Right Way To Disconnect A Car Battery. Disconnect the positive terminal of the battery 6. I cant see how this would matter.
Look for a black cable and a minus - symbol. Pull the negative connector from the battery after youve loosened the nut. A friend of mine told me that I should always disconnect the positive terminal of the battery first to keep the electricity from spilling out of the battery.
There will be an 8mm fastener.
Start with the negative terminal and disconnect the negative battery cable. Never ever try to disconnect the battery of your car without first turning the ignition off. Make sure you get good contact and slide the positive cable the rest of the way on. There will be an 8mm fastener.
