Every car is different, and there are a number of factors that can affect the amount of current drawn from the battery. However, as a general rule of thumb, most cars will have between 50-200 milliamps of the parasitic draw. Of course, this isn’t an exact science, and there are always exceptions to the rule.
Generally, a car battery pulls approximately 400 amps for small vehicles to start and more than 1000 amps for large ones. That is why the car manufacturers provide bigger amps in the car battery than it needs to start. The amps in the car battery should always remain close to 00.00 to prevent it from damaging.
This number is typically between 0.1 and 0.2 amps for most batteries. If a device draws more than this amount of current, it can damage the battery and reduce its life span. It’s important to know the maximum parasitic draw allowed for your particular battery so that you can avoid damaging it.
The exact amount of amps drawn can vary depending on factors such as the vehicle’s make, model, and electrical configuration, as well as the presence of aftermarket accessories. In most cases, the parasitic drain of a car battery while the vehicle is turned off ranges from about 20 milliamps (mA) to 50 mA.
The amps in the car battery should always remain close to 00.00 to prevent it from damaging. The reason is that even 0.5 can kill the battery in no time. Numerous factors lead to battery damage and welcome these troubles. When a car is turned off and not in use, the amperage draw of the car battery typically reduces to a very low level.
Remember a battery is a chemical device, and it is the chemical reaction within the battery that is important to know about regarding whatever circuit the battery is going to power. YES a battery could determine the amount of current flowing in the circuit.
