* Voltage: The voltage of a car battery is usually 12 volts. This means that the battery can provide a potential difference of 12 volts between its positive and negative terminals.
* Amp-hours: The amp-hours of a car battery indicate how much current it can deliver for a given period of time. For example, a battery with a capacity of 50 Ah can deliver 50 amps of current for one hour, or 25 amps of current for two hours, and so on.
The size and capacity of a car battery depend on the vehicle's electrical system and the accessories that are installed. Smaller cars with basic electrical systems may have batteries with capacities around 40 Ah, while larger cars with more powerful electrical systems and features like heated seats and power windows may have batteries with capacities up to 100 Ah or more.
It's important to note that the strength of a car battery is just one factor that affects the vehicle's electrical system. Other factors include the alternator, starter motor, and electrical wiring. If any of these components are faulty, it can affect the battery's ability to provide power to the vehicle's electrical system.
