Secondly, ensure to have a good connection. You may have a spark when connecting the last clamp of the jumper cables. Wiggle the jumper a bit for the teeth on the cable to clean the metal off to create a good contact.

Thirdly, exercise patience. If you have thick and high-quality jumper cables, it should take a few minutes to transfer enough power to start the car. If the battery of the car you are jumping is completely dead, it can take a little longer.

The power transferred to the flat battery is being used each time you try to start the car, which also adds more time till it starts the engine. Therefore, give it a few minutes before jumping the car.

If the engine sounds close to starting, wait for some minutes before jumping again. If it does not sound closer to starting, you have to wait even longer.

Ensure to wiggle the jumper cables after each attempt to start. The additional power drawn trying to start the car may result in a weak cable connection losing connection. You can wait up to 5 minutes to jump the dead battery.

Charging your flat car battery

While a portable jump starter and another car with a good battery will jump your car and save time, it is more advisable to charge the battery.

Have your local auto parts store charge the car battery. This reduces the possibility of straining other vehicle components. The alternator of your car charges the battery while it is running. So, be sure that the alternator is not faulty. Otherwise, you will just have to jump the car battery again minutes after turning off the engine.

If the car battery will not hold a charge, and you find yourself jumping the battery multiple times, consider buying a replacement battery.

If the new battery keeps draining, have the mechanic diagnose the car for an underlying issue. You should consider driving on a different battery that is in good condition to know if it is a battery problem or car component problem before buying a new car battery.
