It’s great to hear you’re cleaning your battery—a lot of people don’t know they need to!
When it comes to car insurance and car batteries, everything needs to be squared away to work correctly. For your safety and to ensure your car isn’t damaged, you’ll need to know how to properly disconnect and reconnect the cables to the battery terminals.
When you need to disconnect the battery terminals, start with the negative cable and then the positive cable. However, you’ll do the reverse when you reconnect the cables to the battery—connect positive, then negative. This order will keep you safe and prevent damage from occurring to the battery.
