Car batteries are regularly charged by the vehicle’s electrical system, as most people know. There’s no reason to remove the battery for any other reason. Car batteries, on the other hand, are utilized for a variety of functions outside of the vehicle. The challenge now is to figure out how to charge the 12V battery without a charger. Follow these simple methods to easily recharge a 12V car battery.
Safety Factors
Consider the safety aspect before looking up “How to charge a 12V battery without a charger” on the internet. When working with a 12V car battery, you’re dealing with a lot of voltage and current flowing through the terminals.
Collect these items together, such as:
- Three, holiday lights
- Wire probes with clips
- Sturdy gloves
- Protective eyewear
All of these tools will assist you in recharging the car battery while keeping safety in mind. Because the illumination gives indicators for current control, the light bulbs or Christmas light are also safety tools.
How to charge a 12V battery without a charger
Method 1: To charge the battery, use a battery isolator
Battery isolators are a popular choice among regular campers and RV drivers. A battery isolator, once installed, allows you to charge a secondary battery using the alternator’s electrical output.
A battery isolator works by directing some of the alternator’s electricity to a second battery. It’s not the ideal option to charge a completely dead battery because it doesn’t deliver the same amount of electricity as a dedicated charger. This is because, while the vehicle is driving, the alternator must also charge the primary car battery and provide power to the vehicle’s various auxiliary systems.
It is, however, a good way to charge a 12V car battery that you can utilize in an RV or at a camping as a power source. They can also be used in conjunction with solar panels to charge a secondary battery.
Method 2: Use A Portable Car Jump Starter To Charge The Battery
Although the jump starter isn’t used to charge the battery, it is utilized to start the process. The alternator will take over the operation to charge the battery once the engine is started.
Here are some pointers on how to use a jump starter.
- Before you begin, double-check the battery’s condition. Using a jump starter to start the engine if the battery is old or dead is pointless. Before you begin, test the batteries with a multimeter to ensure that it is in good working order.
- All auxiliary electrical systems in the vehicle, including lighting, music equipment, phone chargers, and air conditioning, should be turned off or disconnected. These are a drain on the battery and may prevent the engine from starting when the jump start is used.
- Before connecting the jump starter, check to see if the existing battery terminals are corrosion-free and clean.
- To avoid damaging the vehicle’s electronics, always connect the jump starter with the ignition switched off.
Method 3: Put The Battery Into Another Vehicle To Charge
If you have access to another car with a battery that is identical to the one you’re trying to charge, you might be able to utilize that vehicle to charge your dead battery.
This isn’t the most efficient technique to charge a battery, but it can work in some cases, particularly on older vehicles with simpler circuitry. It’s also a wonderful technique to recharge a 12V car battery if you’re going camping or in an RV.
There are a few things you should verify before replacing the batteries.
- Check to see if the dead battery is the same form and size as the one in the other vehicle.
- You should also check that the dead battery has a similar mAh rating to the one in the donor vehicle.
- Finally, ensure the donor car doesn’t require the battery to be registered with the ECU before it can properly charge it.
If all of the aforementioned parameters are met, you can install the dead battery in the donor vehicle. Make sure the car’s engine is turned off and any auxiliary electrics are turned off.
If the battery is completely dead, you’ll need to jump start the vehicle so that the alternator can begin charging the dead battery.
The best technique to charge a dead battery once the battery is installed and the engine is running is to take the car on a lengthy drive. This ensures that the battery is charged gradually and completely.
Method 4 : Use A Home UPS Inverter
To convert DC battery power to AC power, a UPS inverter can be employed. They’re typically placed to allow a 12V battery source, such as an inverter battery, to be used as a backup power supply in a home or company.
A home inverter battery is a battery that can be used to power devices around your house for a limited time, such as during a power outage.
A tall tubular inverter battery is the most common type of inverter battery. They’re used in homes, RVs, and campgrounds as backup power sources.
If you have access to a UPS inverter, you can use it to charge a 12V car battery on occasion. Before you begin, read the inverter’s manual to ensure that it can securely charge a 12V car battery.
Most inverters have built-in safety measures that monitor the battery voltage and prevent overcharging and overheating, but you should always double-check before charging.
Method 5: Use a solar panel
A solar battery charger or solar panel is another frequent way to charge an automobile battery.
If you understand the fundamentals of voltage and amps, a solar charger is easy to create and use. It’s not the most efficient way to charge a 12V car battery, especially if the battery is fully dead.
Charging a completely dead battery can take up to 8 hours. It depends on the solar panel capacity and battery size.
Before using a solar panel to charge a 12V car battery, it’s vital that you know what you’re doing. You can’t just leave the solar panels connected to the batteries.
To charge a 12V car battery, there are several ways to connect a single solar panel, but I recommend at the absolute least using a solar charge controller.
An effective solar charge controller can prevent overcharging and restrict reverse current.
The second option to use a solar panel is to use a specialised solar panel battery charger. A good quality solar panel charger comes with all you require to safely charge a 12V car battery. It can protect the battery from overcharging while also extending its life by preventing it from becoming completely depleted.
It’s crucial to consider the battery size while selecting a solar charger. It will help to select the exact solar panel, as well as the time required to charge the battery.
For instance, a 100W solar panel charger can deliver approximately 6 Amps. It would take approximately 8 to 10 hours to charge a 12V car battery from dead to fully charged.
Method 6: Charge by using jump leads and a donor vehicle
Jumper cables and a donor vehicle are the most typical methods for charging a dead automotive battery.
If you don’t have access to a car charger, the easiest and safest way to start a car with a dead battery is to use jump leads.
It’s vital to understand that jump leads will only charge the battery enough to start the car; after that, the alternator will take over. If you have a problem with your car’s battery charging system and the battery won’t charge, using jump leads won’t help you much.
Before connecting the jump leads, make sure to read the owner’s manuals for both vehicles. Due to the complexity of modern vehicles’ electrical systems, jump leads must be attached in a certain order to avoid causing harm.
Here are a few tips on how to jump start a car.
Tip 1: Check that the battery connections on the dead battery are clean and free of dirt and corrosion before connecting the jump leads. Use a wire brush to clean them, or a baking soda solution if they’re particularly bad.
Tip 2: Make sure the jump leads are heavy enough to start the dead battery. To guarantee that they can safely carry the current and do not melt, they should be no more than 6 gauge (ideally 4 gauge).
Tip 3: Allow at least 10 minutes for the donor car’s engine to warm up before attempting to start the vehicle with the dead battery. This will ensure that the dead battery has enough charge to keep the engine going after you start it.
Car Battery Care Tips
It is less likely that you will become stranded if you maintain your car battery. Here are some battery-related recommendations.
- To keep the charge full, use a battery maintainer.
- Carry a backup battery charger in case the main one dies.
- Clean the corrosion on a regular basis.
- Examine the battery for signs of impending failure.
- Longer excursions will allow the alternator to recharge the battery.
- When the car is turned off or idling, don’t turn on the lights or accessories.
