This is a common question that we get asked a lot here. The answer may surprise you, but car batteries are DC (direct current) devices. However, The reason for this is that DC power is much less efficient than AC power. AC power can be easily converted to DC power. Therefore, most cars use an AC electrical system with a DC battery.
In cars, most have 12-volt lead-acid batteries. The lead-acid battery is a rechargeable battery used in cars for many years. Because this type of battery is reliable and easy to carry or cheap, due to this reason, this type of battery is used in these cars.
Why is a 12v Battery Used in Cars?
The 12-volt battery was first used in cars in the early 1900s. At that time, cars used DC (direct current) electricity, which flows in one direction only. DC electricity is produced by chemical reactions like those in a car battery.
Today’s average car on the road has a 12-volt battery under the hood. That’s because 12-volt batteries are powerful enough to start most vehicles. Moreover small and lightweight, and this battery is easily carried and installed.
But Why Exactly Are 12-volt Batteries Used in Cars? Let’s Take a Closer Look.
- 12-volt batteries are used in cars because these batteries are powerful enough to start the engine.
- The average car battery has six cells, each of which produces 2.1 volts for a total of 12.6 volts. This voltage is enough to start the cars.
- 12v batteries are less likely to catch fire if they are overheated.
- 12v batteries tend to be more durable and have a longer lifespan than other types of batteries.
- 12v batteries are responsible for starting the engine and powering the lights
What’s the Average Lifespan of a Car Battery?
The average Lifespan of a Car Battery is 5 Years. Several many things can last less than the lifespan of a car battery. For example, if you drive daily in stop-and-go traffic or bad weather conditions, your battery will likely need to be replaced or damaged. Additionally, if you don’t regularly maintain and keep your battery clean, it will wear out more quickly.
