Lead Carbon Battery
Better partial state-of-charge performance, more cycles, and
higher efficiency.
Replacing the active material of the negative plate by a lead
carbon composite potentially reduces sulfation and improves
charge acceptance of the negative plate.
The advantages of lead carbon therefore are:
Less sulfation in case of partial state-of-charge
operation.
Lower charge voltage and therefore higher efficiency and
less corrosion of the positive plate.
And the overall result is improved cycle life.
