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.
