You’ll need a battery charger or a home inverter if you want to charge your car’s battery with household electricity. In this article you will learn how to charge car battery with home electricity.
How to charge car battery with home electricity
Method – 1: Using an Inverter in Your Home
It will take less time to charge your automobile battery with your home inverter than it will using a charger. This approach should not be used on a regular basis, but it is a simple and quick method to utilize every now and again.
01. Connection Set Up
The connecting procedure is identical to that of the vehicle charger.
- The inverter should not be connected to the power source until all of the connections have been made.
- Connect the battery’s ground/negative connection to the inverter’s output port’s black wire.
- The positive wire must be connected to the output’s positive port’s red port.
02. Power Supply
The direct electricity from your house’s power outlets is used by home inverters.
- Before turning on the power supply, double-check the connections.
- Connect the inverter to the power outlet if everything seems good.
- If the wires are connected incorrectly, the battery may explode.
03. Putting It All Together
Inverters for the home have a large power supply. An inverter may charge the battery entirely in as little as 1.5 hours. Some may take up to three hours to complete.
It’s a simple way to charge quickly. If you don’t have enough time to wait for a trip overnight, the inverter technique is an excellent alternative.
Method – 2: Using a Car Battery Charger
You should get a high-quality car charger that is compatible with the battery type in your vehicle. Except for gel type battery cells, these chargers are compatible with almost all types of automobile batteries. Modern automobile battery chargers, on the other hand, are outfitted with cutting-edge technology. They’ll recharge the depleted batteries for you without any effort on your part.
01. Getting Ready to Charge Your Car’s Battery
First and foremost, you must put on your safety equipment. Although working with power supply units isn’t very tough, unforeseen problems might arise.
- Wear gloves that are resistant to electricity.
- Make sure you’re not standing on damp ground and that your hands and feet are clean and dry.
- Before connecting the cables, read the user instructions for the charger thoroughly.
02. Battery Remove
You must now remove the battery from your vehicle.
- Open the hood of the vehicle.
- First, disconnect the battery’s negative (black) wire.
- The red or positive wire should then be removed.
- Maintain a dry environment for the battery.
- To remove the dirt from the surface, wipe the battery with a damp cloth soaked in baking soda or just rub it with sandpaper.
- The accumulation of dirt on batteries has an effect on their power absorption.
03. Connecting the Charger and the Battery
It’s time to have the battery charged up again.
- Keep the car charger unplugged from your home’s power socket.
- Connect the black (negative/ground) wire to the charger’s black (negative/ground) port using a connector.
- The red (positive) cable should be connected to the red port.
- Never touch the wire ends with your bare hands; something might shorten the wires and cause them to conduct electricity.
- It’s also possible that a fire will be extinguished!
- Connect the charger to the power socket with caution now.
- The connection has been established!
04. Putting It All Together
The battery is now being charged. When the battery is fully charged, most modern automobile battery chargers feature indicators that sound an alert. Depending on the capacity of your battery and the voltage supplied by your power source, charging your automobile battery can take anywhere from 3 to 12 hours or more.
The majority of vehicle chargers will recharge your car’s battery in 12 hours or less. As a result, you may leave it to charge overnight. When the battery is fully charged, the charger will stop charging. So, you can sleep well at night and prepare your automobile for driving in the morning.
There are several charging options available.
As can be seen, there are a variety of methods for charging the battery. The first and most important step is to charge your phone properly. You must prepare yourself and your environment while using a good charger. Only then can you correctly connect the charger to the automobile battery.
Of course, you must link in the correct order. The usage of a home inverter is the second alternative. So it’s as simple as charging using a regular charger, but you should only do it if you don’t have one.
Charge the batter as soon as you have all of the essential equipment.
How Long Does It Take To Charge A Car Battery?
The time it takes to charge a normal 12V vehicle battery is affected by a number of factors.
These variables may be divided into two categories: internal and external.
Internal indicators:
- The health of the cells.
- The current retaining ability of the battery.
- The amperage of the battery.
External indicators:
- The power source you plan to utilize to recharge your car’s battery.
It is critical to understand that, even if you are using a high-capacity battery charger and the battery is in good condition, completely charging a car battery can take anywhere from 5 to 10 hours. A totally drained battery, on the other hand, would likely take longer to recharge than one that still has some charge.
