Does Revving the Engine Charge the Battery Faster?

Car battery and engine are essential in igniting the vehicle. Sometimes the vehicle battery may fail to charge or charge slowly, thus preventing the car from starting. In such cases, some people may consider revving the vehicle engine to charge the battery faster, enabling the vehicle to run normally.

Revving the engine to charge the battery faster has many advantages, including enabling the vehicle battery to charge faster, among others. This article describes why it is safe to rev the engine to charge the battery faster, tips to be followed during the revving process, and a step-by-step guide on how to rev the engine charges the battery faster. Ensure you have complete knowledge of the tips and the steps to avoid damaging the vehicle battery.

Yes. Revving the car engine to charge the battery faster is possible but only in a specific condition when the car battery discharges significantly. Most manufacturers have added automatic features to keep the car battery wholly charged when increasing efficiency and effectiveness. The automatic features also prevent the car battery from discharging continuously and dying.

Most car batteries, such as lead-acid batteries, usually use amperage, which the car alternator provides when not in use. The condition applies when the car battery discharges and reaches a low battery state. Once the battery gets a low state of charge, it receives more amperage compared to when the vehicle alternator is not in use.

If you start revving the car engine, the battery will charge faster since the vehicle alternator provides more amperage. The vehicle alternator runs faster when the car engine is turned on hence increasing the charging speed on the car battery. When revving the car engine, consider the vehicle battery’s state and ensure it is significantly discharged as recommended by the manufacturer or a professional mechanic.

Guidelines on how to revive the vehicle engine charge the battery fasterGuidelines on how to revive the vehicle engine charge the battery faster

Before revving the car engine to charge the battery faster, consider some factors such as the temperature of the vehicle engine. Ensure the vehicle engine is at the recommended temperature, especially after jump-starting the vehicle.

To rev the vehicle engine charge the battery faster; follow the steps below

 Step 1: Switch on the vehicle

First, check the car battery’s condition before switching it on to ensure it is in good condition. If the battery is in good condition, switch on the vehicle and turn on the engine. After turning on the engine, put the car in a neutral state instantly. If the vehicle battery is dead, consider jump-starting it using recommended steps before switching it on.

Step 2: Leave the vehicle engine running for a couple of seconds

After starting the engine, leave it for approximately 30 to 60 seconds running before revving the car. Leaving the engine idle enables the oil to move freely and circulate in each end evenly. Also, the oil present in the car engine increases efficiency and prevents the vehicle engine from being damaged.

But, if there is no oil in the engine, consider refiling the engine with oil using an oil filter. While refilling the engine, ensure you check the maximum level to avoid overflowing the engine with oil. Finally, refer to the manufacturer’s manual book on the recommended oil for your vehicle model to avoid damaging the engine with the wrong engine oil.

Step 3: Click the vehicle accelerator pedal

The next step is revving the vehicle engine to charge the battery faster. First, locate the position of the accelerator pedal. Press the pedal gently for some time until the tachometer’s needle changes its position and comes on the red end of the car gauge. Ensure the needle turns effectively to obtain accurate results.

In all vehicles, the needle on the red is a sign of your car reaching high safe engine speed, and the engine speed differs from one vehicle to another depending on the model and the manufacturer. Therefore, it is essential to ensure that the needle is displayed on the red end of the gauge and if not, consider repeating the process carefully until it shows on the red end of the gauge.

Step 4: Idle the vehicle engine

After successfully revving the car engine, charge the battery faster, release the pressure present in the accelerator pedal slowly and leave it for seconds until the engine goes back to its idling state. Check the battery if it is charging; if not, consider repeating the process or seeking help from a nearby licensed repair shop.

Ways of increasing the lifespan of the vehicle batteryWays of increasing the lifespan of the vehicle battery

Sometimes revving can hurt the engine if the vehicle is revved when the weather is freezing and in its neutral state. In such a situation, consider warming up the car engine to reduce the risk of engine harm, and warming up is only applicable in good state batteries, unlike dead batteries.

There are several ways of increasing the lifespan of the vehicle battery more than the estimated time and are shown below.

  • Keep the vehicle batteries away from high temperatures, especially when the car is not in use. Extreme temperatures, either too hot or too cold, reduce the battery’s efficiency, thus reducing its lifespan.
  • Service the battery at least thrice a year. Take the battery to a professional mechanic to test it for you, see if it is in good condition, and resolve any immediately detected issues.
  • Examine the battery and its terminals carefully. Clean them if there is an accumulation of dirt, rust, and dust. Cleaning the terminals prevents the occurrence of metal corrosion that may prevent the proper functioning of the battery.

When cleaning the terminals, use natural home remedies to avoid damaging them. First, boil 240 ml of water and place it in a clean container. Add 10 ml baking soda into the container and mix it well to obtain the best solution. Using an old toothbrush, scrub the battery terminal evenly until they are completely clean. Rinse them and leave them to dry completely. While cleaning the terminals, first, ensure the car is in idle mode, and the engine is cold enough to prevent the terminals and water from corroding or prevent electric shock, among others.

  • When the vehicle headlights are not in use, ensure you turn them off to avoid draining electricity from the battery.

Steps on how to charge the vehicle battery without revving the car engine to charge the batterySteps on how to charge the vehicle battery without revving the car engine to charge the battery

If the car battery is not charged, the engine fails to ignite, and you will remain stranded unless you seek help from a nearby skilled mechanic. To charge the battery without revving the engine requires the following steps.

  1. Collect all materials required. The materials required include; a car battery charger, voltmeter, recommended wire brush, and an extension cord. Some tools, such as the recommended wire brush and voltmeter, are optional if you don’t have any tools.
  2. Switch all vehicle accessories such as headlights, a radio that may drain energy faster. Check the state of the battery using a voltmeter.
  3. Check the status of the battery charger and the battery terminals. Ensure they are in good condition before charging the battery.
  4. Connect the battery to the power supply source using a smart battery charger that matches the vehicle model.
  5. Leave the battery to charge and test it to see if it is fully charged. If fully charged, disconnect the battery from the power supply source and start the car. If the vehicle fails to start, seek help.


Revving the engine charges the battery faster, especially when the battery is discharged. To rev the engine, charge the battery successfully, follow the steps above carefully to increase the amperage produced by the alternator.

Finally, ensure you follow the manufacturer’s instructions on how to rev the engine and charge the battery. If the engine fails to charge the battery, seek help from a professional mechanic and remember to service the battery at least twice a year.
