Differences between NiMH and NiCd:-

  • NiMH batteries have higher energy density which means long run time .It also doesn’t suffer from memory effect. It will last longer.
  • NiMH batteries do not have the capacity to take a higher rate of charge or discharge while NiCd
  • High rate chargers and peak detection can be used to charge NiCd, whereas NiMH batteries do not go well with high rate chargers.
