  • Ensure that your surrounding is totally dry along with your dry hands or legs.
  • Properly read the manual of the battery charger.

  • Keep your battery charger disconnected from home electricity (power supply).
  • Now connect the negative wire (black wire) of the charger with the negative terminal of the battery.
  • Then connect positive wire (red wire) of the charger with the positive terminal of the battery.
  • Finally plug-in your charger with home electricity.
  • You have done all the connection and your battery is charging now.

Step 4: Monitor Charging

Your battery is charging and you can see charging current and voltage on the battery charger. If you are using an old charger then you have to keep on monitoring charging current and when it comes to zero then your battery is fully charged.

But if you are having a modern charger then it will automatically give an alarm to you whenever your battery will charge. A normal battery takes 8-10 hours to get fully charged. If your charger gives an indication of full charge within 3-6 hrs then your battery is needed to be replaced.

Once your battery is fully charged then switch off the charger and remove all the connection of the charger. Now your battery is ready to use in your car.

  • Keep your both vehicles in shut off ignition positon.
  • Now Attach one Red clip of jumper cable with the positive terminal of the fully charged battery. Attach another terminal of the same cable with the positive terminal of the dead battery.
  • After that attach the black clip of jumper cable with the negative terminal of the fully charged battery. Similarly, attach another terminal of cable with the negative terminal of the dead battery.
  • Give a crank to your car that is having a fully charged battery and keep it ON mode.
