What is when connecting a battery which terminal first?

When connecting a battery, it's generally recommended to connect the <a href="https://www.wikiwhat.page/kavramlar/positive%20terminal">positive terminal</a> first. This is to minimize the risk of a short circuit.

Here's why:

  • Connecting the positive terminal first allows you to then connect the <a href="https://www.wikiwhat.page/kavramlar/negative%20terminal">negative terminal</a> to the chassis (ground) of the vehicle or device.

  • If you were to connect the negative terminal (ground) first, and then accidentally touch the positive cable to the chassis while connecting it, you could create a direct short circuit. This is because the chassis is already grounded. This can lead to sparks, potential damage to the battery or vehicle, and even injury.
