Lead carbon offers 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.
Tests have shown that Victron lead carbon batteries withstand at least five hundred 100% DoD cycles. The tests consist of a daily discharge to 10,8V with I = 0.2Cāā, followed by approximately two hours rest in discharged condition, and then a recharge with I = 0.2Cāā.
