What Causes a Car Battery Terminal to Get Hot When Trying to Start It?
When you try to start your car, the battery terminal may become hot to the touch. This is usually caused by a poor connection between the battery terminal and the cable. When the connection is poor, the resistance between the two parts increases, which causes the terminal to heat up.
There are a few things that can cause a poor connection between the battery terminal and the cable. One common cause is corrosion. Over time, the metal on the terminal and the cable can corrode, which creates a barrier between the two parts and prevents them from making a good connection. Another common cause is a loose connection. If the cable is not properly tightened, it can move around and create a poor connection with the terminal.
If you notice that your battery terminal is getting hot when you try to start your car, you should first check the connection between the terminal and the cable. If the connection is loose, you can tighten it using a wrench. If the connection is corroded, you can clean it using a wire brush or a battery terminal cleaner. After you have cleaned or tightened the connection, try starting your car again. If the terminal is still getting hot, you may need to replace the battery cable.
