Charging a car battery with a wall outlet is not as difficult as it seems. Here are some tips to help you do it:

  1. Make sure the outlet is properly grounded. This will help protect your electrical equipment from being damaged by the battery.
  2. Connect the negative (-) wire of the battery to the grounding wire of the outlet, and connect the positive (+) wire of the battery to the outlet’s power cord.
  3. Plug in the outlet and wait for it to charge the battery. The charging process will take about an hour or so.
  4. When charging is complete, disconnect the outlet from both batteries and let them sit for a few minutes so that they can cool down before using them again.
