The flashing red light means the charger is functioning correctly, and the Dewalt battery is charging.

Having issues with the Makita batteries, too? I have written a detailed post about what to do if your Makita battery is not charging.

Fix # 1: Faulted Wall Power Outlet

First of all, if your Dewalt battery is not holding a charge, check out your wall power outlet where you plug in your charger. Although it seems a minor issue, it can lead you to frustrating situations. Try the following steps:

  • You can also plug in other devices or chargers to the same outlet to check whether it’s working or not.
  • If the power outlet is not functioning well or is defective, plug in the charger adapter to another outlet.
  • If the other power outlet provides proper power to the charger, the charger indicates red blinking light.
  • Contrarily, after checking the other wall outlets, still the battery is not blinking red; there might be another problem.

Note: If the outlet is functioning well and still your Dewalt battery is not charging well, try the next fix.

Fix # 2: Malfunctioning of Battery or Charger

If the Dewalt battery is not holding charging properly, there might be a reason for the malfunctioning of the battery or charger. But the question is, how do you analyze which one is creating issues? To diagnose the real issue, follow these steps:

  • Disconnect the battery that is not holding the charge from the charger.
  • Try another Dewalt battery of the same volts according to the charger.
  • Make sure to fix the battery properly.
  • Check out, If the other battery starts charging and the red flashing light indicates on the charger.
  • If yes, the previous battery is faulty.
  • If this battery also doesn’t start charging, the charger is at fault.
  • Although it’s an occasional situation that both batteries are faulted yet it can be possible.
  • If the charger has some warrantee remains, contact the dealer.

Note: Maybe you are trying to charge the battery with the adapter plugged in, you need to remove the adapter as these batteries don’t hold a charge with the adapter plugged in (adapters are designed to accept inputs only).

Fix # 3: Clean the Corrosion and Dust

In the situation where the battery and charger both are suspicious of creating issues, this fix works like a wonder. After continuous usage or after lying idly without use, the dust, debris, and corrosion accumulated on the metal terminals of the battery and charger as well. To clean the contacts, try these steps:

  • You need to have white cloth, Q-tip, rubbing alcohol, and sandpaper.
  • Power off the charger and unplug it from the wall socket.
  • Disconnect the battery from the charger.
  • Clean the terminals of the battery and charger with a white cloth to remove extra dust and debris.
  • Soak the Q-tip in rubbing alcohol and clean the charger’s metal terminals.
  • The battery terminals are too tiny to clean easily, so be careful while handling them.
  • Try sandpaper in a folding form and rub the battery terminal gently.
  • After drying, seat the battery on the charger properly and replug the charger. Now check whether the red light blinks or not.

Warning: Attach the battery to the charger after drying out the terminals completely. The wet terminals can cause some serious problems.

Fix # 4: Store at the Appropriate Temperature

If the battery is in an idle situation, store it in a place with a moderate temperature. The temperature is not too hot or not too cold. Both adversities are fatal for the lifespan of the Dewalt battery. Also not charge the battery when it’s too cold, below 40 degrees, and too hot, above 105 degrees.

With these severe temperatures, your battery can’t hold a charge properly, or it might lose the runtime permanently.

Fix # 5: Revive the Sleeping Mode Slowly

Sometimes, when the battery remains stored idly for some days, or you use it after an indication of low battery, it goes to sleep mode. Therefore, you must put in some effort to awaken it from its deep slumber. It’s a bit time-taking process. It may not hold a charge as soon as you fix it on the charger.

To make it capable of holding a charge, give charging boosts of 2 to 3 minutes after small intervals. Gradually. It starts to hold a charge then you can charge it fully.

Pro Tip: don’t use the battery after it indicates the low battery. When you use it till its last breath, it becomes too flat to hold the charge quickly.

Fix # 6: Power Juice from Other Batteries

Despite applying all the fixes mentioned above, the Dewalt battery is still not holding a charge, which means it’s dead. So, here is a significantly exceptional trick to revive your battery. To get back your dead battery to life, you need to jump-start it. You can do it by following these effective steps:

  • You should have another fully charged Dewalt battery.
  • Both batteries should contain the same voltages.
  • Take two speaker wires/insulated wires.
  • Check and determine the positive and negative terminals of both batteries.
  • B+ indicates the positive terminal, and the negative terminal is indicated by B-.
  • Take a red wire and connect one end to the positive terminal of the dead battery and another end to the positive terminal of the fully charged battery.
  • Take a black wire and connect one end to the dead battery’s negative terminal and another end to the negative terminal of the fully charged battery.
  • Wait for a while, and the dead battery begins to suck the power juice from the charged battery.

Warning: Take good care to connect positively to positive and negative to negative. Otherwise, it can lead to severe damage to the battery.
