Battery Capacity Calculator (Amp Hours)

Function Introduction

The battery capacity calculator is used to calculate the capacity of a battery, measured in amp hours (Ah). By inputting the battery's energy (watt-hours, Wh) and voltage (volts, V), the battery capacity can be calculated.

Calculation Formula

Battery Capacity (Ah) = Battery Energy (Wh) ÷ Battery Voltage (V)

Example

Assuming the battery energy is 100 watt-hours and the voltage is 12 volts, the battery capacity is:

100 Wh ÷ 12 V = 8.33 Ah

Importance and Application Scenarios

Battery capacity is an important indicator for evaluating battery performance, widely used in electric vehicles, energy storage systems, portable devices, and other fields.

Frequently Asked Questions

• What is amp hour? Amp hour (Ah) is the unit of battery capacity, representing the current multiplied by time that the battery can continuously provide.
• How does voltage affect capacity calculation? The higher the voltage, the smaller the capacity, and vice versa.
• How to increase battery capacity? By increasing the battery's energy or reducing the voltage.
