Car batteries are essential components of cars, providing the power they need to start and run properly. There are three main varieties of car batteries: lead-acid, absorbed glass mat, and lithium-ion. Each type has its own advantages and disadvantages, so it’s important to know which battery is best suited for your vehicle.
Lead-acid batteries are the oldest and most commonly used battery in cars today. They consist of cells connected together that contain lead plates in an electrolyte solution. Lead-acid batteries are inexpensive, but they do not last as long as other types because they need to be replaced often due to sulfation. They also do not withstand extreme temperatures very well.
Absorbed Glass Mat (AGM) Batteries
Absorbed glass mat (AGM) batteries are more expensive than lead-acid, but they last longer and can handle extreme temperatures better. AGM batteries have many of the same components as lead-acid batteries, but the plates are suspended in a porous glass mat, which absorbs the electrolyte solution making them spill-proof and safer.
Lithium-ion batteries are becoming increasingly popular for cars due to their long life and lighter weight. They do not contain lead plates or dangerous acids, so they provide more energy in a smaller package. They also have no memory effect and do not require regular maintenance.
What is the most common car battery?
The most common car battery is the lead-acid battery. It is inexpensive and widely available, but it does not last as long as other types of batteries. AGM batteries are becoming more popular due to their spill-proof design and better performance in extreme temperatures, while lithium-ion batteries offer a longer life span and lighter weight but are more expensive.

How often should car batteries be replaced?
Car batteries should be replaced every three to five years. It is important to check the battery regularly for signs of corrosion or wear, as this can lead to reduced performance and early battery failure. Additionally, if the car is not used frequently, the battery may need to be replaced sooner due to sulfation caused by lack of use.
How do I know what battery to buy for my car?
Check for the group size on your old battery. This number indicates the size and capacity of the battery.
Check to see if your car manufacturer recommends any specific brands or types of batteries.
Choose a battery with a higher cold cranking amp (CCA) rating than your old one, as this will provide more power for starting in colder weather.
Compare prices and reviews to find the best value for your money.
Car batteries come in three main varieties: lead-acid, AGM, and lithium-ion. Each type has its own advantages and disadvantages, so it is important to research the best option for your vehicle and budget. Additionally, car batteries should be checked regularly for signs of wear and replaced every three to five years. With the right information, you can find the perfect battery for your car.
