 Cadmium is considered as a hazardous material. It is in general considered more poisoned than Lead and there exist less recycling possibilities for Ni Cad batteries, than for Lead Acid batteries.

 One major difference between nickel iron and Ni Cad batteries is discharge rate. Nickel iron batteries cannot deliver the extremely high currents that Ni Cad batteries can, so if heavy loads are used, a larger capacity battery bank has to be employed. On the other side NiFe batteries do not suffer from the memory efferct, which is affecting the Ni Cad batteries.

 One of the most interesting aspects of nickel iron batteries is that they are made without toxic lead or cadmium, which solves a future disposal problem.

 Are the non rechargeable batteries, this means the internal reaction occurs only in one direction therefore the battery life time ends after one cycle.The advantage of this type of batteries is that they have a high energy density. Carbon-zinc batteries and alkaline batteries are the most common types.
