What Do The Lights on a DeWALT Charger Mean?
As with all cordless tool chargers, it can sometimes be a little difficult to decipher what a DeWALT charger is actually trying to tell you. All brands have their own system of symbols and lights to try and tell you how the battery is charging. So to make this simple I will be breaking down what all of the lights and symbols on a DeWALT charger mean, so with no further ado, let’s get into it.

Let’s start by having a good look at the charger. The one I am using for this example is a DCB115 XR Li-Ion charger. This charger works with multiple different batteries including 10.8V, 12V, 14.4V and 18V.
I love this, and it is not something I have seen with other power tools brands so far, although I haven’t used every single brand out there so maybe others do this too. What this means for you is that you don’t need a separate charger for your 18V batteries and 12V batteries if you get tools on both platforms.
This is where the actual information on the charger is displayed. This DeWALT battery charger is actually quite simple and only has two different lights. These two lights are used to display the charge status and also give an error if there is a problem.
Single Flashing Light
This means that the battery is charging correctly and is not yet fully charged. This is essentially the default “working” light. The charger is busy charging your tool battery and it has not yet been fully charged.
The larger left-hand section of the light bar will be flashing red. If the right-hand section is also lit up then this means there is a problem with the battery and/or charger.
Solid Single Red Light
When the flashing red light turns solid your battery has been fully charged. At this point, you can remove the battery from the charger and use it in your power tool.
Left Hand Flashing Right Solid
If both sections of the LED bar are lit up then you have a problem with your battery or charger. It is most likely overheating so simply remove it from the charger and let it cool before attempting to charge it again.
If you keep getting an error like this then the battery may well be damaged. You do not want to keep overheating the battery like this time and time again as lithium-ion battery fires can be very dangerous. If these battery set on fire they can explode and cause huge damage.
