$begingroup$ You''re right that the currents won''t be identical, but they will be quite similar; in particular with lithium cells the voltage drops significantly as the cells discharge, so a cell with a higher voltage will tend to
Ohm''s Law states that current (I) in amperes is equal to voltage (V) divided by resistance (R). To calculate the amperes, divide the ampere rating (Ah) of the battery by its
Step 2: Convert Battery Capacity to Watt Hours (Wh) If the manufacturer provides the battery capacity in amp-hours (Ah), convert it to watt-hours (Wh) if necessary. To do this, multiply the amp-hour rating by the battery''s voltage. The formula is as follows: Watt hours (Wh) = Amp-hours (Ah) * Voltage (V) Step 3: Determine Device Power Consumption
The average current is the total current consumption divided by the measured duration. As per the above image, there are two average currents. Case 1: 866.82 uA over 2 mins of windows (complete cycle).. Case 2: 682.63
Just integrate the current as a function of time, and express the result in ampere-hours. If the current is constant you can just multiply the current by the length of time, in hours, that the battery supplied this current.
At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero; As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge decreases is proportional to the amount of current, p.d or charge it has left

How Do You Calculate Battery Runtime Using Capacity and Current Draw? Battery runtime can be calculated using the formula: Runtime (hours) = Battery Capacity (Ah) / Load Current (A). This formula provides a
The Nominal Capacity of the battery is given at this C-rate. The discharge current can then be worked out from the C-rate and the Nominal Capacity. For example if a battery has a C1 capacity of 400Ah, this means that when the battery is discharged in 1 hour, it has a capacity of 400Ah.
The discharge current can then be worked out from the C-rate and the Nominal Capacity. For example if a battery has a C1 capacity of 400Ah, this means that when the battery is discharged in 1 hour, it has a capacity of 400Ah. The discharge current would have to be 400A to discharge the battery in an hour.
Round the breakers up to next common size and you have600A vs 500A. If the battery cabinet design is only for capacity (meaning all cabinets must be on line to handle discharge) one could use 500A breaker, maybe even 450A in the scenario above. Sometimes it is requested that 600A be used however.
Electricity usage is billed in kWh. 1 kWh is the the electricity consumed by running a continuous load of 1000W for one hour. The output of a solar system is also measured in kWh. It is therefore helpful to know the capacity of a battery in kWh. This is worked out as follows: Capacity in kWh = (Capacity in Ah x Operating Voltage (V)) / 1,000
To calculate the maximum current draw, you divide the battery's amp hours by the desired runtime in hours. So, if you want the battery to last for 5 hours, the device should draw around 20 amps on average. Alternatively, you can convert amp hours to amps to estimate how much current you need to charge a battery at your desired rate.
The higher the discharge current, the more power the battery can provide. For example, a battery with a maximum discharge current of 10 amps can provide twice as much power as a battery with a maximum discharge current of 5 amps. This number is important for two reasons.
