Let’s go. In the ideal/theoretical case, the time would be Time (H) = Capacity (Ah)/Current (A). If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). Feel Confused ? So how to calculate how long a battery will last?
Battery charge time is determined by dividing the battery capacity by the charging current, adjusted for efficiency. Whether it’s the robust lead acid battery used in vehicles or the sleek LifePo4 battery in modern electronics, this fundamental principle remains consistent.
Battery charging time is the amount of time it takes to fully charge a battery from its current charge level to 100%. This depends on several factors such as the battery’s capacity, the charger’s voltage output, and the battery charge level. The basic formula used in our calculator is: Charging Time = Battery Capacity (Ah) / Charger Current (A)
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)
If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour. In other words, you can have "any time" as long as when you multiply it by the current, you get 100 (the battery capacity).
As we know that charging current should be 10% of the Ah rating of the 12v battery. This is because a higher rate may cause the battery acid to boil. So charging current for 120Ah Battery = 120 x (10/100) = 12 Amperes Suppose we took 10 Amp for charging purpose, then charging time for 120Ah battery = 120 / 10 = 12Hrs.
