Replacement battery for Latitude 2-in-1 models

This 15.2 V lithium-ion pack delivers 63 Wh and 3941 mAh across four cells. It replaces part numbers 7FMXV, 0TN2GY, TN2GY, 9JM71, 4M1JN, 1PP63, HDGJ8 and MHR4G. The unit fits Dell Latitude 5320, 7320, 7420 and 7520 series, including the 5320 2-in-1, 7320 2-in-1 and 7420 2-in-1 variants. It does not fit the Latitude 7320 Detachable. Buyers who need a battery for that detachable model cannot use this part.

Sustained operation and cycle life

Built-in circuit protection guards against overcharge, over-discharge and short circuits during extended use. The pack is rated for more than 500 recharge cycles over its service life. Safety certifications include CE, UL, FCC and RoHS. Users who require a higher cycle count or a different chemistry will need to select an alternative.

63 Wh capacity decides fit

The 63 Wh rating determines whether this battery matches the original specification for the listed Latitude systems. Verify the original battery model inside the chassis before ordering. If the existing pack shows a different watt-hour value or a different part number, this unit will not be compatible.

Questions about this item

Does the 7FMXV 15.2V 63Wh battery generate noticeable heat during all-day use?

The 7FMXV is a passive Li-ion pack with no moving parts, so it produces no fan noise and only minimal warmth under normal load. Built-in circuit protection keeps temperatures stable during extended sessions.

What must I already own to install this 4-cell 3941mAh replacement battery?

You need a compatible Dell Latitude 5320, 7320, 7420 or 7520 series 2-in-1 (excluding the 7320 Detachable), a Torx or Phillips screwdriver for the back cover, and the original Dell charger for proper charging.

Will the 7FMXV 0TN2GY replacement work alongside the original motherboard and charging circuit in my older Latitude 7420 2-in-1?

Yes. The 7FMXV matches the 15.2V 63Wh spec and part numbers 0TN2GY, TN2GY, 9JM71, 4M1JN, 1PP63, HDGJ8 and MHR4G, so the existing motherboard and charger recognise it without modification.
