Battery Does Not Fit

Compatibility:

Voltage: Ensure the battery is 12V, matching the DCF901B's requirement. DeWalt offers 20V and 12V lines, and their batteries are not interchangeable.

Battery Type: DeWalt uses two main 12V battery types: XR (black and yellow) and Max (yellow and black). The DCF901B uses Max batteries. Check the label or markings on your battery to confirm compatibility.

Form Factor: There are different physical sizes and shapes within the Max line. While most Max batteries should fit, some specialized ones might not. Double-check the battery's physical dimensions against your impact wrench.

Troubleshooting:

Verify Compatibility: Ensure the battery meets the voltage, type, and form factor requirements mentioned above. Refer to DeWalt's website or user manual for specific compatible battery models.

Inspect Battery Connections: Look for any damage or debris hindering the connection between the battery and the tool. Clean the contacts if necessary.

Try Another Battery: If you have another compatible DeWalt Max battery, try using it to see if the issue persists. This can help isolate whether the problem is with the specific battery or the tool itself.

Check for Physical Obstructions: Ensure nothing is physically preventing the battery from sliding into place, such as debris or damage to the battery compartment or contacts.

If none of these steps resolve the issue:

Contact DeWalt Support: Their technical support team can assist you further in diagnosing the problem and suggesting solutions.

Consider Warranty: If your impact wrench or battery is under warranty, DeWalt might offer repair or replacement options.

Remember, using incompatible batteries can damage your tool or pose safety risks. Always adhere to DeWalt's recommendations and safety guidelines.

Incorrect Battery Size: Make sure the battery you're using is the right size and kind for your gadget. Different batteries have different dimensions and forms, thus using the incorrect one won't work properly.

Misalignment: Occasionally, misalignment may cause the battery to not fit. Verify that the battery is positioned and aligned correctly, as shown by the battery compartment of the device.

Obstructions: Look inside the battery compartment for anything that might be obstructing the battery's correct fit. Clear away any foreign objects or debris that might be obstructing the battery's entry.

Damaged Battery or Compartment: Look for any indications of damage to the battery as well as the battery compartment.

Incorrect Battery Type: Make sure the battery you're using for the DEWALT DCF901B is the right kind. DEWALT 20V MAX XR lithium-ion batteries work with this tool. It's likely that the battery will fit poorly if you use a different kind or size.

Debris or Damage: Inspect the tool's battery compartment for any debris, damage, or obstructions that might be keeping the battery from fitting correctly. If required, give the compartment a thorough cleaning, and look for any indications of damage that might require repairs.

Check to see if the battery you're trying to use is appropriate for the DEWALT DCF901B model. Although DEWALT 20V MAX XR batteries ought to work together
