Battery Capacity Formula. The formula for calculating battery storage capacity is given below: Battery Capacity = Current (in Amperes) × Time (in hours) Where, Battery Capacity represents the total amount of electrical energy a battery can store, typically measured in ampere-hours (Ah) or watt-hours (Wh).
The basic formula for calculating the capacity of a battery is to multiply the voltage by the current and then by the time. The formula is as follows: Where: Capacity is the battery’s capacity in ampere-hours (Ah). Voltage is the battery’s voltage in volts (V). Current is the battery’s current in amperes (A).
To find the current capacity of a battery in use, you can use a multimeter to measure the current drawn by the load. Alternatively, you can use a battery monitor that displays the current capacity of the battery in real-time. In what way can you calculate the run time of a 12V battery?
Capacity is the battery’s capacity in ampere-hours (Ah). Voltage is the battery’s voltage in volts (V). Current is the battery’s current in amperes (A). Time is the time the battery can last in hours (h). For example, if you have a 12V battery that can deliver 5A for 20 hours, the capacity of the battery would be:
The capacity of a battery is the amount of energy that it can store. A battery's capacity is expressed in amp hours (Ah), which is a measure of electrical current over time. One amp hour equals one amp of current flowing for one hour. The higher the Ah, the longer the battery will last.
The discharge current represents the rate at which the battery is discharged. To calculate it, use the formula: Discharge Current (I) = Rated Capacity (C) / Discharge Time (t) For example, if a battery has a rated capacity of 100 Ah and will be discharged over 10 hours, the discharge current would be: I = 100 Ah / 10 hours = 10 A
To calculate the total capacity of batteries in a series-parallel configuration, you need to first calculate the capacity of each parallel group, and then add up the capacities of each group. When estimating the battery life of a device, it is important to consider the dis charge current and charge current of the battery.

For a given capacity, C-rate is a measure that indicate at what current a battery is charged and discharged to reach its defined capacity. A 1C (or C/1) charge loads a battery that is rated at, say, 1000 Ah at 1000 A during one hour, so at the end of the hour the battery reach a capacity of 1000 Ah; a 1C (or C/1) discharge drains the battery at that same rate.
