Charging current plays a significant role in the overall health and performance of a lead acid battery. The charging process involves converting electrical energy into chemical energy within the battery cells. The appropriate charging current ensures that the battery receives the necessary energy without causing damage or premature wear.
The larger the electric charging currents, the greater the effective energy stored. Larger charging current rates provoke higher temperature increases in older than newer batteries. The charging and discharging of lead acid batteries using Traditional Charge Controllers (TCC) take place at constantly changing current rates.
