Replacement Battery for Dell Detachable

This 40Wh lithium-ion replacement battery operates at 7.6V and delivers 5000mAh capacity for the Dell Inspiron 14 3420 and Latitude 7320 Detachable series. It replaces original codes including 9F4FN, 09F4FN, 8PK6G, 2VKW9, 2ICP4/79/112 and 2ICP4/79/111. The unit is rated for up to 500 recharge cycles over its service life. Buyers who need a higher-capacity pack or a different voltage will not find it here.

Straightforward Internal Swap

Installation requires opening the detachable chassis and disconnecting the existing pack before connecting the new battery. The main difficulty is the adhesive securing the original cell and the fragile ribbon cables around the connector. No soldering or firmware update is needed, but patience and a plastic pry tool help avoid damaging the display assembly.

Steady Output Through a Workday

Under sustained load the 40Wh cell maintains consistent voltage without the sharp drops seen in aged packs. It supports typical office workloads across a full day on a single charge. The chemistry is rated for up to 500 cycles, so capacity loss remains gradual rather than sudden. Users running continuous heavy compute tasks will see shorter runtimes than light-use scenarios.

Questions about this item

How can I verify the 9F4FN battery is working correctly after installing it in my Dell Inspiron 14 3420?

The system should recognise the 7.6V 40Wh pack, show charging progress in the operating system, and run on battery power without unexpected shutdowns.

What comes with the 9F4FN replacement battery and do I need any extra parts for the Dell Latitude 7320 Detachable?

The package contains the 9F4FN Li-ion battery only; no tools, screws or cables are included, so reuse the original hardware from the laptop.