This is one of the many reasons why car owners are encouraged to check their batteries on a regular basis, and why certain batteries take a long time to recharge.
You’ll need a battery charger or a domestic inverter if you want to charge your car’s battery with household energy. Also, keep in mind that the amount of time it takes to charge a battery is related to the charger’s amperage.
In layman’s terms, this means that a high amperage charger will charge the car’s battery faster in all conditions. You cannot, however, connect a charger to a battery, since this would not only destroy the cells in your battery, but can also, in many circumstances, create an explosion and damage beyond your comprehension (and I am not exaggerating).
Before you buy a battery charger, make sure it’s compatible by checking its rated capacity, because charging a car battery with a lower voltage rating than the charger might result in catastrophic cell damage and even an explosion.
However, if you only want to charge your car battery to the point where it can start your car, you may have to make some sacrifices, such as utilizing a household inverter as a battery charger.
Frequently asked questions for how to charge car battery with home electricity
How can I charge a car battery at home using electricity?
Connect the automobile battery to the inverter at home. The first thing you should do is double-check that the automobile battery is correctly connected to the power supply. You may accomplish so by connecting the battery’s negative terminal to the inverter’s black wire. Connect the positive portion to the red wire after that.
Is it possible to charge a car battery using a household outlet?
You’ll need a vehicle battery charger to charge your car battery from a wall socket. Although various automobile chargers function in somewhat different ways, the basic procedure is the same.
I don’t have a charger, therefore how can I charge my battery?
- Switch to a different device.
- Consider purchasing a portable power bank.
- It may be charged using a different battery.
- Make a charger using an old wire.
- The rubbing technique.
Is it possible to recharge a fully dead battery?
While the alternator in your vehicle can keep a good battery charged, it was never meant to fully recharge a dead car battery. If your battery is very low, connecting it to a jump starter or a specialist battery charger either before or after a jump start is your best option.
What is the best way for me to charge my battery at home?
Allow adequate space between the vehicles for the jumper cables to be attached. Place both vehicles in park or neutral and turn off the engines. Connect one of your jumper cables’ red clips to the positive terminal of the automobile that has a functional battery. Connect the second red clip to the positive terminal of the charged battery.
How long does it take to fully charge a car battery from an electrical outlet?
Because car batteries typically store 48 amps, a full charge with a 12 volt charger will take around 12 hours. It takes around 30 minutes to charge an electric car to 80% capacity.
How do you use power to charge a battery?
Place your battery charger near the battery, but do not connect it to a power outlet in your home at this time. Connect the black negative wire to the charger’s black negative connector. Connect the red positive wire to the red positive port on the battery charger.
Is it true that driving a car recharges the battery?
FALSE. Going for a drive, idling the motor, or taking a brief stop-start excursion will not entirely recharge your battery. In fact,’surface’ charging or chronic undercharging will reduce the battery’s capacity and diminish its life over time.
What is the maximum amount of time a car may be driven with a dead battery?
A disconnected vehicle battery can survive up to six months if properly stored out of the car in a secure location. It will require charging, just like any other automobile battery, but not as frequently as if it were connected. A decent rule of thumb is to charge the battery once every 12 weeks.
Is it possible for a car battery to be so dead that it will not jump start?
Yes, a car battery can die to the point that it can no longer be jump-started. To cut to the point, and before we get into the meat of the matter, a “dead” automobile battery is a sign of several things—and they nearly always happen at the same time.
Is it possible to charge a car battery overnight?
Even though using a high-quality charger eliminates the risk of overcharging, the battery should not be left attached to the charger for longer than 24 hours. Charging overnight usually results in a complete charge.
Is it possible to keep a car battery in your home?
If the battery is simply being stored in the room (not being charged or discharged) and is in a suitable protective case, it is absolutely safe. If the battery has a removable cap, caution should be exercised when charging owing to the release of hydrogen gas throughout the process.
Is it better to charge my battery at 2 amps or 10 amps?
It is preferable to charge the battery slowly. Slow charging rates differ based on the kind and capacity of the battery. When charging an automotive battery, however, a sluggish charge is defined as 10 amps or less, whereas a quick charge is defined as 20 amps or more.
How long does a 150ah battery take to charge?
Assuming a 150 Ah battery and 15 Amps of current, charging will take 10 hours if the battery receives 15 Amps. A solar panel normally draws 9 amps, so you’ll need at least two of them.
