Car and truck batteries are vital elements of the vehicles. A battery in a car or truck is basically a storage area for energy, and the car or truck draws on this energy reserve when it is being powered on with the ignition. These batteries also provide energy for the vehicle's light mechanisms, and in traditional gasoline engines, the car battery is needed to ignite the gasoline. On the other hand, car batteries are being used in newer electric and hybrid cars to provide acceleration power. Regardless of the type of car or truck you drive, it's important to understand how your battery works and which type is appropriate for your vehicle.
One of the most common types of car and truck battery is the flooded battery, which is constructed from lead plates that sit in a reservoir of sulfuric acid. These batteries require periodic maintenance and the addition of distilled water to make up for the dissipation of hydrogen and oxygen when the battery is in use. A sealed flooded battery is a version of the traditional flooded battery that is sealed so that water isn't lost during operation.
Valve regulated lead acid batteries are a variety of sealed batteries that allow for the escape of hydrogen and oxygen via safety valves. There is also the automotive glass mat variety, which is composed of glass mats made from boron silicates. This battery has electrolytes added to it, which prevents the loss of hydrogen and oxygen. While they are preferred for certain uses, nickel-metal hydride and lithium-ion batteries are rarely used as car and truck batteries.
One of the things you need to be sure of when you are replacing a car or truck battery is that you are using the right battery for your vehicle. First, look for the group size on the battery. This number will reveal which vehicles the battery can be used in. Next, determine the make and model of your car or truck and consult an auto parts store to find out what battery choices you have.
Of course, your budget and energy needs will determine the best battery for your vehicle. Glass mat batteries, for instance, can hold charges for longer periods of time than other batteries, but they are also more expensive than the more common flooded car and truck batteries. Explore your options and talk to a professional if you are having trouble deciding on a battery.
