There are some pretty typical reasons behind why a battery fails. These are:
Age – A standard car battery typically lasts 3 to 5 years, depending on vehicle usage. After this timeframe, the risk of needing a replacement heightens.
Frequent Short Trips – Vehicles that are always taking small trips put stress on the alternator and don’t give it the time it needs to recharge properly.
Extreme Temperatures – Extreme heat or cold in the peak of winter and summer puts stress on your battery, heightening the risks of breakdown.
When it comes to dead car batteries, there are some key signs that yours needs a change. These include:
The engine is struggling to turn over
Dashboard battery warning lights are coming on
Flickering headlights
Constantly having to jump-start your car
Problems with car electrics (radio/windows/etc)
If you notice any of these signs, feel free to book in with us for a quick battery testing service, where we can identify the root cause of the issues you are facing.
