Replacement Battery for Dell 2-in-1 Devices
This 40Wh 7.6V rechargeable battery replaces the original 9F4FN cell in Dell Latitude 7320 Detachable and Inspiron 14 3420 series systems. It fits the 2-in-1 form factor and restores mobile power for daily work, learning and play. The black pack is brand new from the manufacturer.
Limits of the 7.6V 40Wh Design
Capacity is fixed at 40 watt-hours, so runtime scales directly with the device's power draw and cannot be extended without a larger pack. The 7.6V nominal voltage matches the original specification; the battery management system handles short-circuit, overheat and overload protection within those electrical boundaries.
Upgrading from a Depleted Original Cell
This unit replaces a worn-out factory battery that no longer holds a useful charge. The jump is worth it when the original cell delivers significantly reduced run time or triggers unexpected shutdowns. It is not for users who need higher capacity than the original 40Wh design provides.
