# How Many 12 Volt Batteries Do You Need to Run an Air Conditioner?

When it comes to running an air conditioner, many people assume that it requires a constant source of electricity. However, with the right setup, it is possible to power an air conditioner using batteries. While this may seem like a convenient solution for camping, RVing, or emergency situations, it is important to understand how many batteries are needed and how long they can last. In this article, we will explore how many 12 volt batteries are needed to run an air conditioner, as well as how long they can last in different scenarios. We will also answer some common questions related to using batteries to power air conditioners.

## How long will RV AC run on battery?

Running an RV air conditioner on battery power alone can be tricky, as it requires a significant amount of power. The length of time an RV AC unit can run on battery power depends on the capacity of the batteries, the efficiency of the AC unit, and the amount of power being consumed by other devices in the RV.

Typically, a single 12 volt battery will not be sufficient to power an RV air conditioner. You will need at least two or more 12 volt batteries connected in parallel to provide enough power to run the AC unit.

Assuming you have two 100 amp hour 12 volt batteries connected in parallel, and your RV AC unit draws 10 amps while running, you can expect to get around 10 hours of use before the batteries are depleted. However, this time can vary depending on the factors mentioned above.

## How long will a car battery run a 5000 BTU air conditioner?

A car battery can be used to power a 5000 BTU air conditioner, but it is important to note that a car battery is not designed for this purpose and may not last as long as a deep cycle battery.

Assuming the car battery has a capacity of around 60 amp hours, and the 5000 BTU air conditioner draws around 5 amps while running, you can expect to get around 12 hours of use before the battery is depleted. However, this time can vary depending on the condition of the battery and the efficiency of the AC unit.

## How long can a car battery run an air conditioner?

The length of time a car battery can run an air conditioner depends on the capacity of the battery, the efficiency of the AC unit, and the amount of power being consumed by other devices in the car.

Assuming you have a car battery with a capacity of around 60 amp hours, and the AC unit draws around 10 amps while running, you can expect to get around 6 hours of use before the battery is depleted. However, this time can vary depending on the factors mentioned above.

## Will a 2000 watt inverter run an RV air conditioner?

A 2000 watt inverter can run an RV air conditioner, but it is important to note that the size of the inverter needed depends on the size of the AC unit.

A 2000 watt inverter can run a smaller RV AC unit, such as a 5000 BTU unit, but may not be sufficient for a larger AC unit. It is recommended to consult the manufacturer’s specifications for the AC unit and inverter to ensure compatibility.

In conclusion, running an air conditioner on battery power alone can be challenging, and it is important to ensure you have the right type and number of batteries for your specific needs. It is also important to note that using a car battery for this purpose can lead to damage or reduced lifespan of the battery. Consider investing in a deep cycle battery or consulting with a professional to ensure the proper setup for your specific needs.
