This paper studies the impact of Pulse Voltage as Desulfator to recover weak automotive Lead Acid Battery capacity which is caused by Sulfation. This technique is used to overcome the premature loss of battery capacity and speed up the process of charging and extend the lead acid battery life cycle 3 to 4 times compared with traditional charging methods using constant current. Sulfation represents the accumulation of lead sulfate on the electrodes (lead plates). This phenomenon appears naturally at each discharge of the battery, and disappears during a recharge. This is common with starter batteries in cars driven in the city with a load-hungry accessory. A motor in idle or at low speed cannot charge the battery sufficiently. Voltage pulse decompose the sulfate (PbSO4) attached to the electrode which is the main cause of the loss of capacity. In this paper, we study the effects of the recovery capacity of a Lead Acid Battery. Voltage pulses will be applied on a commercial automotive battery to collect data, using a charger/Desulfator prototype based on a PCDUINO. The experiment results show that there is improvement of Cold Cranking Amps level, and charge time duration of the Lead Acid Battery after using our prototype.
