Expert advice: How to prevent car battery trouble

Car battery trouble

Battery trouble is the number one reason that Green Flag’s technicians are called out to broken down cars. So it’s true to say that the battery is the weakest link in a car. New research by parts company Mopar shows that every year, around a fifth of car batteries in the UK need to be replaced.

The reason people get caught out by battery trouble is that frequently there are few pointers that it’s about to strike. That’s why Green Flag’s new AlertMe technology is such a breakthrough. It can tell drivers when a car battery is on the verge of failing in sufficient time for them to do something about it. If you don’t have AlertMe, here’s why your battery is the power behind your engine.

How the battery starts your engine

Up to the 1960s, pretty much every car had a hole in its front bumper where you could slot in a starting or cranking handle. By putting your back into it and turning this you turned the engine over and hopefully it fired into life. That job is now done by a starter motor which is powered by the car’s battery. Although the starter motor doesn’t operate for long, it can sap a lot of power from the battery. Turning an engine over does require a bit of oomph. Anyone who’s done the job using a cranking handle will know. And the bigger the engine and the colder the weather, which makes the oil thicker – think running in mud!– the more effort that’s required to get an engine going. Once the battery has done that main job, you might forgive it for feeling a little jaded. Continue reading

How to charge and care for a car battery

A car battery is a bit like the family pet dog. With the right care and attention, it will be faithful and obedient. But drivers who don’t give it a moment’s thought could find it lets them down and goes flat when they need it the most. And unfortunately, that’s most of us: a flat battery is one of the most common causes of car breakdowns for Green Flag members, and the most common in winter.

That goes some way to explaining why this Thursday (18 February) has been named National Battery Day. Knowing how to care for a car battery means knowing how to charge it from time to time. Researching the charging process will throw up all manner of well-meaning amateur and professional advice with conflicting guidance. So this guide is intended to help drivers understand how to better care for their car and charge its battery. Continue reading
