Below are the formulas for calculating the required battery charging time (in hours) and the necessary charging current (in amperes): Charging Time of Battery = Battery Ah ÷ Charging Current t = Ah ÷ A and Required Charging Current for battery = Battery Ah × 10% A = Ah × 10% Where: t = Time in hrs.
Typical charging current: 0.1C to 0.3C Charging time: 6–12 hours Efficiency: ~80% Typical charging current: 0.5C to 1C Charging time: 1–3 hours Efficiency: ~95% Typical charging current: 0.5C Charging time: 2–4 hours Efficiency: ~90% Tips to Optimize Charging Current and Time
Battery capacity is one of the main variables in calculating Charging Current and Time. Battery capacity is typically expressed in ampere-hours (Ah). For example, a 100Ah battery can theoretically provide 1 amp for 100 hours. The C-rate is a key concept in battery charging.
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. When the batteries are fully charged, the charging current drops to 0.1C.
As a general rule, the maximum charging current of a battery is around 10 to 20% of its entire capacity. For example, if you have a 12V lithium battery with a capacity of 100 Ah, the maximum charging current should not be more than 20 Amps. It is better to speak with your supplier to determine your batteries’ exact maximum ampere rate.
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)
