The formula for the Battery Discharge Time Calculator is: Discharge Time (in hours) = Battery Capacity (Ah) / Load Current (A). This formula provides an estimate of how many hours the battery can support the given load. How to Use: Utilizing the Battery Discharge Time Calculator is simple and involves the following steps:
You also need to know the capacity of the battery, in unit mAh. Now just divide the battery capacity by the current to get the battery time. Example: 1000 mAh battery and 100 mA load gives 1000 / 100 = 10 hours of battery time.
Discharge Rate: This is how fast the battery loses its charge. It can be changed by things like how you use your device, the temperature, and the battery's age. Put these numbers into the formula to find out the battery run time or battery discharge time for your device.
As the discharge rate ( Load) increases the battery capacity decereases. This is to say if you dischage in low current the battery will give you more capacity or longer discharge . For charging calculate the Ah discharged plus 20% of the Ah discharged if its a gel battery. The result is the total Ah you will feed in to fully recharge.
Formula: C-rate in time (minutes) = (1 ÷ C-rate) × 60 The chemistry of battery will determine the battery charge and discharge rate. For example, normally lead-acid batteries are designed to be charged and discharged in 20 hours. On the other hand, lithium-ion batteries can be charged or discharged in 2 hours.
To calculate the hours, you need to know the load’s current draw. Divide the battery’s capacity (5000mAh) by the load’s current draw (in milliamps) to get the runtime in hours. How long will a 300Ah battery last?

Battery discharge time is fairly easy to calculate in principle, assuming the load draws constant current. This means the load will always draw the same amount of current as long as the battery voltage is within the range allowed by the load specifications. "Load" is a general term for eveything powered by the battery.

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.
