Tips for Charging a Cordless Drill Without a Charger
Before diving into the steps, it’s important to keep these key tips in mind for charging your cordless drill safely:
- Understand the Battery Voltage: The first step is to know the voltage of your drill’s battery. Most cordless drills run on 12V to 18V batteries. This will help you match the power output of your alternative charging method.
- Use Proper Connectors: Ensure that the connectors between your power source and the drill’s battery are secure and suitable for transferring power.
- Monitor the Battery While Charging: Since these methods are improvised, it’s essential to frequently check the temperature and status of the battery to avoid overheating or overcharging.
- Don’t Leave It Unattended: Unlike the standard charger, which may have automatic cut-off features, charging with alternative methods will require you to manually stop the process.
Use a hand drill
While it may seem unconventional, using a hand drill to generate power is one way to recharge a cordless drill battery. Here’s how you can do it:
Step 3: As you generate power, the battery will start charging. However, this method is time-consuming and will not provide a large amount of power, but it can help in emergencies.
Step 1: Connect the battery of the cordless drill to the output terminals of a hand-powered generator (like a hand crank drill).
Step 2: Start rotating the handle of the hand drill to create electrical energy.
Use a power drill
If you have a second power drill with a compatible battery, you can use it to transfer charge between batteries. Here’s how:
Step 3: Allow the batteries to transfer power for a short time. This method can give your cordless drill a quick boost, but it’s not a long-term solution.
Step 1: Remove the battery from the fully charged power drill.
Step 2: Use wires to connect the positive and negative terminals of the charged battery to the cordless drill’s battery.

Use a car battery
This is a powerful and efficient way to charge your cordless drill, but it also comes with higher risks. You’ll need to be very careful to prevent short circuits or damage to the battery. Follow these steps:
Step 3: Charge the drill battery for a few minutes. Be careful not to overcharge it, as car batteries are significantly more powerful.
Step 1: Identify the voltage of your cordless drill battery.
Step 2: Using a pair of jumper cables, connect the positive terminal of the car battery to the positive terminal of the drill battery and the negative to the negative.

Another way to charge a cordless drill without the charger
Another method you can use is to repurpose an old laptop charger or a universal adapter. If you have an adapter that can adjust to different voltage outputs, you can use it to charge your cordless drill battery. Set the adapter to the voltage that matches your drill, and connect the terminals to the battery. Monitor the charging closely, as this method can be risky if left unattended for too long.
How to prolong the battery life of your cordless drill?
Proper care and use of your cordless drill battery can prolong its life, ensuring it lasts longer between charges. Here are some tips:
Keep the drill in an excellent, dry location.
Heat and moisture can damage the battery over time. Always store your cordless drill in a cool, dry place to avoid temperature extremes and humidity.

Charge the drill after every use
Allowing the battery to deplete completely can shorten its lifespan. It’s a good idea to charge the battery after each use so that it’s ready for your next project and to maintain optimal performance.
Use the drill regularly.
Batteries tend to degrade faster when left unused for long periods. Even if you don’t need to use the drill, charge it occasionally and run it briefly to keep the battery in good condition.
The Benefits of Charging a Cordless Drill Without the Charger
Why would anyone choose to charge a cordless drill without the charger? There are several benefits to these alternative methods:
- Convenience in Emergencies: When your charger is lost or damaged, these methods can serve as emergency alternatives to keep your project going.
- Portability: When you’re on a job site without power outlets, using a car battery or other portable methods can save the day.
- Cost Savings: Instead of purchasing a new charger, you can use items you already have, such as a car battery or a second drill.
The Drawbacks of Charging a Cordless Drill Without the Charger
While charging a cordless drill without the proper charger has its advantages, there are notable drawbacks as well:
- Risk of Battery Damage: Without the proper charging controls, alternative methods can overcharge or damage the battery, leading to reduced lifespan or failure.
- Safety Hazards: Improvised charging methods can be dangerous if not done correctly, increasing the risk of fire, short circuits, or injury.
- Inconvenience: Some methods, like using a hand crank or transferring charge from another drill, can be slow and inefficient.
FAQS About How to Charge a Cordless Drill Without the Charger
Will a drill charge from another cordless drill?
Yes, you can charge one drill’s battery from another if the voltage is the same, and you have the proper wires or adapters to connect them. However, this method should only be used temporarily.
The battery in my drill doesn’t charge. What should I do?
If your drill battery is not charging, first check the battery terminals for dirt or corrosion. If the battery is still under warranty, consider getting it replaced. You may also want to test the charger or consider using an alternative charging method if the charger is faulty.
How do I clean the battery terminals?
Use a soft cloth or a cotton swab with a small amount of rubbing alcohol to clean the battery terminals. Ensure the drill is turned off, and the battery is disconnected before cleaning.
How long will it take to charge a cordless drill without the charger?
Charging times will vary depending on the method you use. Using a car battery or another drill will be faster, potentially taking 15-30 minutes. Hand-crank or other less powerful methods may take significantly longer.
Last Thoughts
Charging a cordless drill without the charger is possible with some ingenuity, but it’s not always the best or safest option. Whether using a car battery, a power drill, or a universal adapter, always be cautious and monitor the battery to avoid damage.
