How Long to Recharge the Car Battery After the Jump?

Most people prefer driving their cars each day without caring and regularly maintaining them to increase their lifespan, especially the car battery. Improper maintenance of the car battery can affect the charging status of the lifespan and makes the battery drain power faster than usual.

The battery may be charged if not completely dead, but it is difficult, and the results may not be positive in most cases. Therefore, it is advisable to try charging a car battery after the jump before replacing it. The article below describes how long before recharging the car battery after the jump.

Switching on the car engine using an ignition key but the car fails to respond can be stressful, especially when late for the job. It is a common problem for the majority of people owning personal cars. In such a situation, first, inspect the car battery’s condition if it is charging or dead.

If the car battery switches to jump mode while driving, try driving the car for a few miles to allow the battery to recharge and store enough energy to start the car. Also, wait for a couple of minutes before charging the battery to get accurate results.

Ways of recharging the car battery after the jump

Despite bringing a dead battery to life difficult, several methods may recharge the car battery, such as using the car alternator, using an appropriate battery charger, among others. The information below describes how to recharge a car battery after a jump start.

1. Recharge the battery using a car alternator

How Long To Recharge Car Battery After Jump

Even though charging a battery in jump mode is difficult, the car alternator might seem to be the best solution for those willing to bring the battery to function. The car alternator performs two functions; first, it maintains the battery when fully charged, and also it supplies energy to the car parts such as radio and lights. The alternator only maintains the battery when fully charged but not charging the car battery until complete.

The car alternator also supplies power in case of emergencies without supplying an ample amount of current. Frequent use of the car alternator may negatively affect itself and the car battery, especially for the weak car batteries that keep switching to “jump mode” frequently. Also, a poor battery can damage the car engine, mainly when too much current is supplied to the engine, which the motor cannot withstand.

Therefore, it is crucial to test the car battery using a multimeter, regulator, or screwdriver to see the magnetic attraction before recharging it. Also, you may use a load tester to test if you don’t have any tools stated above. If the battery is faulty, replace it and proceed to recharge it. Finally, when handling the car battery, maintain and service it regularly to prevent it from running flat.

2. Recharging the car battery using a chargerRecharging the car battery using a charger

Recharging the car battery using the correct charger after a jump start is easy as long as you have a well-functioning charger. The most preferred chargers for recharging batteries in “jump mode” include; a smart battery charger and an advanced trickle charger. The advanced trickle chargers have a feature of automatically switching off once the car battery is fully charged. Most people prefer recharging a dead battery using a smart battery charger due to the following reasons;

  1. They have a protection feature that automatically switches off once the battery is complete to avoid damaging the car battery.
  2. The smart chargers maintain a fully charged car battery as it has a maintenance feature.
  3. Help in bringing back to life a dead car battery as the charger contains deep cycle mode.

Using an advanced smart charger for recharging the car battery after jump start differs depending on the model of the car, size, and the amount of power the smart charger may withstand. To recharge a dead battery, follow the steps below;

  1. Access a car battery charger of high quality, such as an advanced smart charger that may revive the dead battery. Ensure the charger is functioning correctly and is in good condition.
  2.  Find the location of the battery charging port and connect the battery to the charger.
  3.  Connect the charger to the power supply source. Ensure the terminals match each other; that is, the black cable matches the black cable and the red wires of the charger to those of the battery. Ensure the connection is not loose and not too firm but the recommended ones.
  4. Switch on the power supply source to allow power to be transmitted to the battery to “wake up” the dead battery.
  5. Leave the battery to charge until it is complete. The dead battery may take up to 12 hours to completely charge. During the charging process, inspect the dead battery frequently to ensure it is charging and if not charging, consider testing the status of the car battery and replace it if it is a fault.
  6. Test the battery to see if it is functioning normally. If not, try repeating the process above but if the problem persists, contact a professional mechanic to help you identify the problem and fix it immediately. Therefore, it is advisable to use an advanced battery charger rather than other chargers to get positive results.

Guidelines on how to prolong the lifespan of the car battery

Guidelines on how to prolong the lifespan of the car battery

The car battery’s expiry date is usually indicated on the side, top of the car battery showing the manufacturing and expiry period. Despite the maximum number of years, a well-maintained car battery may last longer than a poorly maintained battery. The following tips show how to increase the battery’s lifespan.

  • Frequently inspect the alternator belt and solve any belt problems detected. If you don’t know how to check the alternator belt, seek help from the manufacturer or a nearby mechanic. Also, you can use search engines to gain more knowledge on the car alternator belt.
  • If you don’t use the car frequently, ensure you disconnect the battery when not used and keep it in a cool, dry place. Most car batteries drain power even when all car parts are switched off, leaving the battery in “dead mode”.
  • Use an advanced smart charger when charging the battery to keep it fully charged and protected from overcharging since it automatically turns off once the battery is full.
  • Clean the battery terminals often to remove any rust and dirt that has accumulated on the surface. Rust and dirt prevent the car battery from charging correctly, preventing the car engine from starting during the ignition process.
  • When charging the car battery, turn off all car parts that use energy, such as light, radio, air conditioning, among others.

Frequently asked questions:

  • How long can I drive my car after “jump mode”?

Drive the car for about thirty minutes for the battery to recharge before stopping. But if the car fails to start during ignition, run the engine for a couple of minutes.


A dead car battery affects the normal functioning of the car. For instance, the car may fail to ignite due to insufficient or no power supply to the car engine that will start the car. If you experience such problems, first, inspect the car battery’s condition to ensure it is functioning well. If the battery is dead or is in “jump mode,” consider recharging it using an advanced smart battery charger.

Finally, if the car is not in use, ensure you switch all car accessories that may drain energy and disconnect the battery and store it in a cool, dry place until when needed. Also, test the battery frequently to keep it in good condition, especially when not in use. Finally, maintain the car battery to prolong its lifespan.

Jump start a Car. Anyone who drives should know how to safely jump start their car because one day your battery will be dead. Whether you left your lights on or your battery goes bad, knowing how to jump your car safely and properly will keep you from getting stranded.
