Top 10 Car Battery Facts
A car battery gives the initial boost that cranks and starts the engine of your vehicle. Once the engine is running, the battery could, theoretically be removed and the car would run quite happily. However, we wouldn’t recommend testing this theory as you’d have a problem restarting the engine once the ignition was switched off.
There are many misconceptions and myths surrounding car batteries, so below we have set out ten facts about the battery under your bonnet, facts that may provide you with a better understanding of how it works and how to get the best out of your battery.
Vehicles need to be driven regularly and for distances that allow the battery to recharge itself properly or it will discharge its power and run flat. In fact, regular longer runs could double the life of your battery
Don’t be fooled, or rush out to buy a new battery if the battery warning lights up on your dashboard; it doesn’t always mean that there is a fault with the battery. It could be a problem with the vehicle’s charging system, or some other electrical fault. But we do recommend that you check with your nearest garage or contact us as soon as possible because to delay could result in serious damage to the electrical system and may indicate an imminent breakdown
If the car battery leads are connected incorrectly it can cause the electrical current to flow in reverse polarity resulting in serious damage to the vehicle’s electronic system. Consequently the fuses could be destroyed and potentially cause the battery to explode.
For this reason many motorists have their batteries fitted by a professional and why we encourage motorists to have their batteries fitted by us.
A faulty or failing battery can affect the fuel economy as the vehicle’s alternator will have to draw more horsepower to charge the battery adequately, meaning the added load puts more pressure onto the battery and uses more fuel.
Extremely cold weather can result in the battery losing power. For this reason, today’s batteries include cold cranking amps (CCA) that give that extra boost to assist starting on cold winter mornings. CCA is the number of amps delivered by the car battery at 0℉ within 30 seconds without dropping below 7.2 volts. The higher the CCA of a particular battery the better will be the performance. But be aware, hot outside temperatures can also deaden your battery – for more on this click here to view our article titled ‘Has my car battery died’.
All dead car batteries should be recycled as they contain lead dioxide and sulphuric acid which can harm the environment, as well as being dangerous to your health.
If you have replaced the battery yourself you should take the old one to your local recycling centre or scrap metal facility, however as part of our fitting service, we can do this for you, completely free!
Car battery size and choosing the correct battery for your make and model of vehicle is important – pick the wrong one, then no matter your cars specification, or how well it is maintained, it simply will not perform as it should or could.
