![]() Voltage pulses will be applied on a commercial automotive battery to collect data, using a charger/Desulfator prototype based on a PCDUINO. In this paper, we study the effects of the recovery capacity of a Lead Acid Battery. Voltage pulse decompose the sulfate (PbSO4) attached to the electrode which is the main cause of the loss of capacity. A motor in idle or at low speed cannot charge the battery sufficiently. This is common with starter batteries in cars driven in the city with a load-hungry accessory. This phenomenon appears naturally at each discharge of the battery, and disappears during a recharge. ![]() Sulfation represents the accumulation of lead sulfate on the electrodes (lead plates). 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. This paper studies the impact of Pulse Voltage as Desulfator to recover weak automotive Lead Acid Battery capacity which is caused by Sulfation.
