Simply put, revving the engine of a car is turning the ignition and allowing the engine to run on its own without coercion or applying any pressure on the gas pedal.

Revving a vehicle for some time, particularly in the morning is important because it allows the engine to warm up and get oil to circulate in all its crevices that are prone to friction.

It is a common practice for drivers to attempt hurrying the process of engine revving by putting pressure on the gas pedal.(Read Also: How To Charge A Car Battery With A Laptop Charger)

This is wrong because as you do this, you are causing certain parts of the engine to forcefully work against friction even when they are not lubricated enough, which has the tendency to cause great wear and tear of engine components such as the rings, cylinder walls, the valves, the crankshaft, the bearings, and many others.

It is therefore easy to see why doing this is associated with regular and premature replacements of vital engine parts.

Does Revving The Engine In Neutral Charge The Battery? So Does revving the engine in neutral charge the battery? After turning on the ignition, the engine of the car spurts to life and as its parts run, a jolt of electricity is sent to the alternator which transmits part of these charges to the battery.

As the battery receives these charges, its voltage appreciates which is referred to as charging. Essentially, therefore, so long as this cycle is executed even when the car is in neutral, the battery will get charged. That means revving the engine in neutral charges the battery as it should.

Is Revving The Engine Bad?

Revving the engine on its own is not really bad, so to say, and can in fact be beneficial to the engine in some instances, but it has to be done correctly.

This means that if you must rev the engine, allow it to run of its own accord without putting any pressure on the gas pedal which will otherwise enforce the process, a practice that is quite capable of destroying your engine. (Read Also: How To Charge A Car Battery With RC Battery)

Furthermore, it is not very advisable to rev the engine too frequently as that is also injurious to the engine. You should also not rev your engine if it is on a rev limiter as that has the tendency to affect your engine gravely.

How Many Revs Does It Take To Charge A Battery?

The number of revs it takes to charge the engine is not a specific thing per se since it may vary slightly from vehicle to vehicle, even among cars of the same model.

However, it is generally known that revving the engine at about 1500 to 2000 RPM (revolutions per minute) will suffice to charge your battery.

It will do well to understand that if you run the engine at this speed for a reasonable length of time like a few minutes, you stand to get your battery charged more than when you do it for a shorter period.

What Happens If You Rev Your Engine In Neutral?

It does not matter how you rev the engine whether in neutral or in the park mode. What is actually important is whether you do it correctly or not. In essence, you stand to gain equally whichever way you rev the engine because eventually the battery will effectively get charged,  one way or another, but be sure to do it correctly.

Can You Charge A Car Battery In Neutral?

What Happens If You Rev Your Engine In Park?

Nothing out of the ordinary or special will happen if you rev the engine in park mode. Essentially, nothing different happens when you rev in the park than it does when you rev in neutral or in any other gear, for that matter.

Whichever way you do it, the battery will essentially get charged and the engine components will be gradually lubricated as they should. The overall result of which will be a smoother and more efficient running engine.

Why Does My Engine Rev When I Accelerate?

Naturally, your engine is bound to rev when you accelerate because as you do that,  the components of the engine move faster and progressively attain higher revolutions per minute.

This will basically cause the engine to rev much more than when it is running at a lower RPM.

Why You Should Not Rev Your Engine?

There is really nothing wrong with revving your engine whether first thing in the morning before going out or later in the day or even finally at night after your activities have been concluded. In fact, your engine stands to benefit more from revving than would otherwise have been the case.

What actually matters is how you go about the entire process; while revving, allow the engine to run quietly and smoothly of its own accord without tempering with the gas pedal.

In this way, as the engine runs, its temperature builds up and lubricating oils begin to circulate all through the engine parts which makes the engine smoother and healthier.

In addition, do not rev the engine of your car as long as it is on a rev limiter. Doing this will likely have grave effects on your engine.(Read Also:How To Test A 12-Volt Battery Charger?)

What Should I Know Before Jump Starting A Car Effectively?

The ability to jump-start a car is an indispensable skill to every driver as you stand to gain from it much more than from any other motoring skill.

  • Rubber work gloves
  • A pair of splash-proof polycarbonate safety goggles meant for an auto repair
  • A wire brush and another vehicle with a fully charged battery that is of the same voltage as your own.

The Do’s Of Jump Starting A Battery

Before you attempt to jump-start any battery, read the user manual thoroughly because there are variations in terms of how you connect the necessary cables among different cars, and reading the owner’s manual will significantly help. (Read Also: How To Push An Automatic Car With Dead Battery)

In certain instances, some car manufacturers do not permit battery jump-starting, which means that should you attempt any such endeavor, you are in essence voiding your warranty agreement.  You should also verify the voltage of both the battery you want to jump start as well as that with which you plan to do it.

In case of any mismatch, do not proceed any further as serious damage can be done to both vehicles. If up to this stage all is perfect, then you should proceed to park the cars as close to each other as possible so that the cables will reach where they are wanted, but make sure that they do not touch.

The engine of the car with a good battery should be turned off and also unplug all accessories such as phones, radios, AC, and so on. If you do not do this, the power surge during the jump start may short them out. Both the cars that will be used must be parked in neutral and the parking brake engaged. Finally, put on rubber gloves and safety goggles before you start the process.

The Don’ts Of Jump Starting A Battery

Just like there are certain things to do before you attempt any battery jump-start, so do you have things that must not be done. For instance, do not lean over the battery of either car or smoke while jump-starting a battery. In addition, do not jump-start a battery that is leaking or from which fluids are oozing, as that can trigger an explosion.

Pre-Checking Prior To Jump Starting Any Battery

Make sure that you know where the batteries of both cars are and determine the polarity of their terminals correctly. The positive terminal has a (+) sign and bears red-colored wires or cover, while the negative terminal has a (-) sign and takes black-colored wires or cover. Clean terminals that are either dirty or covered with corrosion.

The Actual Jump-Starting Of The Battery

  • To jump-start, create a circuit that carries current from the live battery to the dead one, and to do that properly, connect the cables as follows: connect one end of the red jumper cable of one car to the red positive pole of the dead car battery.
  • Also, connect the second end of the red positive jumper cable to the red positive post of the fully charged car battery. Next, connect one end of the black or negative jumper cable to the black negative post of the fully charged car battery.
  • Thereafter, connect the other end of the black or negative jumper cable to an unpainted metal part of the dead car as far away from the battery as the cable will allow. This will ground the circuit and also prevent any spark from flying.
  • Connecting this wire directly to the dead battery carries the risk of explosion. Ensure that none of the cables are touching any engine parts which may move when the engine is turned on.

Final Step

You can complete jump-starting a battery in any of two ways. The first one is to start the car with a good battery and allow it to idle for about five to ten minutes so that it will charge the dead battery. Then turn off the engine and remove the connecting cables in a reversed order without allowing the cables to touch.

Now, attempt to start the car with the dead engine. The second method involves starting the car with the charged battery and letting it idle for about five to ten minutes so that the dead battery can be charged.

Then, attempt to start the car with the dead battery without shutting off the fully charged car, if the car with the dead battery refuses to start even after repeated efforts, re-adjust the red or positive cable in the hope of getting a better connection.

Then try to jump-start again and if the dead car starts, remove the cables in the reversed order you put them on at the beginning while always ensuring that the cables do not touch.
