Who this suits and who should look elsewhere

It suits owners of the listed Latitude models who need a direct 42Wh replacement for a worn or failed original pack. Buyers whose laptop requires a different voltage or a higher capacity pack should look elsewhere. The unit only covers the specific part numbers and models shown above.

Deciding specification — 42Wh capacity

The single figure that decides fit is the 42 watt-hour rating at 11.4 volts. Confirm your original battery shows the same capacity and voltage before ordering. A different watt-hour value means this pack will not match the runtime or charging profile your laptop expects.

Questions about this item

Does the 11.4 V lithium-ion battery charge through the laptop's standard power connector?

Yes, it connects to the same internal power rail used by the original 0G74G pack in Latitude 7280, 7290, 7380, 7390, 7480 and 7490 models.

Will this pack fit the Latitude 7280 chassis without modification?

The pack matches the original 0G74G form factor and screw-hole pattern for Latitude 12 7280, 7290, 7380, 7390, 7480 and 7490 series.

What is the correct order to install the battery and avoid the common boot-loop?

Disconnect the AC adapter, remove the base cover, unplug the old pack, connect the new 42 Wh unit, refit the cover, then reconnect AC power before first boot.
