How long can a carbon lead battery last?

Carbon lead batteries have a theoretical unlimited charge/discharge rate. Standard lead-type batteries have charge/discharge rates between 5-20% of their rated capacity, meaning you can charge or discharge them between 5 – 20 hours without causing any long term damage.

Why should a negative plate be replaced with a lead carbon composite?

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.
