- First, make sure your inverter is capable of producing enough power to charge your car battery. Check the specifications of both your inverter and battery to ensure compatibility.
- Connect the inverter to a power source, such as a generator or solar panel. Make sure it is properly grounded.
- Attach the positive cable from the inverter to the positive terminal on your car battery, and the negative cable to the negative terminal.
- Turn on the inverter and allow it to run until your car battery is fully charged. This may take several hours depending on the size of your battery and the output of your inverter.
- Monitor the charging process closely and disconnect the cables as soon as your battery reaches full capacity. Overcharging can damage your battery.

The Quick Answer:
An inverter converts DC power to AC power using electronic components like diodes, capacitors, and transistors. It allows you to use appliances during blackouts or when there’s no grid connection, making it ideal for camping or traveling. You can also charge a car battery with an inverter if it’s low on charge or dead, which can happen due to leaving your car lights on for too long or faulty electrical.
What is an Inverter and How Does it Work?
An inverter is an electronic device that converts DC power to AC power. It is used to provide electricity to appliances and devices that require AC power. The process of converting DC power to AC power involves the use of electronic components such as diodes, capacitors, and transistors.
The inverter works by taking the DC voltage supplied by a battery or other source and using electronic circuits to convert it into a sine wave alternating current (AC) voltage. This enables the inverter to provide a steady flow of electrical energy that can power a wide range of devices.
There are two types of inverters: pure sine wave inverters and modified sine wave inverters. Pure sine wave inverters produce a clean and stable waveform similar to the waveform provided by the utility company. Modified sine wave inverters, on the other hand, produce a stepped waveform that may not be suitable for some devices.
How Do Inverters Benefit You?
Inverters have several benefits, including:
- Allows you to use your appliances even when there’s no grid connection.
- Allows you to use your appliances during extended blackouts.
- Makes it possible for you to use your appliances while camping or traveling.
Why You Need to Charge a Car Battery with an Inverter
There are many reasons why you might need to charge your car battery with an inverter. For example, if your car battery is dead or low on charge, you can use an inverter to recharge it so that you can start your vehicle again. Alternatively, if you’re out camping or traveling in remote areas without access to electricity, an inverter can enable you to charge your car battery from any available DC source.
What Causes a Car Battery to Lose Charge?
There are several reasons why a car battery might lose its charge, including:
- Leaving your car lights on for an extended period
- Faulty electrical systems in the vehicle that drains the battery
- Aging of the battery itself
What Kind of Inverter Do You Need to Charge a Car Battery?
When selecting an inverter to charge your car battery, there are several factors you should consider. One important factor is the power rating of the inverter. The power rating should be high enough to provide sufficient current to charge your battery.

The type of inverter needed also depends on the voltage and amperage requirements of your car’s battery. Most modern cars use 12-volt batteries, so it’s essential to choose an inverter that can supply this voltage.
Another factor to consider when choosing an inverter is its efficiency. A more efficient inverter will convert more DC power into AC power, resulting in less energy loss during the conversion process.
What Size Inverter Do You Need?
To determine what size inverter you need, you’ll need to know two things: how much energy your battery requires and how long it will take for the battery to recharge fully. The formula for calculating this is:
(Size of Inverter) = (Energy Required by Battery) / (Time Required to Recharge)
For example, if your car’s battery requires 1000 watt-hours of energy to recharge and you want it recharged within four hours, you’ll need an inverter with a minimum rating of 250 watts.
Steps to Connect an Inverter to a Car Battery for Charging
To connect an inverter to your car battery for charging purposes, follow these simple steps:
- First, ensure that the inverter is switched off and disconnected from any power source.
- Next, connect the positive cable of the inverter to the positive terminal of your car battery.
- Connect the negative cable of the inverter to the negative terminal of your car battery.
- Switch on the inverter and plug it into a power source. The inverter should now start charging your car battery.
How Long Does it Take to Charge a Car Battery with an Inverter?
The time it takes to charge a car battery with an inverter depends on several factors, including the size of your battery, the capacity of your inverter, and the state of charge of your battery.
On average, it takes between 4 to 8 hours to fully charge a standard car battery using an inverter. However, this time can vary depending on how low your battery is and how powerful your inverter is.
Tips for Faster Charging
- Choose an efficient inverter with high power output
- Avoid using other appliances while charging your car’s battery
- If possible, avoid discharging your battery completely before recharging it
Safety Precautions When Charging a Car Battery with an Inverter
Charging a car battery with an inverter can be dangerous if not done correctly. Here are some safety precautions you should take when charging a car battery:
- Ensure that all cables are connected correctly before turning on the inverter.
- Avoid touching any exposed wires or terminals while the inverter is running.
- Keep the inverter away from any flammable materials.
- Ensure that the inverter is switched off when not in use to prevent accidental shocks or fires.

Can You Use an Inverter to Jump-Start a Dead Car Battery?
No, you cannot use an inverter to jump-start a dead car battery. Inverters are designed to convert DC power to AC power, and they do not have the necessary components to provide the high current required for jump-starting a car battery.
To jump-start a dead car battery, you will need a set of jumper cables and a second vehicle with a charged battery. Alternatively, you can use a portable jump-starter kit that comes equipped with its own battery and clamps.
In conclusion, charging a car battery with an inverter is a simple and efficient way to ensure your vehicle always has the power it needs. By following the steps outlined in this guide, you can safely and easily charge your car battery using an inverter.
Frequently Asked Questions about How to Charge Car Battery With Inverter
Can I wire a inverter directly to car battery?
The compact units include cables that can be attached directly to a battery. If you prefer to use an inverter that connects to your vehicle’s cigarette lighter, then you need to select one with a capacity of 450 watts or less. For inverters with a capacity of 500 watts or more, they have to be connected directly to a battery.
Will a 12v inverter drain my car battery?
Although the concept of an inverter draining a car battery is complicated, the basic principle is that the battery should not be drained when the vehicle is on, and particularly not when it is in motion. This rule of thumb applies to most situations.
Can a battery charge itself using an inverter?
It is impossible for current to both leave and enter a battery simultaneously. This is because the current can only flow in one direction at a time.
Can you charge batteries from an inverter?
Inverter/chargers cannot directly charge batteries using the DC current from a PV array. A charge controller is necessary to properly match the voltage from the PV array to the battery and regulate charging. However, there are some rare cases where this is not necessary.
How long will a 12V battery last with an inverter?
Based on our research, a 12V car battery connected to an inverter is likely to last between 10 and 17 hours. However, the exact duration will depend on the battery’s ampere-hour and the amount of power being used. There is a specific formula to calculate this, but it varies based on individual factors.
How many 12V batteries for 3000 watt inverter?
In order to power a 3000-watt inverter, you will need to purchase six battery banks with a 50Ah rating. However, if you opt for batteries with a 100Ah or 170Ah rating, you will only need three or two banks, respectively. It’s important to note that this information is only applicable for 12V systems.
