As we already mentioned, a car battery is one of the essential components of any car and a crucial part which not only provides electrical power for the engine but for all other car systems. That is why a failing car battery is a serious problem and can leave you stranded by the side of the road or not being able to start your car. But, let‘s see what other problems could be the result of a car battery on its last legs.
1. Flickering headlights
This is one of the first signs of a failing battery or problematic alternator. If you notice flickering headlights or low-intensity light, you can be sure that the battery is getting empty and cannot power the lights properly. In real life, headlights will flicker once or twice but then function as they should for some time. Only after that, you will notice that the light is dimmer. Then you will know that very soon, the car will stop.
2. Some systems may not work
Since modern cars are full of electrical systems, not just for infotainment but for comfort or safety, a failing car battery can affect some of them. Simply, if your car has a weak battery, turning on the music, phone charger, climate control, headlights and big screen on the dashboard will put even more stress on it. That is why a car‘s electronic system is designed to shut off some of the components in order to keep the battery powerful enough to power the car‘s engine. If you see that the battery is near its end, shut down everything except the headlights and drive straight home.
The biggest problem with a battery dying in the middle of a drive is the fact it will leave you stranded. Simply, a car‘s electrical system cannot rely only on the alternator (especially if it isn’t in good condition) to provide all the power for lights and spark plugs, and if the battery is dead, it will stop producing power and eventually the engine will start to misfire and then shut down. These are especially big problems since you are unable to start the car even with the jump starter kit or by pushing. Since the battery is dead, there is no point of jumpstarting the car. Even if you succeed, the car will stall after a few miles. The only solution is to replace the battery or to tow the car home.
4. Failure to start
The biggest and most common way of bad car battery affecting your car is a failure to start. In most cases, a car will have a hard time starting and you could experience cranking with no start, but in some cases, the car would be completely dead. This happens when the battery is totally empty and cannot power any car‘s systems or starter motor. In that case, you should replace it and check the rest of the electrical system for potential damage, naked wires and inspect the reason for battery drainage. There can be numerous things that could go wrong and you want to be sure that this doesn‘t happen again.
