In the world of power tools, few brands are more trusted and respected than DeWalt. Their tools are known for their durability, efficiency, and innovation. However, like all good things, even DeWalt batteries have a lifespan. If you’re the proud owner of a DeWalt 9.6 battery that’s no longer holding its charge, there’s no need to toss it away. Rebuilding it can be a cost-effective and rewarding solution. In this article, we will guide you step-by-step on how to rebuild your DeWalt 9.6 battery, ensuring it performs like new once again.
Understanding DeWalt 9.6V Battery Packs
Before diving into the rebuilding process, it’s essential to understand what a DeWalt 9.6V battery consists of.
Components of the Battery
A typical DeWalt 9.6V battery pack includes:
- Cells: The heart of the battery, often consisting of Nickel-Cadmium (NiCd) or Nickel Metal Hydride (NiMH) technologies.
- Battery Case: The outer casing that protects the cells and provides structure.
- Connectors: Metal contacts that allow the battery to connect with DeWalt power tools.
Common Issues with DeWalt Batteries
Over time, batteries can develop various issues, such as:
- Decreased capacity, resulting in reduced run time.
- Inability to hold a charge, often due to aged cells.
- Physical damage or corrosion affecting connections.
Recognizing these issues could help you decide if your battery is a candidate for rebuilding.
Sourcing Materials for Rebuilding
To successfully rebuild your DeWalt 9.6V battery, you’ll need to gather the right materials and tools.
What You’ll Need
-
Replacement Cells: Depending on the original battery type, purchase compatible cells (NiCd or NiMH) with a voltage rating that matches the original.
-
Soldering Iron: A good-quality soldering iron is crucial for making electrical connections.
-
Wire Cutters and Strippers: For preparing and connecting wires.
-
Heat Shrink Tubing: For insulation of connections to prevent shorts.

The Rebuilding Process
Now that you have everything you need, let’s go through the rebuilding steps.
Step 1: Disassembling the Battery Pack
Before you begin, make sure the battery pack is completely discharged. Here’s how to safely disassemble it:
-
Remove the Outer Case: Use a screwdriver to remove the screws and carefully lift the top casing away. Take note of how everything is arranged to assist in reassembly.
-
Extract the Cells: Gently disconnect and remove the old battery cells from the case. Be cautious not to damage any connectors.
Step 2: Preparing the New Cells
Once the old cells are out, it’s time to prepare the new ones.
-
Check Compatibility: Ensure the new cells are the same size and voltage specification.
-
Connect the Cells: If the new cells have tabs, align them with the previous connections and solder them together, paying attention to polarity.
Step 3: Soldering Connections
Using a soldering iron, connect the cells following the configuration of the original battery pack.
-
Soldering Technique: Heat the metal tab and apply solder until it melts. Remove the soldering iron and let it cool completely.
-
Verify Connections: Use a multimeter to test connections before sealing. Ensure that the output voltage is 9.6V.
Step 4: Reassembling the Battery Pack
Now that the cells are connected correctly, it’s time to reassemble the battery.
-
Insert New Cells into the Case: Carefully place the newly assembled cells back into the battery case.
-
Seal the Battery Pack: Use the screws to secure the case back together, ensuring nothing is left loose or unconnected.
Step 5: Testing Your Rebuilt Battery
Once the battery is reassembled, it’s crucial to test it before putting it back in service.
-
Charge the Battery: Connect it to the charger and allow it to charge fully.
-
Check Performance: After charging, test the battery in your DeWalt tool. Monitor the run time to ensure it meets your expectations.
Maintenance Tips to Extend Battery Life
To maximize the lifespan of your rebuilt DeWalt 9.6 battery, consider the following maintenance tips:
Proper Charging Practices
- Avoid Overcharging: Once the battery is fully charged, unplug it from the charger to prevent damage.
- Use Compatible Chargers: Only use chargers specified for DeWalt batteries to prevent compatibility issues.
Regular Usage and Care
- Keep Cells Healthy: Regularly use the battery to prevent sulfation, which can lead to cell failure.
- Store Properly: Store your battery in a cool, dry place away from direct sunlight to prevent degradation.
