As a DIY enthusiast, I know how frustrating it can be when your Craftsman power tool battery runs out of juice, and you don’t have the original charger on hand.
But don’t worry, there are several reliable and safe methods you can use to recharge your Craftsman battery without the manufacturer’s charger.
In this article, I’ll guide you through the step-by-step process and share essential safety tips to ensure a successful DIY battery charging experience.
Charging a Craftsman Battery Using a Car Battery
One of the easiest and most accessible options for charging a Craftsman battery without the original charger is to use your car battery. This method works well if both the car battery and the Craftsman battery are rated at 12 volts.
Here’s how to do it:
- Voltage Matching: Ensure that the car battery and the Craftsman battery have the same voltage rating, typically 12 volts. Using a mismatched voltage can damage the battery or pose a safety risk.
- Polarity Check: Carefully connect the positive terminal of the car battery to the positive terminal of the Craftsman battery, and the negative terminals to each other. Double-check the polarity to avoid short circuits or battery damage.
- Safety Precautions: Always exercise caution when working with car batteries, as they can produce explosive hydrogen gas. Ensure the area is well-ventilated and avoid sparks or flames. Additionally, remove any metal jewelry or accessories to prevent accidental short circuits.
- Charging Time: The charging time will depend on the Craftsman battery’s capacity and the car battery’s condition. Typically, it can take several hours to fully charge a Craftsman battery using this method.
Remember to monitor the charging process closely and disconnect the batteries immediately if you notice any unusual heat, smoke, or swelling.
Charging a Craftsman Battery with a Variable DC Voltage Source
Another reliable option for charging a Craftsman battery without the manufacturer’s charger is to use a variable DC voltage source, such as a bench power supply.
Here’s how to do it:
- Voltage Matching: Adjust the voltage output of the DC power source to match the voltage of your Craftsman battery, which is typically 18 or 20 volts.
- Polarity Connection: Connect the positive terminal of the DC power source to the positive terminal of the Craftsman battery, and the negative terminals to each other.
- Charging Monitoring: Keep a close eye on the charging process, ensuring the battery doesn’t overheat or experience any other issues. Adjust the voltage or current as needed to maintain a safe charging rate.
- Charging Time: The charging time will depend on the Craftsman battery’s capacity and the power output of the DC voltage source. A higher-powered source can charge the battery more quickly.
Using a variable DC voltage source is a versatile and reliable method for charging Craftsman batteries, as it allows you to precisely control the charging parameters to ensure a safe and effective charging process.
Repurposing a Laptop Charger to Charge a Craftsman Battery
If you have an old 18 or 20-volt laptop charger lying around, you can repurpose it to charge your Craftsman battery. This method is convenient and easy to set up.
Here’s how to do it:
- Voltage Matching: Ensure that the voltage output of the laptop charger matches the voltage of your Craftsman battery, which is typically 18 or 20 volts.
- Polarity Connection: Connect the positive terminal of the laptop charger to the positive terminal of the Craftsman battery, and the negative terminals to each other.
- Charging Monitoring: As with the other methods, keep a close eye on the charging process and monitor the battery for any signs of overheating or issues.
- Charging Time: The charging time will depend on the Craftsman battery’s capacity and the power output of the laptop charger. Larger-capacity batteries may take longer to charge fully.
Using a repurposed laptop charger is a simple and effective way to charge your Craftsman battery without the original charger, as long as the voltage ratings match.
Using a Universal Drill Battery Charger
Another option for charging a Craftsman battery without the manufacturer’s charger is to use a universal drill battery charger.
These chargers are designed to work with a variety of battery types and voltages, making them a versatile solution.
Here’s how to use a universal drill battery charger:
- Compatibility Check: Ensure that the universal charger is compatible with your Craftsman battery’s voltage and type. Most universal chargers can handle a range of voltages, but it’s always best to double-check.
- Charging Process: Follow the instructions provided with the universal drill battery charger. Typically, you’ll need to connect the battery to the charger and plug in the charger to a power source.
- Charging Monitoring: As with the other methods, keep a close eye on the charging process and watch for any signs of overheating or issues.
- Charging Time: The charging time will depend on the Craftsman battery’s capacity and the output of the universal charger. Larger-capacity batteries may take longer to reach a full charge.
Using a universal drill battery charger is a convenient and versatile option, as it allows you to charge a variety of battery types, including your Craftsman battery, without the original manufacturer’s charger.

Essential Safety Precautions When Charging a Craftsman Battery
When charging a Craftsman battery without the original charger, it’s crucial to follow proper safety precautions to prevent potential hazards. Here are the key steps to ensure a safe charging process:
- Voltage Matching: Ensure that the voltage of the charging source (e.g., car battery, laptop charger, or variable DC voltage source) matches the Craftsman battery’s voltage. Mismatched voltages can damage the battery or pose safety risks.
- Polarity Check: Always connect the positive terminal of the charging source to the positive terminal of the battery, and the negative terminals to each other. Incorrect polarity can lead to short circuits or battery damage.
- Insulation: Keep the battery terminals insulated to prevent accidental short circuits. Use electrical tape or other insulating materials if needed.
- Ventilation: Charge the battery in a well-ventilated area, as some batteries may release gases during charging that can be harmful if inhaled.
- Supervision: Monitor the charging process closely. If you notice any unusual heat, smoke, or swelling, disconnect the battery immediately.
- Fire Safety: Be prepared for fire risks by having a fire extinguisher nearby and avoiding charging near flammable materials.
- Temperature Considerations: Avoid extreme temperatures during charging, as high temperatures can degrade the battery, while charging in freezing conditions may reduce efficiency.
- Jewelry Removal: Take off any metal jewelry or accessories to prevent accidental short circuits.
By following these safety precautions, you can successfully and safely charge your Craftsman battery without the original charger, minimizing the risks of battery damage or personal injury.
