Car Starts After Disconnecting And Reconnecting Battery

It is now uncommon to have batteries problem in cars and most time reconnecting batteries solves the problem. Didn’t it happen to you? 

It’s happened to all of us before and you have here because you may face it. You go to start your car and it doesn’t turn over. You check the battery and it appears to be dead. So, you disconnect and reconnect the battery, and surprise! The car starts right up.

But what exactly happens when you do this? Why does disconnecting and reconnecting the battery work to start a car?

What causes a car to start after disconnecting and reconnecting the battery?

The most likely reason why your car starts after doing this is that the battery was not properly connected in the first place. When you disconnect and reconnect the battery, it allows the electrical current to flow more freely and thus start your car.

Another reason could be that there is corrosion on the battery terminals. This can happen when the battery is old or if it wasn’t maintained properly. The corrosion can prevent the electrical current from flowing freely, but disconnecting and reconnecting the battery can clean the terminals and allow the current to flow again.

In some cases, a car may not start after disconnecting and reconnecting the battery because there is an issue with the starter or alternator. If this is the case, then simply reconnecting the battery will not fix the problem and the car will not start.
