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.

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
