They measure this in amp hour ( Ah), milliamp ( mA), and by milliamp hour ( mAh).Īmp hour indicates the capacity of the battery to store energy. Using an amp meter, you can also measure the number of amps in a car battery. How does amp meter work?Īn amp meter can measure electrical current in two ways: By measuring the flow of electrical current, which can be considered as a “draw” of energy in an electrical circuit and by the amount of energy in a battery, which can be thought of as the “continuity” of an electrical current.Īs I’ve established, an amp meter (also called an ammeter) measures amps flowing in an electrical circuit or conductor’s electrical current. The higher the pressure generated by an electrical current’s power source, the higher the number of volts forcing the electrical current through that circuit. Voltage is the force of electric current that is pushed through an electrical circuit. While amps are the amount of electricity in a circuit, volts measure the force of that electric current. As I’ve mentioned above, a regular family hatchback’s battery has a 48-amp capacity. In terms of a vehicle battery, an amp indicates how much electricity can flow through the battery to start and run the car.

Amp (or ampere) is a unit that measures the rate of current in an electrical circuit or conductor. Now that you have an idea of what amps are, I’ll deep-dive into explaining this technology. It is because the battery plates can buckle due to fast charging, and in some instances, may even explode. However, fast charging isn’t always the best solution for vehicle batteries. The higher the charge rate’s output, the faster the battery will take to recharge. They also have different charging rates ranging from 2 amps to 12 amps (sometimes even far higher). There are many different chargers on the market, from analog, digital to different brands and designs. They usually recharge batteries at around 2 amps and need around 24 hours to charge a hatchback car’s battery fully. These battery chargers use mains current to recharge vehicles’ batteries. The best automotive battery chargers feature built-in amp meters. What is an amp meter? First you need to know what is ampere
