To charge a car battery, it is important to have a car battery charger. Sometimes a vehicle battery dies, but chargers are not within reach. It is therefore interesting to know how to recharge a car battery without a charger. Let’s learn how to do it?
Charge RC Car Battery Without Charger:
When you have jumper cables or if you can take some help from the citizen nearby, you can charge your RC battery without a charger. Ask a motorist for help to recharge a car battery without a charger. Sometimes your car's battery charged is flat in the middle of nowhere, with no town or vehicle nearby. It is then necessary to recharge the battery with the means on board.
When faced with this kind of scenario, knowing how to recharge a car battery without a charger is a useful skill. Instead of calling for a convenience store, you can enlist the help of another driver.
Consider finding a motorist willing to lend a hand. The technique consists of using the benefactor's car battery to recharge your vehicle's battery.
You must have jumper cables, more commonly called alligator clips. Some precautions should be taken to avoid accidents.
Ways to Charge a Car Battery Without a Charger:
Recharge a Car Battery Using the Cigarette Lighter:
There are some techniques for charging a car battery without a charger. You can use what is called a starter battery. It is about connecting the dead battery of your vehicle with that of another car.
Alternatively, if you can't find benefactors to help you charge a car battery without a charger with another battery, consider applying the second-start technique.
Also, remember that it is possible to recharge a car battery without a conventional charger. However, you must bring a battery booster. This little device plugs into the cigarette lighter. You must then wait 10 to 20 minutes.
After this period, your battery is sufficiently charged to allow your car to start again.
Check the Condition of a Car Battery:
It is possible to recharge a car battery without a charger by applying some simple techniques. But before betting on such a solution, you must know how to check the condition of your battery.
A car that does not start is not always the result of a dead battery. This problem can be caused by a malfunction in the engine, a failure of the alternator, a faulty fuel pump.
Be aware that in the majority of cases, the battery is the cause of the starting problem. For this reason, it is important to determine if your battery is dead.
To test your battery, you must have a multimeter. Then you have to follow a few steps:
- Set the multimeter in voltmeter mode to the 20-volt position
- Connect the black colored cable of this measuring tool to the negative terminal and the red cable to the positive terminal
- A voltage of 12.6v indicates that the battery is in perfect working order
- A voltage between 12 and 12.3 means the battery is discharged
- A voltage of 10.6 v means that the battery must be replaced, as it is at the end of its life
- If the displayed voltage exceeds 13V, the charging circuit must be checked since the battery is overloaded.
How to charge a car battery without a charger at home?
The first thing to do to charge a car battery without a charger with this method is to bring the two vehicles closer together. Remember to check the location of the batteries to better position the cars.
Make sure that the length of the cables connects the batteries of the two vehicles. Make sure that the cables are not stretched, as they can come loose during the process.
This technique requires the engine of the second vehicle to be started. Disconnect the battery terminals. These are the negative and positive terminals of each car's battery.
The next step is to connect the two batteries using jumper cables. The crocodile clips are to be connected to the terminals of the batteries of the automobiles involved in the process.
When connecting, compliance with the color codes is essential. Remember the black jumper cable on the negative terminals and the red cable on the positive terminals. This avoids confusing the battery terminals. Which is particularly dangerous.
When the connection is in order, it is time to start the vehicle. When your car purrs again, you can unplug the cables. For safety reasons, the red cable clamp must be removed first.
Finally, you must reconnect the terminals and properly close the hood of your vehicle. This technique is one of the most used to recharge a car battery without a charger.
Opt for the Second Start Method:
Not all batteries have the same lifespan. The latter depends on the type of battery. In addition, a maintenance-free battery has a shorter lifespan and sometimes discharges without warning.
When the charge level of a car battery is at its lowest, the vehicle has a starting problem. If possible, the battery in question should be recharged with an auto battery charger.
If the state of charge of your vehicle does not allow it to start, and you do not have a charger, there are techniques you can apply. The second start method is one of the best-known solutions.
With this technique, the vehicle must be driven at a speed of nearly 10 km / h. This allows a car to restart.
It is possible to adopt this technique solo. However, the car must be driven on a slope. Otherwise, unless you have Herculean strength, you must have several people push yourself.
The first step in this method is to depress the clutch and engage the second gear. The ignition must then be switched on to activate the electrical circuit.
Then you have to remove the handbrake while squeezing the clutch and let the vehicle roll by pushing or downhill. When the appropriate speed (10 km / h) is reached, the transmission will start.
All you have to do is take your foot off the clutch to start the car. This is a convenient method of recharging a car battery without a charger.
