Why is my drill not charging

Common reasons your drill may not be charging

Your drill may not be charging due to an overcharged battery being damaged. When you leave the drill’s charger plugged in, it may get damaged. If the battery pack is not properly inserted, the drill will not charge. 

Insert the drill charger, otherwise, there will not be magic on the drill. When the outside temperature is too cool or higher, a battery will not work. When temperatures are high, the battery is overheated, and it stops working.

Check the battery to see if it is not dead. A dead battery does not charge. Bad environment conditions such as more humidity, ice, more sunlight, and flames near the charging will affect the process and efficiency of the charging.

Do not crush, drop, roll or damage the batteries if there is a problem because damaged batteries will not charge. 

Using a faulty charger means that the battery will not charge. The battery might also not be fully locking into the charger; thus, the two’s contact is lost, meaning no power transmission.

Other reasons include:

  1. The drill battery may not be inserted properly
  2. The drill charger may not be plugged in
  3. The outside temperature may be too cool or high
  4. The battery may be dead
  5. Bad environment conditions such as more humidity, ice, more sunlight, and flames near the charging will affect the process and efficiency of the charging.
  6. The battery might also not be fully locking into the charger; thus, the two’s contact is lost, meaning no power transmission.
  7. Outside temperature may be too cool or high causing the battery to stop working.

How do you fix a drill battery that won’t charge?

Ensure that all parts are in good condition and that the charger you are using is recommended. Make sure the battery is working so that you follow the steps below.

  1. Cut off the end of the Ac adapter. Use an old adapter that you do not need anymore.
  2. Separate and remove the cover of each one up to about an inch long. The black wire is negative, while the striped or solid white wire is positive.
  3. Unscrew the cover holding the batteries together.
  4. Pry the plastic cover off to get at the screw underneath.
  5. Pull the top cover off the battery.
  6. Remove the two plastic side pieces, then lift the battery pack out.
  7. Set the multimeter to read volts for an accurate reading.
  8. Attach the red clip to the +ve terminal and the black clip to the -ve terminal. Read the voltage displayed on the multimeter.
  9. Plug your Ac adapter into a socket and, using the wires, boost the battery. Attach the black wire to the negative terminal and the white wire to the positive terminal for about a minute.
  10. Test your voltage on your battery pack and ensure that it is higher than before boosting.
  11. Reassemble the plastic covers on the battery pack and set the battery on the charger to see if it will charge. If you get a red flashing light, and the battery will not charge, repeat the procedure.
  12. Repeat the boosting and testing until the battery is recognized by the charger. Expect a green light.

How do you bring a battery back to life?

Seal the battery in an airtight bag and put it in the freezer for about 24 hours. Ensure no moisture in the bag could get the battery wet. When you take it out of the freezer, let it thaw for up to eight hours to restore it to room temperature.

How do you revive a lithium-ion drill battery?

  1. Cut the end of an old mobile phone charger that is not in use.
  2. Separate the two wires and remove their cable covers. 
  3. Remove the screws of the battery pack.
  4. Open the battery case.
  5. Remove the two plastic pieces on the sides. 
  6. Pull out the battery pack.
  7. Check the volts level with the help of a multimeter. 
  8. To check the voltage levels, connect the red probe to the red terminal (positive ends) and the black probe to the black terminal and check the reading on the multimeter.
  9. Take the ac adapter/the old charger that you used to create a booster, and touch the black wire to the negative terminal and the white or striped wire to the positive terminal. Keep doing this on and off for about a minute.
  10. Check the voltage of the battery with the help of the multimeter. The boosting process would have raised the voltage levels.
  11. Put the battery pack inside the battery case and secure the plastic and the screws.
  12. Connect the battery to the charger to check if it is getting charged now.

Can you reset a Milwaukee battery?

Yes, you can reset a Milwaukee battery. Remove the battery pack from the tool and place it on the charger to reset it. Shut down the battery pack by placing it on the charger to be reset, press the fuel gauge button, and if the bottom gauge flashes once, reset the battery by placing it on its charger.

Why is my power drill not working?

There might be power loss and intermittent operation or failure to run at all. 

Can battery Chargers be repaired?

Yes, they can. If you find that your charger refuses to charge your battery, repair the fuse in the mains plug and the fuse on the battery charger. It is highly likely to be one of the fuses that have blown.

How do I know if my drill battery or charger is bad?

When the battery charger is giving you a negative reading. A negative reading will indicate a bad battery charger, and you should replace it.

How do you test a drill battery charger?

  1. Determine the voltage rating of the battery charger. The voltage will be marked on the charger, drill, or battery.
  2. Set the multimeter to the voltage setting that matches or exceeds the battery voltage rating. 
  3. Plug the charger into an electrical outlet. 
  4. Read the meter. If the meter does not produce a reading, the charger is faulty.

How do you check to see if a battery charger is working?

  1. Plugin your charger into an electrical outlet. 
  2. Turn on your voltmeter unit. 
  3. Take a battery or battery pack that’s compatible with your battery charger.
  4. Check the readout on the voltmeter and see where the pointer is indicating.
  5. Check the battery charger to see how much power it’s giving off.

Do cordless drill batteries go bad?

They do but after a long time. Cordless tool batteries last for several years, and with proper care and storage, you can extend battery life and your investment.

How do I know if my DeWalt battery charger is working?

Dewalt charger red light means that the battery is charging. Don’t unplug the charger until the battery finishes charging.

How do I know if my Black and Decker battery charger is working?

There is a charging light on the black + decker battery charger. This light changes color or goes out once the battery is charged. If the light doesn’t go out or change its color, meaning the charger is not working.

How do I know if my drill is charging?

Check on the reading to see if it is positive. 

How long does it take to charge the drill battery?

Charging time depends on charger capacity, battery capacity, and charging technology. Charging a cordless drill battery takes 30 mins to 5 hours to charge. An ultrafast charger will take 11 mins. If you use a fast charger, it will take an average of 1 hour.

How does a drill battery charger work?

It works using electricity from the mains and filling up a discharged battery with power.

How do you test a drill battery cell?

A bad cell gives you a false voltage reading. Batteries with open cells may read fully charged in idle, but they fail under a load test every time.

Drill battery dies quickly.

The battery may no longer hold a charge. Use a new battery. Another problem can be because of the battery charger. The charger may have a connection problem, and thus the battery is not being charged.
