What You Need to Know About Charging Your Car Battery with another Car

With the pace we live in, you don’t want to find yourself stranded in a situation where your car won’t start due to a dead battery. Your schedule will be disrupted, no matter where you are at the grocery store, at the office, or even at home. The best way to take control of a situation is to infuse new life into your battery before you simply accept a loss of control. Considering the fact that modern cars have complicated electrical systems, jump leads should be connected in a specific order to prevent damage to other electrical components. You should read and follow the owner’s manuals of both vehicles before hooking them up.

Working Procedure of Car Battery Charging using another Car

A dead car battery is most commonly recharged using a car battery from another vehicle. When you do not have access to a car battery charger, you can use a car battery from another vehicle to ignite a dead battery. The battery will only be charged enough to ignite the car, and the alternator will take over the battery charging process. However, jump leads aren’t useful if the battery charging system or alternator is malfunctioning. By charging the dead battery with jump wires, power is transferred from the donor battery.

Proper Precautions while charging your car battery with another Car

The charging process of your battery is risky, and it can cause major injuries if done wrong. As long as you are curious enough to do it alone or there is some emergency on your part, you can take a few precautions to perform this process with ease & prevent any unfortunate incidents. It is always recommended to leave this task to professionals rather than do it yourself.

Battery Inspection

Identify any signs of damage to your battery by looking at its appearance & you should always wear gloves. Don’t attempt to recharge a battery if you notice any cracks or leaks of battery acid. Start by cleaning the terminals with a battery terminal brush if you see corrosion on the dead car battery but the rest of it looks okay. You can jump start your vehicle once you have cleaned off the battery and secured its cables.

Main Reason of Losing Charge of Car Battery

The inconvenience of a dead car battery is a hassle, but it can also be avoided. Knowing what causes a dead battery will help you prevent one.

01. Switch on the Music System Unnecessary

A working battery can also quickly be depleted by the audio system. You do not have to worry about draining your battery while listening to the radio on your commute to work since the alternator recharges it while the engine runs. It is essential that your battery be charged when the engine is running, as it cannot be recharged when stopped, allowing even the smallest electrical mishap to drain your battery completely.

02. Switch on the Headlights Unnecessary

After you park, you may forget to turn off your car’s headlights, which will discharge your battery. The first thing you should check if your car battery keeps draining is your lights. There are many new vehicles with headlights that turn off after a certain period of time. You may have to turn off your headlights if your car does not have this feature, or you may have to drain your battery before they stop working.

03. Bad Weather

A vehicle’s battery can suffer from problems caused by freezing winter weather and hot summer days. Batteries that are new tend to have higher resistance to extreme seasonal temperatures. It is possible for an older battery to suffer from breakdowns due to intense cold or heat, or even die altogether.

04. Old Battery

There is no such thing as a battery that lasts forever, including the one in your car. It depends on where you live and how you drive whether your vehicle’s battery will last up to five years. It is possible for your battery to last two to three years if you use it frequently and make short trips frequently. It may be time for a new car battery if yours quickly dies after a jumpstart.

05. Alternator Issue

The battery in your car is what powers your car when you start it. In order to stay charged, your battery relies on the alternator while the engine is running. You might not be able to start your car if your alternator is not working properly, even if it is just driving because it will not charge your battery properly.

06. Loose & Damage Battery Connections

Battery terminals, which are connected to the positive and negative terminals, can sometimes move loose over time. There is also a possibility of corrosion on these terminals. Your battery may not be able to transmit its power properly if your terminals become loose or corroded. It is possible that you could damage your vehicle’s electronic components or even stall while driving. By regularly cleaning your car’s battery terminals, you can help prevent corrosion related problems.

07. Too Many Short Trips

While the engine is running, your battery is recharged by the alternator. As a result, it takes a tremendous amount of power from the battery. When you make frequent pit stops, the alternator might not have sufficient time to properly charge your battery between pit stops, especially if your battery is old. The lifespan of your car battery can be reduced if you take too many short trips in the future.

08. Electronic Gadget Charging

Your car’s battery could be drained if you charge devices for too long while it is in ignition mode. Battery power provides power to things such as the alarm system, the clock, and the GPS even when the car is off. Your battery shouldn’t be negatively affected by these things. Rather than leaving a car on, it is possible to drain its battery by using interior lights, door lights, or by using bad relays.

The process can be completed following these simple steps if everything is fine.

  • You can make sure the working battery is facing you when you park the vehicle.
  • The positive and negative terminals of the batteries can be identified by opening the hood.
  • The positive cable on your jumper cables should be connected to the red positive terminal on the dead battery.
  • The positive cable should be connected to the positive terminal of the charged battery.
  • The jumper cable’s negative end should be connected to the negative terminal of the charged battery.
  • Your vehicle’s chassis should be connected to the other end of the negative jumper cable.
  • Make sure the battery is working, and let the car run for about two to three minutes.
  • You can keep both cars idling for 5 to 10 minutes after starting the vehicle with a dead battery.
