There are five different types of car batteries:

Ignition batteries are used to start the engine of a car. They’re also used to start a generator or other devices that require a lot of electricity. They are also used to start other types of vehicles, such as tractors, trucks, and boats.

Deep Cycle Battery

A deep cycle battery is a battery that is used to start a car. It’s also used to start a generator or other devices that require a lot of electricity. Deep cycle batteries are used in electric vehicles, hybrid vehicles, and some battery-powered tools. This type of battery provides more consistent power to your vehicle over a longer period of time.

A wet cell battery is a battery that requires the addition of water to the cells to keep the battery working. It’s used to start a car and other devices that require a lot of electricity. Such a battery is less expensive, but it has a limited lifespan.
