Note: This page covers the NiMH packs of three Prius generations. They share the published voltage and module count, but no source confirms the packs are interchangeable between generations. Check the label.

Note: Sources disagree on the capacity: most give about 1.3 kWh, but ADAC lists the gen 3 at 1.0 kWh, and Green Car Reports gives 1.2 kWh for the US gen 4 NiMH pack.

Note: In the US, most gen 4 grades had a lithium-ion pack instead. UK and EU gen 4 cars have the NiMH pack.
