Next, we need to consider the capacity of a car battery. A typical car battery has a capacity of around 50-60 amp hours (Ah), meaning it can deliver a current of 1 amp for 50-60 hours before being fully discharged. To calculate how many batteries are needed to support a 1000W appliance, we need to divide the required current (83.33A) by the battery capacity (let’s use 50Ah for this example).

83.33A ÷ 50Ah = 1.67 batteries. Obviously, we can’t use a fraction of a battery, so we would need to round up to 2 batteries. Therefore, to power a 1000W appliance for an extended period, we would need two car batteries that are connected in parallel to deliver a constant current of around 83.33 amps.

It’s important to note that this is a simplified calculation and other factors such as battery age and condition, temperature, and the type of battery can affect how long the batteries will last. Additionally, it’s always a good idea to consult with a professional or refer to the manufacturer’s recommendations before attempting to power a high wattage appliance with car batteries.
