The electrical system of a vehicle is often neglected until it fails, but with some maintenance here and there you can save yourself money and time in the long run! Battery failure is one of the most annoying problems that can be easily avoided if you test them regularly and replace them when necessary. In this article, we will talk about how long do car batteries last and how to avoid battery early failure, and what causes car battery failure.
How long does a car battery last?
On average, car batteries last between three and five years. Your battery's capacity will slowly reduce over time. You should test your car battery after 3 years of use and it may still be safe to use for a little bit longer. Getting your battery tested often will lower the chance of you getting stranded due to a dead battery.Car battery maintenance
Be sure to test your battery voltage regularly. The quickest way to test your battery’s voltage is by using a voltmeter. Purchasing your own digital voltmeters is the easiest to use. The voltage test should be done at least 12 hours after your car has been turned off to get the most accurate reading. Normally, A fully charged battery will typically display a reading between 12.4 and 12.8 volts. if your car battery voltage is anything outside that range, you should take it to a mechanic for vehicle inspection from a mechanic. Dedicated battery testers indicating health/state of charge and condition, are even better, and this is what your workshop will/should be using at each service – if not, ask them.
Secondly, Leaving your car unused for long periods of time will likely cause a problem with the battery not having enough time to recharge. Your car will be in optimal condition when it's used regularly, It's always good to take your car for a drive once every week if possible. This is because of the fact that it will help warm up your engine and circulate your fluids. If you won't be using your car for a few weeks, it's likely that the battery will need attention when you use it again. In many cases though, starting a car and then simply driving around the block or a few km, does nothing too little to improve the SOC (state of charge), and in some cases could be detrimental.
Thirdly, make sure to clean your battery regularly. A car battery with grime, dirt, or dampness will have a leakage across the casing to cause a short circuit. This is why you should keep your battery clean and dry! Doing this at least once a month will reduce buildup. The corrosion that accumulates on battery terminals and lead clamps is very common. Lead clamps and terminals can be corroded, which impedes the flow of electricity through the battery. Making sure to clear this grime or build-up is important in order to ensure that your battery lasts a long time and works efficiently.
Lastly, Powering up electronic accessories while the engine is off will discharge a battery more quickly. This is because when the engine switches off, your car's alternator automatically shuts down and electronic accessories instead drain power from your car’s battery. One way to avoid this is to get into the habit of checking that everything is switched off every time you exit your car.
Signs that your car battery needs to be replaced?
If you are noticing a few signs that your battery might need to be replaced, it is best to take preventative measures. If you are finding your car reluctant to start, it could be a sign that the battery needs replacement. Additionally, If you notice your headlights seem dimmer than usual, it's time to get the battery checked as It can be an early sign of weakness in the battery.Contact a professional
