COMPARISON NiMH vs NiCd

Comparison

NiMH vs Alkaline

 Today, more and more high drain devices are in the home that consume battery power quickly. Consumers will greatly benefit from the value proposition delivered by NiMH.  Not only do they deliver more power, lasting longer in high drain devices, but they also can be charged up to 1000 times. 

   PERFORMANCE:  NiMH batteries will greatly out-perform standard NiCd batteries in high-drain applications.

   VOLTAGE:  The power produced by the battery. Both NiMH and NiCd have virtually the same voltage.

   CAPACITY:  The amount of energy stored by the battery. NiMH has more than twice the capacity of standard NiCd. This results in much longer runs times (hours, # of pictures).

   MEMORY EFFECT:  NiMH batteries can be charged or “topped-off” at any time without affecting battery life. In order to achieve optimum performance from NiCd batteries, they must be fully discharged before recharging. Unlike NiCd batteries, NiMH has No Memory Effect.

   ENVIRONMENTALLY FRIENDLY:  NiMH batteries have no Cadmium added.  Cadmium is hazardous to the environment.
