Your vehicle has a lot of different systems working together as one to ensure you that you can use your car and all of its features when required. When it comes to the electrical system, there are actually two main components that are responsible for its proper functioning. One is the alternator, and the other one is the car battery. The battery is really the one storing the electrical charge that is required for all the electrical systems in your car to work, from head and tail lamps to hazard lights and even things such as the windscreen wipers, heaters and a whole lot of other things.
Modern vehicles all come equipped with a battery when first bought. Essentially, they cannot run without a battery or a malfunctioning one. The main reason for this is that cars now use battery power in order to start the engine: if the battery is dead or malfunctioning, you cant even start up your car, let alone drive it somewhere else. Therefore, checking on your vehicles battery is perhaps one of the most important things you should do when it comes to vehicle maintenance, along with checking fluid levels or noticing any strange noises.

First of all, lets understand how a car battery works. Since all of your vehicles electrical system run off the battery, the latter should have a method to charge itself. This is accomplished in two ways: either by the alternator or by providing an external charge (such as during trickle charging). You need to ensure your car always has enough charge available for it to start, hence the reason why people recommend to start your car daily when not in use for a long time. The charge may also not transfer properly between terminals due to worn cables or oxidation damage, in which case you can replace them with a twin automotive cable or another suitable wiring.Batteries in vehicles have a certain lifespan, after which they will need to be replaced.

Typically, the lifespan of a battery can vary between two to five years, with the average battery lasting something in the region of three years, give or take a few months. Sometimes, your battery can give you trouble before that due to other reasons, such oxidation damage. If possible, try to fix such issues first before replacing the battery itself: chances are that you will just need some tesa tape Australia to fix the issue yourself and make the battery good for another six months or so.

The last thing you need to keep in mind is that you shouldnt attempt battery repairs yourself if you dont have any knowledge about them. You risk injuring yourself, ruining your battery and even other vehicle components if you arent careful. It is best that you take your vehicle to a mechanic for an inspection if that is the case.
