Types of car batteries
There are many different types of car batteries. An automotive battery is used to start the car, power the lights, and more. As you drive, your engine consistently recharges the battery. However, these batteries have a shelf life and at some point, you will need a replacement battery. There are many batteries on the market to choose from, and you need to determine which is best suited for your car and circumstances.
The wet/flooded battery is popular because of its low price. The battery design utilizes plates that are freely suspended. The plates are insulated from each other as the negative plate is completely sealed in a separator bag. These are maintenance free and sealed so no gases are replaced. The fluid in the battery will last until the battery dies so no need to keep topping it up.
This type has a calcium alloy that is on different charged plates. The calcium reduces the amount of fluid loss and the rate of self-discharge is much slower. One disadvantage is that you can seriously damage the battery if you overcharge it. The bubbles that move through the fluid are important, as they are responsible for mixing the different acid densities.
Lithium ion battery
Some high-performance vehicles or limited edition cars will offer lithium ion battery. This battery is primarily used for electric vehicles, as they are lighter in weight which provides a more fuel-efficient vehicle. These are very expensive batteries.
A deep cycle battery will supply power for a longer period. These are typically used on small boats, golf carts, or electric vehicles. You will also find these used to collect and store solar and wind power. These batteries have thicker plates inside the battery as this increases the capacity charge. They are seldom used for cars because they have a high discharge rate, so the battery will lose power very quickly.
