| Know All About A Car Battery |

A car battery provides a physical reserve of energy to the car. It is used to power up a car during ignition and provide energy for the lighting systems. It can also be used to provide traction energy for the electric cars.
A car battery is typically made up of lead oxide electrode plates immersed in a mixture of sulfuric acid and water. When the battery is in use, the sulfuric acid reacts with the lead oxide plates to produce electrical signals. The car battery is charged by a device known as alternator, which converts the mechanical energy from the engine into electrical energy. This energy is then used to prompt reactions within the battery. In this way, the car battery is able to store energy chemically. There are various types of car batteries available in the market. The most common ones are described below. Flooded type: The most common car battery is the flooded type. This battery is a collection of lead plates submerged in sulfuric acid in an open reservoir. This battery requires regular replenishment of water to balance the loss of lost as hydrogen and oxygen gases during the electrolysis process. Sealed type: A sealed car battery is essentially a flooded car battery which is sealed to prevent the loss of water. This type of car battery requires little or no replenishment of water. VRLA type: A VRLA (Valve Regulated Lead Acid) battery has an additional catalyst surface on which the hydrogen and oxygen gases released during charging unite to form water. In this way, this type of car battery does not require water replenishment. Glass Mat type: This type of car battery comprises of boron silicate glass mats that are soaked with the electrolyte present between the plates. This battery does not lose hydrogen or oxygen. It also stores charge for long periods, discharging only 1to 3 percent monthly. However, the price of this type of battery is usually two to three times more than other batteries. Silica Gel type: This type of car battery has slow recharge rates and is used only in cars that are driven occasionally. NiMH type: A NiMH (Nickel Metal Hydride) car battery packs high energy density in each unit of space. This battery can be recycled easily, as it does not contain any toxic metals. Li-ion type: A Li-ion (Lithium-ion) type of car battery also has high energy density. It discharges very less over a long period of time. With the wide range of car batteries available, you can easily choose one that is most suitable for your car and your personal considerations. Related Articles
