As a first step in fixing a drill battery that won’t charge, it’s important to test both the battery and the charger. Here are two methods to help you determine if they are functioning properly.

Using a Multimeter

One way to test the battery is by using a multimeter, which is a device that measures voltage, current, and resistance. To do this, set the multimeter to measure DC voltage and connect the red probe to the positive terminal of the battery and the black probe to the negative terminal. A healthy battery should have a voltage reading within the range specified by the manufacturer. If the reading is significantly lower, the battery may need to be replaced.

To test the charger, plug it into an electrical outlet and connect the multimeter probes to the positive and negative terminals of the charger. The voltage reading should match the output voltage specified by the manufacturer. If the reading is significantly lower, the charger may need to be replaced.

Assessing Charger Performance

Another way to test the charger is by assessing its performance while charging the battery. To do this, connect the charger to the battery and plug it into an electrical outlet. If the charger is functioning properly, it should charge the battery within the time frame specified by the manufacturer. If the battery doesn’t charge within the specified time, the charger may not be delivering enough power to the battery or may be defective.

It’s important to note that some chargers have a safety feature that prevents charging if the battery is too hot or too cold. If the battery temperature is outside the recommended range, the charger may not be able to charge the battery until it has reached the appropriate temperature.

By testing the battery and charger using a multimeter and assessing charger performance, you can determine if they are functioning properly and identify any issues that may need to be addressed to fix a drill battery that won’t charge.

If you’re dealing with a dead drill battery that won’t charge, don’t worry. There are a few simple steps you can take to fix the problem and get your drill back up and running.

Cleaning the Battery Terminals

The first thing to check when your drill battery won’t charge is the battery terminals. Over time, these terminals can become dirty or corroded, preventing the battery from making a solid connection with the charger. To clean the terminals, simply use a clean cloth or rag to wipe away any dirt or grime. For more stubborn corrosion, you can use a small wire brush or even a pencil eraser to gently scrub away the buildup.

Once the terminals are clean, make sure they are making a good connection with the charger. If necessary, you can gently bend the terminals to ensure a tight fit.

Boosting a Dead Battery

If the battery terminals are clean and the battery still won’t charge, it’s possible that the battery cells are dead. In this case, you can try boosting the battery to give it a little extra charge.

To do this, you’ll need a second, fully charged battery of the same type. Connect the positive terminal of the dead battery to the positive terminal of the charged battery, and then connect the negative terminal of the dead battery to the negative terminal of the charged battery. Let the batteries sit for a few minutes, and then try charging the dead battery again.

If these steps don’t work, it may be time to replace the battery. But by following these simple steps, you can often fix a dead drill battery and avoid the cost of buying a new one.

Reassembling and Testing the Drill

Now that the new battery is installed, I can reassemble my cordless drill. First, I will need to replace the chuck and drill bit if I removed them earlier. I will make sure to tighten the chuck properly to avoid any accidents while using the drill.

Once everything is in place, I will test the drill to make sure it is working properly. I will start by turning it on and checking the torque. If the torque is too low, I may need to adjust it using the torque adjustment ring.

Next, I will test the drill by using it on a piece of scrap wood. I will make sure that the drill bit is not slipping or wobbling and that the drill is able to make clean holes.

If everything checks out, I can now use my cordless drill with confidence knowing that the battery is fully charged and the drill is working properly.
