Several factors, including the battery capacity and charging rate, affect the battery charging current. The larger the battery capacity, the higher the charge current typically is. Likewise, the higher the charging ratio, the higher the charging current and the shorter the charging time.
Recommended and Optimal calculation formula simple: battery power (Ah)/ ten (number of hours needed to charge) = strength charge current (Ampere). Example: the battery power is 60A / h, then 60A / h is divided by 10 and we get a charging current of 6A. We set the amperage to 6A on the charger and charge it for about 10 hours. 5.
– It is recommended that the charging current be equal to one tenth of the capacity (e.g. 44Ah divided by 10 = 4.4A charging current). – The temperature of the acid may not exceed 55°C during charging. If the temperature rises above 55°C, the charging process must be discontinued.
When a battery is fully charged, the charging current drops to 0.1C. The circuit switches to constant voltage charging mode once the voltage achieves its maximum, charge cut-off voltage. The charging current of the battery steadily lowers down, and the charging rate slows down when the voltage is sustained at charge cut-off voltage.
The charging current for the battery is 10A±10% or 7.5A±10% or 5A±10% or 4A±10% or 3A±10% or 2A±0.3A or 1.5A±0.3A. The Maxxlee BCS0227 Smart Battery Charger is compatible with 12V & 24V lead-acid batteries (WET, MF, AGM and GEL).
Charging Time of Battery = Battery Ah ÷ Charging Current T = Ah ÷ A and Required Charging Current for battery = Battery Ah x 10% A = Ah x 10% Where, T = Time in hrs. Example: Calculate the suitable charging current in Amps and the needed charging time in hrs for a 12V, 120Ah battery. Solution: Battery Charging Current:
