What is a car battery?

A car battery is what provides your car with the electrical energy to run, and for the accessories to operate.

Here, you can discover the purpose, functionality, and types of battery available to help you make informed decisions on your battery-related needs.

Wikipedia provides a good high-level overview of what a car battery is, describing it as “a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle” (https://en.wikipedia.org/wiki/Automotive_battery).

A car battery is also responsible for powering the car’s electrical load. Vehicles are not the same as they were 20 years ago – back then, the battery was only needed to start the car. Now – vehicles require the battery to power sensors, displays, safety features, entertainment systems and more.

What is a battery made of?

A battery comprises several different materials and solutions to ensure that it charges, discharges, and operates effectively. In short, there are eight components that make up a battery – anodes & cathodes, plates, electrolyte, container, plate separators, lead terminals, inter cell connectors, and vent & vent caps. Take a look at the specific materials used to make a standard battery.

How does a battery power a car?

The primary purpose of a car battery is to start the vehicle. It does this by providing electricity to the car’s starter motor that, in turn, rotates the car’s flywheel and gets the engine going. The alternator, which is connected to the car’s engine, then generates electricity to recharge the battery and keep the car moving, as well as managing the car’s load – that is, keeping our added little luxuries working such as heated seats, power windows, and Wi-Fi connection.

What are the functions of an automotive battery?

The functions of an automotive battery are simple: starting, running, and powering the electrical load – i.e., the electrical accessories – in your vehicle. Such batteries provide the electrical power, chemical energy conversion to electrical energy, and voltage stabilisation required to make this functionality possible. They also deliver extra power to keep the car running when the vehicle’s electrical load exceeds the supply from the charging system.

You can watch more on the functions of an automotive battery in this YouTube video by The Engineering Mindset.

What are the different types of battery?

There are many different types of battery, varying in size, power, and performance. Battery types range from your standard AA alkaline battery, used frequently in the home, through to lead-acid batteries that can be used for sizable industrial machinery. Lead-acid batteries are also the type of battery used in an automobile.

What are the different types of lead-acid battery?

There are many different types of lead-acid battery whereby each provides either starting or deep cycle power. The type of battery required is generally selected according to how much power can be delivered, and for how long that power needs to be delivered.

Important to understand is that starting batteries are used to power engines on vehicles, and deep cycle batteries are used to power electrical accessories, such as lights, which require a steady level of power for a long period of time.

Deep cycle batteries can come in various types for both consumer and industrial purposes – everything from 6-volt batteries for flashlights through to industrial-power batteries for safety alarms, medical equipment, oil drilling, and much more.

In an industrial deep cycle battery, the plates are much thicker, and therefore it can last for many years. We offer a good range of lead-acid car batteries, available in our online shop
