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:
Here is the formula of charging time of a lead acid battery. Charging time of battery = Battery Ah / Charging Current T = Ah / A Where, T = Time hrs. Ah = Ampere Hour rating of battery A = Current in Amperes Example Example based on a 120 Ah battery (This information is available on the label of the battery on the top side)
Charger Current (A): The charger’s output current is typically measured in Amps (A) or milliamps (mA). To consider the current charge level, we multiply the battery capacity by the uncharged percentage. Effective Capacity (Ah) = Battery Capacity (Ah) × (1−Charge Level/100) Let’s say you have:
The charging current refers to the amount of electrical current supplied to the li-ion cell during charging. It’s measured in amperes (A). Typically, li-ion cells are charged at a rate between 0.5C and 1C, where “C” represents the battery’s capacity in ampere-hours (Ah). For example, a 2000mAh battery charged at 1C would use a 2A current.
Standard Charging: Using a standard charger that supplies a typical current (usually around 0.5C to 1C, where C is the battery’s capacity), it takes approximately 2 to 3 hours to charge a Li-ion cell from 0% to 100%. Fast Charging: Some modern chargers can supply higher currents (above 1C), reducing charging time to as little as 1 hour.
Consider Charge Level: The battery is already at 50%, so only 50% of its capacity needs to be charged: Effective Capacity = 2Ah × (1−0.50) = 1Ah Calculate Charging Time: Now, divide the effective capacity by the charger’s current: Charging Time = 1Ah / 1A = 1 hour In this example, it will take 1 hour to charge the battery from 50% to 100%.
