Battery Parts and Types

Battery Parts

A car battery is made up of several components. The main parts include the lead plates, the electrolyte, and the case. The lead plates are the battery’s source of power. They are made of lead and lead oxide, which reacts with the electrolyte to produce an electrical current. The electrolyte is a mixture of sulfuric acid and water that provides a medium for the chemical reaction to take place. The case is typically made of a durable plastic material that protects the internal components and prevents leaks.

Battery Types

There are several types of car batteries available. Lead-acid batteries are the most common and are widely used in most types of vehicles. They are affordable and have a good balance of power and longevity. There are also gel batteries, which use a gel electrolyte instead of a liquid. These batteries are more expensive but offer better performance in extreme temperatures. Lithium-ion batteries are becoming more popular, particularly in hybrid and electric vehicles. They are lightweight and offer high power output but are also more expensive and require specialized charging equipment. Finally, there are absorbent glass mat (AGM) batteries, which have a glass mat separator that absorbs the electrolyte. These batteries offer excellent performance in demanding conditions but are also more expensive.
