The very first cars that were ever made had electrical lines that serviced the essential engine function of firing spark plugs to a timer. These cars with Canada brakes had no other use for electrical power in the car and the system was run off the car’s electrical generator. Every modern vehicle that runs on the internal combustion principle runs an entire subsidiary electrical power system that is powered by a storage lead-acid battery. There are many electrical systems designed into the modern auto that run off this storage battery: the vehicle’s starter motor, the engine management systems, the vehicle’s safety and security functions and the convenience features designed into the passenger cabin.
The typical car battery is a rechargeable lead-acid design. A chemical reaction inside the battery allows it to supply power, and also allows it to restore its electrical potential, with help from power from the engine’s alternator. Also to have the Canada brakes with power is an important part of maintaining a car. There are many events in the car’s life that can shorten the service life of its battery. The heat of the engine, too high or too low a level of electrolyte in the battery, excessive jolts or shocks delivered to the battery, can all considerably lower the life of a battery. With even the best care taken, the lead-acid battery lasts no longer 3 to 4 years before it comes up due for replacement. One begins to suspect an imminent need for its replacement when the headlamps of the car regularly dim when running off the battery without help from the engine. To begin with, you could suspect a freak low-charge situation, and charge the battery by using connecting cables and connecting it to the battery of another vehicle that happens to be fully charged. If such a boost helps it charge up properly, you could try to run the car for a few days, to see if the car’s charging system is able to keep the battery topped-up with charge. If the battery level keeps dropping down, it could mean that the alternator needs maintenance; but for the most part it is usually that the battery is due for replacement.
To replace a car battery is one of the easiest car maintenance jobs of them all for the do-it-yourself. If your battery acts up even when it is new, you could take it in for replacement under warranty. If it has lived out its proper service life though, you need to start shopping around for a good deal on a new battery. There isn’t much point choosing the discount battery, as a name-brand battery is not often much more expensive, and it comes with a reliable warranty. The first step to replacing a battery is to unfasten it from its seating inside the hood. Each model of car has its own unique battery- fastening system; some of them use a strap to hold the battery in place, others use screws and clips. To begin the process, turn off the engine, and open and securely prop up the hood of the car. Whatever you do with a car’s battery you need to make sure that you never ever short the battery’s terminals out with any metal object. Doing so can cause an explosion. But since a car battery operates on a 12 volt DC system, you need not worry about shocking yourself.
Look closely at the mechanism used to secure the battery in place. Undo the fastening, and safely stow it away for use with the new battery. Next, it is time to disconnect the battery’s electrical connections. All modern cars use what is known as a negative grounding system to connect the battery to the ground, or the body of the car. Disconnect the negative cable first, and then the positive. Call up some help if you need, to hoist the battery out of its seating, as it can be quite heavy. You will now need to look closely at the battery type and specifications to get a new one that will match the electrical and physical properties of this one. Batteries contain chemically toxic chemicals and components and need to be disposed off responsibly. Most battery dealers have arrangements with state-sponsored battery recycling programs and will take back your old battery.
Once you have your new battery, all you need to do is to go backwards with the steps you used to disconnect the battery. When you make the electrical connections again, make sure that you connect positive to positive and negative to negative; making wrong connections can result in an explosion. Check the battery terminals for any corrosion and replace them if they appear to be too worn. If they are the screw -type, tighten them back onto the battery very securely; a loose battery connection can result in unreliable operation. This really is all it takes to replace the battery of a car.
