In this article, we are going to step through exactly how to find out if your DeWalt battery is bad and if you can bring it back to life! So keep reading; you are going to be a DeWalt battery expert in just a few minutes!
How Do I Know if my DeWalt Battery is Dead?
If your DeWalt battery is not working, of course, you will want to know if it is in fact the battery that is dead, or if the problem lies with the battery charger, or even worse, the power tool itself.
To find out if your DeWalt battery is dead, there are a few easy tricks you can try:
- Check the LED light on the battery charger: If the LED light is green, the charger is working properly, if it’s flashing red, it means it is malfunctioning.
- Use the same battery in a different wall charger: If you have two wall chargers, you can use the same battery in another charger; if it charges and works, it is clearly the wall charger that is dead, not your battery.
- Use a different battery in the same wall charger: If you do not have two wall chargers, but you do have two batteries, you can try to charge another battery. If it charges, unfortunately, the original battery is dead.
- Check the voltage of the battery charger to ensure it’s charging the battery fast enough: Even if the wall charger LED light is green and it seems to be charging at least one of your batteries, the problem may be that the charger isn’t functioning properly due to low voltage and therefore, older batteries are taking longer to charge and it seems as though it’s dead when it really isn’t.
If you have run through the above tests and both your batteries and chargers are functioning properly, if your power tools are not working with the fully charged batteries, it means the problem is actually with the machine and you will likely have to reach out to DeWalt to fix it .
Now that you know whether or not your battery is actually dead, you’ll probably want to know what you can do with a dead battery.
Can I Fix a Dead DeWalt Battery?
The good news is, a dead DeWalt battery is not the end of the world; however, in order to fix a dead DeWalt battery and bring it back to life, you will have to have electrical cords on hand.
If you follow various YouTube videos, the process itself is quite easy, but if you don’t have the proper equipment, you will have to go for another solution .
What To Do if Your DeWalt Battery is Dead?
You may or not know that DeWalt power tools, when purchased from an authorized retailer, come equipped with a three year warranty. However, batteries are considered normal wear parts due to regular usage and do not fall under the warranty’s coverage.
That means that if your battery is dead and you cannot fix it yourself, or do not have a friend who can, you are going to have to purchase a new DeWalt battery.
Luckily, hopefully, you now have all the information you need to know for sure if your DeWalt battery is dead before you go ahead and make an unnecessary purchase!
How Long Should a DeWalt Battery Last?
It’s important to understand how long a DeWalt battery should last in order to find out if your battery is simply dead due to old age or if there was a problem with the product.
DeWalt batteries should last about three years, depending on how often it’s used and how well it is cared for. It could last much longer if it’s kept in a safe and dry location and you only use it periodically.
If your DeWalt battery dies far before the three year mark, you could reach out to DeWalt. While it’s unlikely that they will send you a replacement for free, there’s no harm in trying!
The Bottom Line
You can find out if your DeWalt battery is dead by testing the battery itself in another wall charger, testing to see if the wall charger itself is the problem, or finding out if the power tool is the culprit.
If another battery works in either the charger or the tool, your battery is dead and you can either fix it yourself with electrical tools, or simply cave and purchase a new one.
