An automobiles battery provides the electricity necessary to start the car and to run its electrical equipment. Although an automobile battery is normally charged by the cars alternator while the car is running, there are times when the battery dies for various reasons and needs to be connected to a charger. When jumpstarting a car you essentially give the dead battery just enough boost to start the engine and then rely on the alternator to charge the battery the rest of the way. When using a battery charger, you allow the battery to charge all the way before it will be used again.

If Your Car Battery Is Above 12 Volts Go For A Drive

In general, if the battery is showing between 12 and 12.4 volts, its safe to recharge it using your vehicles alternator. That means driving around using as little electricity as possiblestereo system off, lights off , and all heating and cooling functions offto make sure that the alternator is sending as much energy into the battery as possible. Youll also want to keep your vehicle above idle as much as possible, as higher revolutions will pour more power into the charging circuit. Aim for at least a 30-minute drive to get the battery back to a safe level for your next start.

Follow The Instructions Below:

Step 1: To model a charger for a real car battery, the first thing you need to do is create something that acts as its positive and negative pole. You can use two new wires and cut the rubber parts at both ends to expose the wire inside. Then form a circular loop with wires that you can use by twisting around the nodes of the power cell.

Step 2: For a temporary negative cable from your charging system, create loops at both ends of the cable. For one that will act as your positive wire, loop one end and leave other end as it is. To avoid confusion, you can label cables or use a color code to indicate their polarity.

Step 3: Using the negative cable, wrap the loop around the plug of the charger.

Pull the wire around the metal part of the assembly, and then seal it tightly with electrical tape.

Step 4: Then take the positive cable, try to make it bulky, and thicken the wires. Then apply some aluminum foil along the entire length of the wire. This will be a component of your charging system, which you plug into the opening of the charger .

NOTE. The structure should be like this: a small metal tube will have a positive cable inside, and then the negative circuit will hug it outside. You must also ensure that your positive cord is firmly compressed inside to avoid sparks.

Start The Working Vehicle

Now, get into the working car to start it. Carefully ignite the engine and let it run for around 5 to 10 minutes to pass current to the dead battery through the cables.

After 5 to 10 minutes, shut the engine off and get into the dead vehicle to start it. It should start. After starting the engine, let it run for 5 to 10 minutes and in the meantime, disconnect the cables.

After disconnecting the cables, drive the vehicle that had a battery drain out problem for 2 to 3 hours to fully recharge the battery.

How to Charge a Car Battery Without a Charger?

Hook up the lights to the power supply so that when you start the charging process, the lights will come on to confirm that there is a current flowing between the supply and battery. Without the lights, you might wait for hours wondering if its working but with no luck. The bulb/lights have an additional function here, which is to draw the bulk of the current so that you can maintain a safe trickle into your car battery. This helps prevent overcharge damage.

What Does A Car Battery Do

Why is the car battery important and why should you ensure it is always charged? First, the car battery ensures the motor can turn over and start. When you put your key in the ignition, the battery is responsible for delivering the voltage needed to activate the starter.

Additionally, the automotive battery provides voltage to the engine while it is running and powers up your important accessories. Without it, you wouldnt have headlights, a car radio or anything else electronic in the vehicle.

Can You Overcharge A 12 V Battery Using A 10 Amp Charger

Yes, you can overcharge a 12V battery with a 10 amp charger that constantly charges with a peak current of 10 amps regardless of what state of charge your battery is.

Use a good quality 10 amp smart battery charger and maintainer suited to your battery type that makes adjustments to the actual voltage and current to avoid overcharging and damage to the battery.

A Few Things You Should Know First

Charge your car battery without losing your settings!
  • You can trickle-charge every single battery that was or will be ever made.
  • Trickle-charging uses a low current, which means it is very good for your batterys lifespan.
  • Small bulbs like flashlight bulbs or the ones you hang on your Christmas tree every year will make excellent current regulators.
  • Some batteries will have 3 terminals that are labeled +, , and T. At this point, you probably already knew what + and are. So what does the T on the other terminal mean? Well, T stands for my name Timmy of course!
  • Just kidding! Actually, its called a Thermistor a sort of temperature sensor. Sometimes it is used to regulate charging current, sometimes just for safety. And now with that out of the way, lets get started on things you will need to prepare.

    Solution : Charge Directly With A Power Supply

    Most lead-based batteries can be effectively charged directly from a power supply provided it features current limiting and adjustable voltage so your boy/girl may also be in luck if you have a functional power supply.

    The first task is determining the charge voltage and then set the required voltage as well as the current limit.

    For instance, to charge a 12-volt power wheels battery, you need to set the power supply at over 12V,2A to charge- the battery chemistry determines the maximum but its mostly around 13.8V,2A .

    A similar scenario plays out for a 6-volt power wheels battery. Go over 6V,2A but limit the charge current if you have to overshoot the standard 6.8V,2A.

    I recommend that you consider adding a resistor to be on the safe side just in case the battery fails to withstand the set current.

    There could be variations needed in your case because power wheels batteries are not built the same but in general, this should help you charge seamlessly.

    Having said that, you wont take your eyes off the batterys temperature, current, and voltage during charging unless you dont mind losing the entire setup.

    How To Tell If The Power Wheels Battery Is Charging

    One way is to use a smart charger, as the charger that comes with the battery cannot test the batterys charge. But be aware that a smart charger wont always provide you with the right results. It can occur when the battery in your childs toy car has been sitting idle for a few months.

    Also, it is a good idea to use a smart charger to verify if the battery has any power or not every 2 or 3 months.

    But the quickest way of telling if a Power Wheels battery is charging is to connect it back up to the toy in which it is used. Then see if the toy will start or not.

    The Basic Concept And Risks Of The Automatic Battery Charging Process

    Charging a car battery with a real charger is the safest and most effective way to do this. So the best and most popular alternative is to charge the power element with another car.

    Keep in mind that this method is a “solution,” an innovative improvisation that carries risks. This method is not recommended unless the situation requires it, and you have no other options.

    The idea of this alternative method is to use any charger with the same voltage potential as a car charger. Then use some materials that you can usually find at home to create a home-made charger that you can use to charge your car’s battery until it reaches its maximum electric capacity.

    NOTE. If you decide to use this temporary method to charge your car battery, be sure to wear protective equipment and carry it out with extreme care.
