Why Is My Black and Decker Charger Blinking a Red Light?

Black and Decker batteries come in variations of 20-volt, 40-volt, and 60-volt, with their most common being the 20V MAX Lithium Battery 3.0 Amp Hour.

This company is the gold standard when it comes to power tools and their accessories. Seldom do Black and Decker customers return to their store of purchase unhappy. That being said, their devices are not completely defect-free.

Here are the 5 most prominent issues attributed to a red-blinking Black and Decker charger:

  • Battery is overheating
  • Damaged battery
  • Charger is malfunctioning
  • Power source is inadequate
  • Glitch in the charging system

Fear not- we have some ideas to get the charge back in your battery and power tools back in your hands!

Issue #1: Battery Is Overheating

The most common reason your Black and Decker charger has a blinking red light is that the battery is too hot.

When this happens, you’ll see a long red flash, followed by a short red flash. Strangely enough, this can happen when your battery is too cold too. Overheating triggers your charger to go into “pack charging mode” in order to preserve the battery’s functionality.

This error code is both to let the user know there’s a problem and to prevent a fire from starting.

How to Solve This

When your battery gets too hot, you need to take it out of the charger and let it cool down.

Start by putting on some gloves (which you should do anytime you’re handling an electrically charged item). Unplug the charger and remove the battery from its station.

Give it at least 3 hours of downtime in order for the system to completely cool off. Keep in mind that Black and Decker batteries charge faster than other brands, so their risk for overheating is high.

Once 3 hours have passed, touch the battery with gloved hands to see if it has fully cooled down. If so, plug the charger back in and reinsert your battery. If the system is working properly, you’ll see a green blinking light in place of the red flashing.

Issue #2: Damaged Battery

The Black and Decker charger blinking red light could also mean your battery has sustained damage. If you notice that it’s swollen or enlarged, then do not attempt to charge it.

The pattern of blinking differs from an overheated battery in that a rapid flashing red light indicates a bad battery. This is your warning sign that it’s time to remove the battery from its charging station and dispose of it properly (once it has cooled off, of course).

How to Solve This

If your Black and Decker battery is damaged, you’ll need to purchase a replacement.

It’s not safe to continue attempting to charge this type of battery- the risk for further damage or an explosion is too high. If you’re not sure of where to dispose of it in order to prevent a fire hazard, take it to a Black and Decker recommended retailer for them to do it for you.

Whether you need a 20V, 40V, or 60V battery, you can purchase a new one from Amazon or a local hardware store!

Issue #3: Charger Is Malfunctioning

It’s also possible that your charger isn’t working properly, and that’s why it’s blinking red.

If your Black and Decker charger isn’t able to provide enough volts or power, it won’t be able to charge the battery adequately. Usually, if your power source is firing on all cylinders and your battery is in good working order- the charger is the thing to blame.

How to Solve This

If you suspect that your Black and Decker charger isn’t working properly, you have the option of taking its original store of purchase. If it was bought recently, you might be able to swap it out for a new one free of charge.

Otherwise, you can buy a replacement for $50. The power cord comes separately, so make sure to troubleshoot that piece independently to rule out the cable as the problem.

Issue #4: Power Source Is Inadequate

If your Black and Decker charger still isn’t working after you’ve tried the above steps, it could be your energy source.

A good way to gauge this is knowing that an average Black and Decker 20-volt battery takes around 30 minutes to charge. If your battery is taking excessively long to charge or isn’t holding any energy at all, check the outlet.

Additionally, did you have a power outage recently? Are they too many devices plugged into one outlet?

How to Solve This

If your power went out because of a storm, you’re going to have to wait for it to return; there’s not really much you can do at an individual level.

If you think the outlet is to blame, try moving your Black and Decker charger into a secluded area, away from interference. The more devices plugged into the same source, the more power has to be divided and shared.

Should you still not be able to receive adequate power for your charger, call your energy provider. They will be able to troubleshoot further!

Issue #5: Glitch in the Charging System

Occasionally, when you go to pop your low Black and Decker battery in the charging station- it blinks red for no reason at all.

Maybe the battery isn’t seated far enough down, or the prongs didn’t connect properly. Either way, there’s a little glitch in the system causing your charging station to blink red!

How to Solve This

In order to stop the flashing red light on your Black and Decker charger, take your battery out, and adjust the way you reinsert it.

When it’s seated, and correctly in place, the flashing light will turn green!

If the red light blinking doesn’t cease, there’s likely a bigger problem at hand.
