Jump-starting a car battery can be daunting, especially if you're unfamiliar with the process.
However, with the right tools and knowledge, anyone can do it. If you're using a Milwaukee M18V battery, the process is slightly different from a traditional car battery.
In this article, we'll walk you through the steps to jump-start a car with a Milwaukee battery.
Before we get started, it's important to note that jump-starting a car can be dangerous if not done correctly.
Always wear gloves and eye protection, and make sure the battery is not leaking or damaged.
It's best to call a professional if you're unsure about anything. With that said, let's get started.
Can You Really Jump Start A Car With A Milwaukee Battery?
So, you're stranded in a parking lot with a dead car battery and no one to help you.
You remember hearing a rumor that you could jump-start a car with a Milwaukee power tool battery. But can you really?
According to some YouTube videos and Reddit posts, it is possible to jump-start a car with a Milwaukee battery.
However, it's important to note that not all batteries are created equal. Milwaukee batteries are known for their high-quality and long-lasting power.
They are designed to provide reliable power to Milwaukee power tools, but they can also be used to jump-start a car in an emergency situation.
Before attempting to jump-start your car with a Milwaukee battery, it's important to make sure that the power tool battery is fully charged.
A half-charged battery might not give you enough power to jump-start your car.
⚠️ Disclaimer: Jump-starting a car with a power tool battery should only be done in emergency situations, not for a long-term fix or replacement.

Pre-Jump Start Safety Precautions
Before attempting to jump-start a car with a Milwaukee battery, it's important to take some safety precautions to avoid any accidents or injuries.
Here are some tips to follow:
- Make sure that both vehicles are turned off and the keys are removed from the ignition before connecting the cables.
- Wear protective gear such as gloves and safety glasses to protect yourself from any sparks or battery acid.
- Remove any metal jewelry, such as bracelets or watches that could accidentally touch the battery terminals and cause a short circuit.
- Check the battery for any cracks, leaks, or other damage. If the battery is damaged, do not attempt to jump-start it.
- Position both vehicles so that they are not touching each other and the batteries are as far apart as possible. This will prevent any accidental contact.
- Always connect the jumper cables in the correct order: positive to positive, negative to negative.
- Avoid smoking or using any open flames near the battery. Battery acid is flammable and can cause an explosion.
Making Sure the Battery Voltage Matches: How Important is it?
If the voltages do not match, it can cause damage to both batteries and potentially harm the person attempting the jump start.
To check the voltage of the Milwaukee battery, you can use a digital multimeter.
Set the multimeter to the DC voltage setting and connect the red lead to the battery's positive terminal and the black lead to the negative terminal.
The voltage reading should be around 18 volts for a fully charged battery.
Once you have confirmed that the voltage of the Milwaukee battery matches that of the dead battery, you can proceed with the jump-start process.
It's important to note that using a Milwaukee battery with a lower voltage than the dead car battery can overwork and damage it.
On the other hand, attempting to jump-start a car with a Milwaukee battery that has a higher voltage can cause damage to the electrical system of the car.
Step-by-Step Guide: Jump Starting Your Car with Milwaukee Batter
With precautions in place and the right voltages confirmed, let's explore how to jump-start your car using a Milwaukee battery.
Step 1: Prepare Your Equipment
Ensure you have two wires to transfer power from the Milwaukee M18 power tool battery to your car.
Again, your power tool battery must be fully charged to ensure a successful jump start.
Step 2: Identify Battery Terminals
Before making any connections, you must identify your power tool battery's positive and negative terminals.
Correctly determining these terminals is crucial to prevent any electrical mishaps.
Step 3: Setting up the Connections
Typically, Milwaukee M18 batteries feature slots instead of terminals.
Use wire ends designed for these slots to connect while correctly identifying the positive and negative slots.
Step 4: Connect to the Car
Now, carefully attach the other end of the positive wire (from the power tool battery) to the car's positive terminal.
Similarly, attach the other end of the negative wire to the car's negative terminal.
Step 5: Starting the Car
With the power tool battery connected, turn the ignition. Your car should power up using the power tool battery's energy.
Again, this method is strictly for emergency purposes. It's not intended to run your car on a power tool battery continuously.
For those who might wonder if the car's main battery should be removed or left connected, it's advisable to leave it connected.
Doing so ensures that your car won’t switch off once you disconnect the power tool battery, maintaining a closed circuit.
For a detailed visual walkthrough of these steps, refer to the video below showcasing these procedures.
In the demonstration, the Milwaukee M18 battery, rated at four amps, successfully jump-started a small engine.
If you're working with bigger engines or vehicles, you might want to consider a power tool battery with a higher amperage.
Why Isn’t My Car Starting Even After Jumping?
Sometimes, even after jump-starting your car, it may still refuse to start. Here are some possible reasons why your car isn't starting even after jumping:
Corroded Battery Terminals
Corroded battery terminals can hinder your vehicle from starting, even if you've managed a successful jump-start.
Corrosion can build up on the battery terminals over time, preventing the battery from delivering power to the engine.
You can clean the battery terminals with a wire brush or a mixture of baking soda and water.
If your car starts but then dies shortly after, or if the battery warning light is illuminated on your dashboard, it could be a sign of a faulty alternator.
The alternator is responsible for charging the battery when the engine is running.
If it's not working properly, it won't be able to recharge the battery, and your car will eventually stop running.
If your car's starter is failing, it may not be able to turn the engine over, even with a jump start.
You can try tapping the starter with a hammer or a wrench to see if that helps it to start. If that doesn't work, you may need to replace the starter.
Is It Safe to Immediately Drive After Jump Starting?
Driving your car for at least 30 minutes after the jump starts is generally recommended.
Doing so will ensure that your car battery has enough power to start the engine the next time you need to use it.
However, for a more effective charge, it's advisable to drive the car rather than leave it in an idle state.
This active charging can provide more consistent results in revitalizing your battery.
Can Jump Starting Damage My Vehicle or the Milwaukee Battery?
The answer is yes. Jump starting can damage both your vehicle and the battery if not done correctly.
When jump-starting a car, the high amount of current that is required can overheat and damage the cells in the battery.
This can reduce the battery's lifespan and might lead to its early failure.
Moreover, if the jump-starting process is done incorrectly, it can damage your vehicle's electrical system, including the alternator, starter motor, and other components.
Be sure to follow the correct jump-starting procedure as detailed above to avoid damaging your vehicle or the Milwaukee battery.

Jump-starting a car with a Milwaukee battery is a convenient and easy solution for when you find yourself with a dead battery.
With the right tools and knowledge, you can safely and effectively jump-start your car and get back on the road in no time.
Remember to always prioritize safety. Wear protective gear and ensure that both batteries are of similar voltage before connecting the cables.
Follow the steps carefully and double-check your connections before starting the car.
