Battery Calculator
Calculate battery capacity, runtime, charge time, and more with our comprehensive calculator. Understand battery specifications and performance metrics for various applications.
Step 1: Battery Specifications
Understanding Battery Capacity
Battery capacity is typically measured in amp-hours (Ah) or milliamp-hours (mAh). This indicates how much current a battery can supply over time. The energy capacity in watt-hours (Wh) is calculated by multiplying the voltage by the capacity.
Step 2: Usage Parameters
About Battery Efficiency
Battery efficiency refers to how much of the stored energy can be effectively used. This is affected by factors like temperature, age, and discharge rate. Higher efficiency means more of the battery’s capacity is available for use.

Battery Calculation Formulas
Runtime (hours) = Battery Capacity (Ah) / Load Current (A)
To calculate how long a battery will last, divide the battery capacity by the current draw. For example: 100Ah battery with 5A load = 100 / 5 = 20 hours.
Energy (Wh) = Capacity (Ah) × Voltage (V)
To calculate the total energy stored in a battery, multiply the capacity by the voltage. For example: 100Ah × 12V = 1200Wh.
