How to Jumpstart a Car Safely — Complete Step-by-Step Guide
Dead battery and no idea what to do? Learn exactly how to jumpstart a car safely — correct cable order, common mistakes that damage electronics, portable jump starter tips, and what to do when it doesn’t work.
To jumpstart a car: Connect red cable to dead battery positive → red cable to good battery positive → black cable to good battery negative → black cable to unpainted metal on dead car (not the battery). Start the working car, wait 3 minutes, then start the dead car. Never connect black to dead battery negative — this risks a spark near battery hydrogen gas.
