Most Common DeWalt Flexvolt Problems and How To Troubleshoot Them?

As already mentioned above, Flexvolt is a high-performance battery series offered by DeWalt.

However, certain users have been complaining about facing issues with their batteries.

From what we have managed to gather so far, they are all facing different kinds of problems with the battery.

This is why today, we will be focusing our article on telling you some of the most common problems that you can potentially run into while using these batteries.

We will also be listing all the possible solutions to each and every one of these problems. So, let’s not waste any time further and get right into it!

  1. The battery Isn’t Charging

Plugging in your battery on a charger just to see it won’t charge? This is actually a pretty common issue that we have found plenty of users to have come across.


However, it seems that there can be multiple reasons for the issue to occur.

In case you are also unable to charge your batteries, then one of the very first things that we recommend you check is whether the terminals of the battery are clean or not.

We have also seen cases where users haven’t simply plugged in the battery into the charger.

We also recommend you check whether you have fully plugged the batteries into the charger or not.

Lastly, you should also see if the batteries are being charged using a supported charger or not.

Each battery configuration requires a specific charger which is why it is crucial that you use the correct charger.

  1. The battery Won’t Last Too Long

Another pretty common complaint that we have seen various users make is that their batteries won’t last for too long.

As a result, they end up charging their batteries too often. If you have also noticed a decline in your battery timings, then you will have to start monitoring its behavior accordingly.

Start by checking whether you are fully charging the batteries. Also, you have to make sure that you always charge the batteries when they are at room temperature.

Charging them when they are too cold or too hot may lead to potential damage.

Lastly, it could be that your batteries have gone bad or have been used for most of their lifespan.

Just like any other electrical component, you will have to get the batteries replaced after having them used for a few years.

  1. Power Issues

Sometimes, even when the battery charges properly, and there are no issues with the uptime, the power from the connected unit is not optimal.

This can stem from a ton of issues with the battery connections as well as the unit engagement so keep that in mind when you do struggle with the power issues.

The first thing that you need to do here is to clean up the connection points as well as the battery compartment.

So, all you have to do here is to adjust the power system and streamlining the power flow by cleaning the connection points.


From there, you can check the compatibility of the unit with the battery. Not every battery has the power or the capacity to get through these errors.

So, all you have to do here is to ask the dealer about a compatible replacement.

Hopefully, it won’t be too much of a hassle to find a compatible system. So, be sure to check the situation with the compatibility as well as the connection points and then proceed with the setup one more time.

That will be more than enough as you try to adjust the power from the tools.

  1. Responsiveness Problems

Sometimes, even when the battery is new, it won’t respond to any tool, and you won’t be able to engage the system.

This can be most commonly linked to a drained setup. If you’ve used the battery past the 10 percent status and didn’t store it properly, then you’re likely to make the same errors.

All you have to do in this situation is to jump the battery one more time by connecting it with a fresh one.

That will be enough to help the battery respond to the charger as well as other power tools. So, grab a pair of wires and connect the terminals of a drained battery with a fresh one.

From there, you need to check the response from the battery one more time. It will respond pretty easily, and you won’t have to worry about more issues down the road.

So, be sure to jump the battery and avoid using it past the 10 percent status.

Otherwise, you won’t be able to secure a decent connection here, and the lifespan of the battery will also be reduced by a good margin. 

  1. Damaged Connections

The situation with damaged connection points is not that rare when you’ve not given any attention to the storage or the engagement of the battery into power tools.

First, you need to be mindful of the moisture and humidity levels in the region.

If the moisture is too much and you’re not too sure about the humidity levels, then you need to fix the system by finding a proper storage box.

The battery won’t respond well to harsh temperatures or moisture conditions in the storage room.

So, spending a few bucks to get a decent unit will serve you well in the long run. It all comes down to how you’re planning on maneuvering through the situation.

Every expert and professional will point you in the same direction.

From there, you won’t have to worry as much about the damaged connections or the rust building up on these points.

Hopefully, that will be it as you’re planning on maneuvering through the situation.

  1. Faulty Unit

Even though this purely depends on bad luck, many users have reported receiving a bad or faulty unit of battery from the get-go.

In simpler words, they seem to have purchased a faulty unit. Luckily, most units that you purchase from any retailer come with some sort of warranty.

So, in case you have received a faulty unit, then we highly recommend you don’t attempt any repairs on it all by yourself. In fact, you should opt for a complete replacement.

Simply contact the retailer from where you bought the batteries and try claiming the warranty. You should be able to get the batteries replaced without any kind of cost.

On the other hand, if you have been using the batteries for a while and they have recently started to act up, then they might have gotten damaged.

In this case, you will have to replace them with newer ones.

The Bottom Line:

While there’s no guarantee that you may run into problems while using the DeWalt Flexvolt battery, most of them can be troubleshot.

The article above explains all the common problems that users tend to face with these batteries, along with the necessary instructions required in order to fix them.

The majority of the issues mentioned here are pretty basic and easy to fix. As long as the hardware is in good shape, you won’t have to deal with more issues down the road.

So, be sure to check the unit for cracks and hardware damage.

If the Flexvolt system is damaged, you will have to rely on a professional to get through these errors.
