Advanced Lead-carbon Added on Negative Electrode:

The historical weakness of lead acid batteries has been their poor performance (low charge acceptance) due to the formation of sulfation crystals. Partial state of charge and battery aging are the two villains attacking the negative plate. Adding carbon on the pure lead neg electrode, turn off damage from partial state of charge and turn on higher charge acceptance. This means the PLH+Carbon can recharge as fast as it can be discharged.
