Battery discharge time is the duration a fully charged battery can power a device before needing a recharge. Factors like battery capacity, power consumption, and usage patterns affect discharge time. Knowing how to calculate and optimize battery discharge time is key to getting the most from your devices.
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.
This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C. 0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity.
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:
The charging/discharge rate may be specified directly by giving the current - for example, a battery may be charged/discharged at 10 A. However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery.
My battery capacity will be about 80-90 Ah and I plan to use discharge 20-30 Ah per cycle. I''d ideally like 1 battery recharged (30 Ah) in 2 hours max. ... If I can safely …

As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA.
