What is a battery capacity?
Battery capacity refers to the amount of energy that a battery can store, and is measured in Watt-hours (Wh). In other words, it's the amount of energy that the battery can supply over a certain period of time.
To calculate the amount of time a battery will last, you need to know both the battery's capacity and the power consumption of the equipment it's powering. Power consumption is measured in Watts (W), and represents the rate at which energy is being used by the equipment.
Using the formula Time = Energy / Power, you can estimate how long a battery will last based on its capacity and the power consumption of the device. For example, if you have a 160Wh battery and you're using it to power a 60W RED camera, the expected battery life would be:
Time = Energy / Power Time = 160Wh / 60W Time = 2.67 hours
This means that the battery will last approximately 2 hours and 40 minutes when powering the RED camera. It's worth noting that this is just an estimate, as the actual battery life can be affected by a number of factors such as temperature, age, and usage patterns.
Understanding battery capacity is important when selecting a battery for a particular application, as it ensures that the battery will be able to provide sufficient power for the intended duration. It's also useful for managing power consumption and planning for extended use of equipment in remote or off-grid locations.
