A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
the ideal current or amps to charge a car battery are 20% of its full capacity e.g 10 amps for a 50Ah battery the ideal charging current for a 12v 7ah battery is 1.4 amps maximum charging current for 100Ah battery should not be above its 20% of full capacity (20 amps)
Battery Capacity (Ah): The rated capacity of the battery in ampere-hours. This value is typically provided by the battery manufacturer and represents the amount of charge the battery can hold. Charging Current (A): The current provided by the charger, measured in amperes. This value is often specified on the charger itself.
The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.
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:
As a rule of thumb, the minimum amps required to charge a 12v battery is 10% of its full capacity but the ideal charging current should be between 20-25% of the battery's capacity For example. if you have a 12v 100Ah battery then you'll need a minimum of 10 amps and a maximum of 20-25 amps to recharge your battery
