Car batteries are probably about the only part of a vehicle that we can change ourselves, with the exception of course of tyres. All that is required to change a car battery are a few short instructions and of course a new battery and fortunately most, certainly the ones on line, battery retailers will be able to provide you with both the battery and the instructions needed to change it. Although many batteries that you buy may only come with one or two years life expectancy but the better batteries will probably come with a 3 year life expectancy.
Although that is the length of time that a battery can reasonably be expected to last, your retailer will probably give you instructions on how to prolong your battery’s life, making it even more cost effective. Although giving out such information may mean that you will need a battery less often, the retailer will freely give out the information in the hope that when you do eventually need that new battery, you will return to get it from them.
The battery is an important part of the car as, as well as providing current or the lights and all the other electrical devices in the car, it also provides the current to initially start the car’s engine and then, once the engine is started, it is the engine that not only provides the power to turn the wheels but also the current to re-charge the battery via the alternator. With current passing from the engine through the alternator to the battery, the battery is able to be re-charged to ensure it can once again start the engine when needed. This means though, that as your battery, is only being re-charged when the engine is running, if you turn the engine off and leave the lights or other electrical equipment, in the car on, the battery will eventually run down and when you come to start the car, you can’t.
As a battery ages, its ability to be re-charged weakens and eventually result in no charge at all being accepted and so you have to change it. When you look for a new battery, you will probably start by looking at recommended Cheap Car Batteries and find that there are several brands of battery that are suitable for your car and so the choice of one of those is probably down to personal preference however, it is important that you choose a battery that is compatible to your make and size of car as, the battery has to not only fit in the compartment provided but, perhaps more importantly, have to have the power to start the size of engine that your car has. Although you could possibly try and remember the battery details for the next time you need to buy a new battery, most retailers will always be able to provide you with details of all batteries that are compatible to your car and engine and there may even be newer types available by then.
