Which battery post to remove first?
One commonly asked question is which battery post to remove first: the positive or the negative. Every battery has two terminals: a positive terminal and a negative terminal. The positive terminal is usually marked with a plus sign (+), while the negative terminal is usually marked with a minus sign (-).
Do you disconnect a battery before a positive?
However, DO NOT disconnect the positive terminal before the negative one. Doing so can cause an electrical short. Always disconnect the negative battery terminal first. What happens if you disconnect the battery before the positive? Therefore, carefully remove the negative battery terminal first before the positive terminal.
What is the correct procedure for removing a battery?
The correct procedure for removing a battery is to always disconnect the negative terminal first. This is usually indicated by a “-” sign or the letters “NEG” on the battery or terminal. Removing the negative terminal first helps prevent any short circuits or sparks that could occur if the positive terminal is disconnected first.
Which terminal should be removed before removing a battery?
When removing the battery, it is recommended to disconnect the negative (black) terminal first. This is done to prevent any accidental short circuits and ensure a safe removal process. Once the negative terminal is disconnected, you can proceed to remove the positive (red) terminal. Disconnecting Battery: Which Terminal to Remove First?
