Here's how it works:
* Chemical Reaction: A car battery uses a chemical reaction between lead plates and an electrolyte (usually sulfuric acid) to store energy.
* Voltage: The chemical reaction creates a potential difference, or voltage, between the battery's terminals (positive and negative).
* Current (Amps): When a circuit is connected between the battery terminals, electrons flow from the negative terminal to the positive terminal. This flow of electrons is called current, measured in amps.
Think of it like this:
* Voltage: The pressure that pushes the electrons through the circuit.
* Amps: The amount of electrons flowing per second.
So, the battery doesn't *make* amps. Instead, it stores energy and provides the voltage that allows current (measured in amps) to flow when a circuit is connected.
Here's how car battery capacity is described:
* Amp-hours (Ah): This measures the total amount of energy the battery can store. A higher Ah rating means the battery can supply a given current for a longer time.
* Cold Cranking Amps (CCA): This measures the battery's ability to provide a high current for a short time, specifically for starting the car in cold weather.
