These batteries are a disapointment but will have to investagate further.
Ni-MH
The negative electrodes use a hydrogen-absorbing alloy instead of cadmium (nickel–cadmium cell (NiCd).) NiMH batteries can have two to three times the capacity of NiCd batteries of the same size, with significantly higher energy density, although much less than lithium-ion batteries.
