The article shows that using Pulse Voltage can help improve the capacity of weak automotive Lead Acid Batteries affected by Sulfation. This technique can extend the battery's lifespan and speed up the charging process compared to traditional methods. By applying voltage pulses to the battery, the sulfate buildup on the electrodes can be broken down, leading to better performance. The study found that using this method increased the Cold Cranking Amps level and reduced the charging time of the Lead Acid Battery, showing promising results for battery recovery.
