7146W 78Wh Li-ion battery for Latitude

The Beisite 7146W is a new 11.4V lithium-ion replacement battery rated at 78Wh. It is built to fit Dell Latitude 7400, 7260, 7270 and 9410 series laptops, including the 2-in-1 variants. The pack replaces part numbers such as NF2MW, 0C76H7 and the wider list of OEM codes supplied by the manufacturer. It ships as a single black unit ready for installation.

Suits owners of listed Latitude models needing

This battery targets users whose original pack no longer holds a useful charge and who own one of the exact Latitude series named above. It is not for owners of other Dell lines, different Latitude generations or non-Dell hardware. Buyers who need a higher capacity than 78Wh or a different voltage should look at something else. The 12 month warranty covers defects but does not extend to damage caused by incorrect fitment.

Simple internal swap; verify part number before

Installation requires opening the laptop chassis, disconnecting the old pack and connecting the new one using the existing cable. Most Latitude designs secure the battery with a few screws and a ribbon connector. What usually goes wrong is ordering without matching the full part-number list — NF2MW, 0C76H7, 0G8F6M and the rest — leading to a physical or electrical mismatch. Check the sticker on your original battery against the supported codes before fitting.

Questions about this item

Does the 7146W battery install in a Latitude 7400 2-in-1 without any extra cables or brackets?

The 7146W is a direct replacement for part numbers NF2MW and 0C76H7 and fits the Latitude 7400 and 7400 2-in-1 chassis using the existing battery bay and connector.

Will the 11.4 V 78 Wh pack charge correctly on a Latitude 7260 that originally used a lower-capacity battery?

The 7146W matches the 11.4 V specification and is listed for Latitude 7260 and 7270 models, so the system's charging circuit will recognise and charge it normally.

How can I verify the 7146W is delivering its rated 78 Wh after the first few charge cycles?

Run a full charge, then use the built-in battery report or a hardware monitor to confirm the design capacity reads 78 Wh and the full-charge capacity is close to that value.
