5320 7320

This 15.2V lithium-ion battery replaces the original 7FMXV unit in Dell Latitude 5320, 7320, 7420 and 7520 series notebooks. It is a new component built to match the factory voltage and form factor. Install it to restore mobile power when the original cell no longer holds a charge.

63Wh capacity at 15.2V

The single figure that decides fit is the 63 watt-hour rating delivered at 15.2 volts, which equals 3941 milliampere-hours. This matches the OEM specification listed under part numbers 7FMXV, 0TN2GY, TN2GY, 9JM71, 4M1JN, 1PP63, HDGJ8, MHR4G, 727CG, 0727CG, CN-0TN2GY and CN-0727CG. If your service tag calls for a different watt-hour value this unit will not be correct.

UL CE FCC RoHS certified safety

The pack carries UL, CE, FCC and RoHS certifications covering electrical safety and restricted-substance compliance. These marks mean the cell has passed independent testing for stable current delivery and low self-discharge. No software or extra accessories are bundled; the certification itself is the assurance that the replacement meets baseline safety and environmental standards.

Questions about this item

What runtime can I expect from the 63 Wh rating in a Latitude 7420?

The 63 Wh capacity matches the original Dell specification, so real-world runtime will be comparable to the factory battery when new.

Does the 15.2 V output work with the Latitude 5320 charging circuit?

Yes, 15.2 V is the exact voltage Dell specifies for these models, so the laptop's charging controller will accept it without modification.

Will this pack fit the internal bay of a Latitude 7520 without adapters?

It is built to the 7FMXV form factor used across the 5320, 7320, 7420 and 7520 series, so it seats directly in the stock battery compartment.
