Step 7: Disconnect the Cables
Once the dead vehicle is running, carefully remove the cables in the reverse order of attachment:
- Remove the black cable from the unpainted metal part of the dead battery.
- Remove the black cable from the functioning battery.
- Then remove the red cable from the good battery.
- Finally, remove the red cable from the dead battery.
Step 8: Allow the Revived Battery to Charge
Keep the revived vehicle running for at least 15 to 30 minutes to help recharge the battery.
Final Thoughts
Jump-starting a car can be a straightforward task if conducted safely and with proper technique. The key takeaway here is that connecting two jumper cables is not a wise decision and should never be attempted. Instead, always use one set of cables and adhere to the correct procedure.
Additional Tips
