42 Wh Battery for Dell Latitude 7470 7270

This 42 Wh lithium-ion battery replaces the original power source in Dell Latitude 7470, 7270, E7470 and E7270 series notebooks. It is built for professionals who need reliable mobile power during a full working day. The three-cell pack delivers 11.4 V output and carries CE and RoHS certification.

Voltage and cell count match

The critical specification is the 11.4 V rating combined with a three-cell 42 Wh design. Dell uses two physically different batteries for these chassis codes and they are not interchangeable. Confirm that the original battery shows the same voltage and cell layout before ordering.

Straightforward swap with one catch

Installation requires removing the bottom case screws and disconnecting the old pack, a process that takes minutes with a small Phillips driver. The common error is ordering the alternative battery variant used in the same model family; comparing the part number and connector orientation against the product photos prevents a mismatch.
