How do I calculate the battery capacity I need for my application?

Calculating the required battery capacity involves considering several factors, including the expected discharge period, the maximum current draw, and the desired depth of discharge (DOD). A good starting point is to determine the total energy requirements of the application in watt-hours (Wh). This can be calculated by multiplying the power consumption in watts by the duration of use in hours. Then, the desired battery capacity in AH can be estimated by dividing the total energy requirements by the battery voltage and considering the DOD.

For example, if an application requires 200 Wh of energy and the desired DOD is 50%, a 12-volt battery with a capacity of at least 20 AH would be required. However, this calculation assumes a 50% DOD, which may not be suitable for all applications. Additionally, factors like efficiency losses, temperature, and aging should also be taken into account when determining the required battery capacity. By carefully considering these factors and performing the necessary calculations, users can select a battery with the right capacity to meet their specific needs and ensure reliable performance.
