The Proper Steps: How To Jumpstart A Car

How to charge a dead car battery… without another car to jump you off.

Surely, you will get a drained battery when you go for an extended vacation without your car, or leave your headlights on. So you have to know how safely and properly jumpstart a vehicle because its effortless to work, and you do not need to hire any technician.

Step 1: Open Up the Hood

First of all, take the ignition keys for both cars. Then, open the hood and clean all the dirt from there. Check the battery position for both cars and find the red positive and negative terminal.

The positive red cables will be red and the negative are black. Different colors play a vital role in understanding connecting positive and negative battery terminals. Also, check carefully for the complex sections like car AC compressors, carburetors, and others while checking stuff.

Step 2: De-Tangling the Cable

Now take your jumper cable and hold red and black cable each hand. Detangle the wire so that you can connect them easily.

The jumper cables should be connected so that it wont end to touch each other. Also, the donor battery should have enough voltage and matching voltage system.

Take one side of the jumper cables, like the red cables, which are red positive. Now attach it to the positive side of the dead battery.

The need for a better cable is important in any kind of situation, whether you want to wake up the dead cells of double the winch battery power. You need a solid connection.

Step 4: Connecting the Black Wire to the Dead Cell

Is It Safe To Charge A Battery

This is a common question, and the answer is not as simple as a yes or no. It depends on the type of battery, how it is being charged, and what type of charger is being used.

Lithium-ion batteries are the most popular type of battery today. They are used in cell phones, laptops, and many other types of portable electronic devices. Lithium-ion batteries are safe to charge, but you must use the proper charger.

Some lithium-ion batteries are not meant to be charged with a standard charger. These batteries have a built-in protection circuit that prevents them from being overcharged. If you use the wrong type of charger, you could damage the battery or cause it to catch fire.

If you are using a standard charger, you can charge your lithium-ion battery safely. Just be sure to follow the instructions that came with your device.

Nickel-cadmium and nickel-metal-hydride batteries are not as popular as lithium-ion batteries, but they are still used in some devices. These batteries can be charged safely with a standard charger.

Some people believe that it is not safe to charge any type of battery. This is not true. As long as you use the proper charger and follow the instructions that came with your device, you can charge your battery safely.

How To Charge An Extra Battery While Driving A Car

Charging an extra battery while driving a car is easier than you might think. For years, RVs have done this–charging a “house” battery for use when the engine was off by using a battery isolator that allows the charge, but also protects your main battery. The main thing to consider is where to place your extra battery once you have decided, you can install a system for charging an extra battery in about 20 minutes.

Step 1

Disconnect the cable from the negative post of your main battery.

Step 2

Place your extra battery in your vehicle and attach battery tie downs to hold it in place. Use existing bolts for an anchor for the tie downs or drill and attach the tie downs with sheet metal screws.

Step 3

Attach the battery isolator to the firewall of your engine compartment. If you cannot find an appropriate size bolt/screw to “piggy-back” off , drive a sheet metal screw with a drill into the car frame to attach the isolator.

Step 4

Trace the wire from the battery post on the alternator to your car’s fuse box. On the opposite end of the fuse the alternator wires to, attach a wire and run this to the post marked “IN” on the battery isolator. Strip and crimp a ring connector on the end of your wire to attach it to the post, rather than coiling bare wire around the post your connection will be more reliable this way.

Step 5

Attach a wire from the “OUT” post on the battery isolator and run it to the positive post of your extra battery.

    How Do You Charge One Battery From Another

    There are a few ways to charge one battery from another, depending on what type of batteries you are using. If you are using two AA batteries, you can connect them in series by connecting the positive terminal of the first battery to the negative terminal of the second battery. This will cause the batteries to charge each other. If you are using two AAA batteries, you can connect them in parallel by connecting the positive terminal of each battery to the positive terminal of the other battery, and connecting the negative terminal of each battery to the negative terminal of the other battery. This will also cause the batteries to charge each other.

    Charge Without A Battery Charger

    Nothing has worked out for you so far? I can understand. There come situations when your car battery gets dead and the charger remains absent.

    You dont need to worry, here are some of the ways to charge your battery at home as well!

  • First Method:
  • If you have a laptop, then its charging adapter can help you fix the battery issue. The adapter can usually provide an output of 18-19 volts.

    Thus, along with the adapter, take a 12-volt bulb with power ranging from 5-50. However, it is important to note that the higher the power of the bulb the higher the charging current.

    But, for the safe side do not raise the power more than 3.5 or 4 amp. Connect the entire scheme in series and hook a multimeter to have a constant display of the value of current passing through.

    2. Second Method:

    For this method, take a bulb of 220/110 volts, 40-100 Watts. The lamp works as a current limiter and then attaches the diode and lamp in series. Make sure to connect the neutral wire of AC to the negative terminal of the battery with the help of a voltage tester.

    Connect the last end with an AC adapter and let the circuit charge the battery for restored functioning.

    3. Third Method:

    This method is similar to the previous one except that the diode is replaced by a diode bridge . Want to know where to get that from?

    Well, you can remove a suitable bridge from an unused computer desktop. However, please understand that it might be dangerous for electric shock.

    How Long To Charge A Car Battery


    Fully charging a battery with a charger could take anywhere from a couple of hours to a couple of days, depending on the strength of the charger and the battery’s voltage. While a partially charged car battery will still allow you to drive your car, at least for a short distance, you run the risk of starting this process all over again if you don’t wait for a full charge.

    If you use jumper cables, don’t turn the engine off right after the jumpstart. Instead, cruise around for at least 15 minutes so the battery can continue charging. Kill the engine too soon and you could find yourself needing another jumpstart.

    If a battery is bad, it won’t hold a chargeno matter how long you leave it hooked up to another car or charger.

    Push Start From Behind

    It is an old method, and you will need a helping hand to push the car from behind. Keep in mind that you have to set your ignition key a minimum on because while accelerating, it wont be good if the engine starts ultimately.

    Before pushing the car, release the brake and clutch as well. This little movement helps to start the engine, and your battery will be recharged.

    Jump Starting Your Battery

  • 1Park a functioning car so that it faces the car youre jumping. Jump starting a vehicle involves using the electrical system of another running vehicle to charge the battery in yours sufficiently to allow it to start and charge itself. Before parking the functioning car, make sure you locate the battery in both vehicles, as some vehicles batteries can be found in the trunk. Once you have located the batteries in both vehicles, pull the running vehicle up to yours close enough so allow your jumper cables to connect both batteries.XResearch source
  • If the battery is in the trunk of one of the vehicles, back it up to the other so the cables can reach.
  • Set the parking brake on both vehicles to ensure they dont move during the charging process.
  • 2Use jumper cables to connect the two batteries. Remember that once you connect the jumper cables to a battery, touching the positive and negative ends of the other side of the cables will produce sparks that may be dangerous. With both cars shut off, connect the jumper cable to the positive terminal of the dead battery and then to the positive of the good battery. Be sure not to allow the negative cables to dangle into the engine bay where they may touch metal that could serve as a ground to complete the circuit. Next, connect the negative cable to the negative terminal of the dead battery, followed by the negative cable on the appropriate terminal of the good one.XResearch source
