Charging a car battery without a charger can be done using various alternative methods. Keep in mind that these methods might not be as effective or safe as using a proper charger, and they should be used as temporary solutions. In case of a completely dead or damaged battery, it’s recommended to consult a professional or replace the battery. Here are a few methods of how to charge a car battery without a charger
How to Charge:
Bellow are the few Techniques to Charge a Car Battery Without a Charger:
1. Jump-Starting from Another Vehicle:
- Park the two vehicles close enough so the jumper cables can reach both batteries.
- Engage the parking brakes after turn off both vehicles.
- Connect positive + or red cable to positive terminal of the dead battery that need to charge.
- Connect other end of the positive cable to the positive terminal of the working battery.
- Connect negative – or black cable to the negative terminal of the working battery.
- Connect other end of the negative cable to a metal surface on the dead vehicle which is away from the battery. This acts as a grounding point.
- Start the working vehicle and let it run for a few minutes to charge dead battery.
- Attempt to start the dead vehicle. If it starts, let it run for a while to charge the battery.
2. Using a Battery Charger from a Store:
If you don’t have a battery charger, you might be able to borrow or rent one from an auto parts store, hardware store, or even a friend. Battery chargers are designed to safely charge car batteries and can be a better option than some alternative methods.
3. Using a Trickle Charger:
Trickle chargers are specifically designed to provide a slow, constant charge to a battery. Open the car’s hood carefully. Now locate the battery. Identify the positive (+) or red and negative (-) or black/blue terminals on the battery. Attach the positive (red) clamp from the trickle charger to the positive terminal (+) or red terminal of the battery. Attach the negative or black clamp to the negative terminal (-) or black terminal of the battery. You might be able to find a trickle charger at an auto parts store or online.
4. Solar Chargers:
Solar chargers can also be used to charge a car battery. These devices use sunlight to generate a small amount of charging power. They are most effective in sunny conditions and are typically used to maintain battery charge rather than fully charge a dead battery.
5. Push or Bump Start (Manual Transmission Only):
If your car has a manual transmission, you might be able to start it by pushing or bumping it. This method requires some space and assistance from friends. You essentially start the car by building momentum and engaging the clutch quickly. However, this method won’t actually charge the battery; it’s only a way to start the car if the engine can run on its own.
If you are still finding method on How to Charge a Car Battery Without a Charger then you follow this steps:
With the Help of Wind Generator:
By using wind-power generator you can charge a car battery without a charger. If the wind generator create same voltage then you can connect that voltage with your car battery directly with the help of a diode.

By the Help of Hydro Generator:
Hydro turbine generator can charge a car battery without a charger. If the hydro generator create same voltage to the car battery voltage then you can connect that voltage with your car battery directly with the help of a diode.
By Using DC Generator:
DC generator can easily charge car battery without charger. First need to adjust car battery voltage to the output voltage of DC generator. Generator output voltage need to be same with car battery voltage or you can increase generator voltage to 1v or 2v or similar. Start the generator then connect generator positive and negative terminal to the battery positive and negative terminal.
By using UPS battery:
Turn off the UPS and disconnect it from any power source. This is crucial to avoid electrical shocks. Attach the jumper cables or battery charging cables to the appropriate terminals on the car battery. Connect the positive or red cable to the positive terminal (+) of the battery. Then the negative or black/blue cable to the negative terminal (-) of the battery. Use the appropriate cables to connect the UPS power inverter to the car battery. Connect positive cable to positive and negative cable to negative terminal of battery. Keep an eye on the car battery voltage and the charging process. You may need a voltmeter to measure the battery’s voltage periodically.
Charging a car battery using an inverter can be slower than using a dedicated battery charger. The time required for a full charge will depend on factors like the battery’s current charge level and the capacity of the inverter.
Remember that these methods are temporary solutions and may not fully charge a deeply discharged battery. Additionally, improper handling of batteries can be dangerous. If you’re not familiar with these procedures or are unsure about your battery’s condition, it’s best to seek assistance from a professional mechanic.
