Lead carbon: 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 isimprovedcycle life.
Tests have shown that lead carbon batteries do withstand at least five hundred 100% DoD cycles.
The tests consist of a daily discharge to 10,8V with I = 0,2C₂₀, followed by approximately two hours rest in discharged condition, and then a recharge with I = 0,2C₂₀
Cycle life
- more 500 cycles @ 100% DoD (discharge to 10,8V with I = 0,2C₂₀, followed by approximately two hours rest in discharged condition, and then a recharge with I = 0,2C₂₀)
- more 1000 cycles @ 60% DoD (discharge during three hours with I = 0,2C₂₀, immediately followed by recharge at I = 0,2C₂₀)
- more 1400 cycles @ 40% DoD (discharge during two hours with I = 0,2C₂₀, immediately followed by recharge at I = 0,2C₂₀)
