Replacement battery for Dell Latitude 5320 7320

This 63Wh lithium-ion pack operates at 15.2V across four cells and is built to fit the listed Dell Latitude 13 and 14 series chassis. It ships new from the manufacturer with grade-A cells and carries CE and UL safety certifications. The black housing matches the original appearance and connects through the standard internal cable.

Replaces Dell part numbers 7FMXV 0TN2GY 9JM71

The unit covers Latitude 5320 7320 7420 7520 and 5340 2-in-1 models, including P134G001 P135G001 P138G001 service tags. It is not compatible with the Latitude 7320 detachable laptop, so buyers needing that form factor should look elsewhere. A 12-month warranty backs the replacement.

Straightforward swap with attention to the connector

Power down the laptop, disconnect the old battery from the motherboard, remove the securing screws and fit the new pack in the same bay. If the system does not recognise the battery at first boot, reseat the cable and ensure it is fully seated. Cycle the charge between 10 and 20 percent up to full three or four times to calibrate the fuel gauge.

Questions about this item

Will the 15.2V 4-cell pack fit the Latitude 5320 chassis without modification?

The battery is built to the same 15.2V 63Wh 4-cell form factor used in the Latitude 5320, 7320, 7420 and 7520 series, so it seats in the original bay using the existing screw holes.

Which step in the install guide do people most often miss?

Disconnecting the old battery from the motherboard before removing any screws is the step most frequently skipped; leaving it connected risks shorting the board during removal.

How often should the 63Wh Li-ion pack be cycled to keep capacity stable?

After the initial 3–4 full charge cycles to wake the cells, a full discharge to 10–20% followed by a full recharge every 1–2 months helps maintain capacity.
