Why Is the Battery on Dewalt DC970 Not Charging?

The Dewalt DC970 is an excellent tool for any handyman, but if you notice that your battery is not charging, it’s time to do some troubleshooting. This blog post will discuss and cover how to tell if there’s a problem with the battery, what could potentially cause the issue and more.

What is a Dewalt DC970 battery?

Dewalt is a well-known brand when it comes to power tools. They are known for high quality and performance. One of their most popular products is the Dewalt DC970. It’s a power drill that can be used for many different things around the house, from hanging pictures to assembling furniture and so on. The DC970 is a cordless drill that allows you to work on projects without being restricted by the availability of an electrical outlet.

This Dewalt DC970 is powered by an 18/20-volt NiCd rechargeable battery. This type of battery can go through a number of charge and discharge cycles without losing its capacity. The fully charged Dewalt DC970 battery has the ability to work on the drill that can last for hours until you need to charge it again, but this will depend on how often you use your power tool.

Why is the battery on Dewalt DC970 not charging?

We all know that batteries are essential when it comes to drills and power tools. Sooner or later, these batteries will lose their energy and will need a recharge. It can be pretty frustrating if you find out that your battery for a drill doesn’t charge or if it charges very slowly.

There are factors to consider or to look at why this might happen, and very few of these factors are as follows:

The charger is disconnected or is not plugged in properly: Be sure that your Dewalt DC970 battery charger is plugged in and that the part which goes into the drill is positioned accordingly. Plug the battery charger into an electrical outlet and turn it on. If you see lights blinking red, then that means that the device is currently charging.

Blown or defective fuse: Examine if there is a blown fuse and replace it. There is a fuse for the Dewalt DC970 at the bottom of the battery charger.

Old battery: It is possible that the battery of your drill has reached its end. Old batteries don’t charge as they used to and therefore, you should consider buying a new battery. If this is the issue, then this will be an easy fix.

Bad battery charger: If you find out that the battery is still not charging, then you might need to replace your old battery charger. You can contact Dewalt for help with getting it replaced.

If the issue continues, then there is a possibility that you have a faulty battery. However, this does not mean that your drill will be useless since it might just need some adjustments. Purchase the same battery model for optimum performance.

How do you know when your battery needs charging?

This could depend on a few factors, such as your battery, the model of the tool, and the voltage of your battery. If you use tools with a lot of power (higher voltage), such as a drill or circular saw, you may not notice that your battery is running low until it turns off in the middle of what you’re doing. If you’re using a more compact device with less power, then you might notice that it’s not cutting through what you’re cutting, and in order to continue using the tool, you’ll need to charge up and keep going.

What are some signs that DeWalt DC970 has a faulty battery?

Some signs that DeWalt DC970 has a faulty battery can be a power decrease, chargers not working or charging takes too long than usual, the drill is overheating, or it stops working even though the battery is fully charged. If the battery on your Dewalt DC970 starts to show these symptoms, it is time to replace it with a new one.


There are many reasons why the Dewalt DC970 battery may not be charging. If you’ve determined that it is not due to faulty wiring or the charger itself, then the battery pack has been damaged. There’s a chance that one or more of the battery cells have also been harmed. This can happen if one of them has a crack in it, for example, or they have aged out and need replacing altogether. You should consult DeWalt directly about this as their technicians will know what needs to go into diagnosing any issues with your power tool’s battery so they can recommend potential solutions accordingly. They can also suggest or recommend the perfect fit of battery for your tools when it comes time for battery replacement.
