The time it takes to charge a battery depends on a few things, like how much power the battery can hold, how fast you’re charging it, and how efficiently the charging process works. To figure out the time it’ll take to charge a battery, you can use this formula: Charging time = (Battery capacity) / (Charging current)
This value should be between 0 and 100. Click the “Calculate” button to get the results. The calculator uses the following steps to determine the battery charge time: Converts Battery Capacity (mAh) to Watt-hours (Wh) using the formula Battery Capacity (Wh) = (Battery Capacity (mAh) * Battery Voltage (V)) / 1000.
Based on your battery being a lithium battery and the charge rate being relatively slow, you assume a charge efficiency of 95%. With that, you can plug your values into Formula 2. In this example, your estimated charge time is 8.42 hours. Using Formula 1, we estimated this same setup to have a charge time of 8 hours.
The time required to charge a battery pack based on its capacity (Wh, kWh, Ah, or mAh) and the charging current (A or mA). Charging Current The current supplied by the charger to charge the battery pack. Current State of Charge (SoC) The current charge level of the battery pack as a percentage.
The battery will get a full charge in: 50/6 = 8.3 hours Example 2: A 720 Wh, 12 V car battery is connected to a charger whose charge rate current is 6 amps. If the battery is at 0%, how long will it take before it gets a full charge? In this example, the battery capacity is in Wh while the charge rate current is in amps (A).
Imagine a smartphone with a battery capacity of 3,000mAh (3Ah). Using a standard charger that delivers a current of 1A, the basic formula suggests it would take 3 hours to charge. However, considering charging efficiency (let’s assume 90% for this example), the actual time would be slightly longer.
Lithium (LiFePO4) Battery Charge Time Calculator & Formula
2: lithium battery charge time using battery charger. Formula: charge time = (battery capacity × depth of discharge) ÷ (charge current × charge efficiency) Note: Enter the battery capacity in Ah or mAh if the charger current output is mentioned in amps (A) or milliamps (mA). However, if the output value of the charger is mentioned in watts ...

How to Calculate the time of Charging and Discharging of battery?
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
