The higher the charging current, the higher is the capacity restituted. In the same way, energy efficiencies increased with increase in charging current. This then suggests that the choice of charging current is of paramount importance as the charging efficiency of lead acid batteries is concerned.
In this paper, the impact of high constant charging current rates on the charge/discharge efficiency in lead acid batteries was investigated upon, extending the range of the current regimes tested from the range [0.5A, 5A] to the range [1A, 8A].
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. To determine the right charging rate for a new lead acid battery, several factors need to be considered.
This suggests that the efficiency of charge can be ameliorated by using constant charging currents above 2A. So the best range of current magnitudes that can be used to charge this lead acid battery is between 2A and 5A.
Overcharging can cause excessive heat, gas production, and even battery failure. Regularly check the battery’s condition and follow safety precautions to avoid any accidents or damage. Properly understanding and implementing the appropriate charging current for a new lead acid battery is essential for its long-term performance and longevity.
Under the right temperature and with sufficient charge current, lead acid provides high charge efficiently. The exception is charging at 40°C (104°F) and low current, as Figure 4 demonstrates. In respect of high efficiency, lead acid shares this fine attribute with Li-ion that is closer to 99%.
