5 Warning Signs You Need a New Car Battery
Car batteries face many different demands, and there can be over 200 electronic control units that require power, even when the car is parked. Recognizing how to maintain a car battery is very important for avoiding unexpected breakdowns and costly repairs, especially as battery failures remain the leading cause of vehicle breakdowns in the UK.
When Should You Replace A Car Battery?
One obvious car battery replacement sign is when your vehicle doesn't start particularly well. If you turn the key or press the start button and hear spluttering sounds, it is likely that there could be something wrong with your battery. If the electrical systems in your car begin to falter, this can also be a car battery replacement sign. Slow-responding electric windows or a sluggish heating system can indicate your battery is struggling to maintain sufficient power levels. These problems usually become worse during colder months when the car needs more electrical power.
Another car battery replacement sign is when the dashboard battery warning light comes on. This can signal problems with your electrical system, alternator or battery, which could lead to complete battery failure if not addressed promptly. It is equally important to keep your tyres checked regularly and at Protyre, we offer free tyre checks alongside our wide range of tyres from brands like Pirelli and Sumitomo.
Many modern vehicles are equipped with start-stop technology and they actively monitor battery performance. When the system detects insufficient power, it may disable the start-stop function to preserve energy for essential operations. This intelligent feature often serves as an early warning system for battery problems. Car batteries usually last between five to seven years. If your battery is within this age range and it starts showing signs of failing, it may need replacing. You can see how old your battery is by checking the manufacture date on the casing.
How to Maintain a Car Battery
Regular maintenance can significantly extend the life of your battery. Keeping the terminals clean, making sure that the connections are secure and using a smart charger if your car is inactive for a long time are all great car battery care tips.
