What is the Hot Cold Delay On DeWalt Charger?

Apart from offering power tools, DeWalt is also famous for giving away batteries. However, people who own these batteries have been asking around about a certain feature in these batteries.

There is no debate that these features add value to the system, but they can sometimes be complex.

More specifically, they have been asking about what the hot-cold delay on their DeWalt charger is.

This feature is in place to extend the battery life and help users keep the pack in good shape. However, owners are still not exactly sure how this feature adds value to their system.

If you have the same question in your mind, then you have come to the right place!

Using this article, we will be explaining to you everything that you need to know in order to learn more about these chargers.

So, without wasting any more time, let’s get started right away!

What Does It Mean?


For those of you wondering what hot-cold delay is, it is actually an important feature present inside DeWalt chargers.

This particular feature is to give the user an indicator of the battery either being too cold or too hot.

You will only notice the light whenever you attempt to charge your batteries while it’s too warm or too cold.

It is just an indicator light used to give you a better idea that you should let your batteries cool down or warm up before charging them.

That being said, after seeing the indicator, we highly recommend checking the batteries. You can check whether your batteries are hot or cold.

Depending on their temperature, you can then let them cool or warm up.

If the delay indicator turns on every time you try to charge up the device, then you’ll know for sure that you’re not storing the battery properly.

service and repair

There are a ton of things that you need to keep in mind regarding the maintenance of your units.

Proper storage is the most essential aspect of maintenance, and you need to find a dry and isolated spot.

Extreme raptures, moisture, humidity, and pressure on the unit will only damage the pack. So, you need to invest in some decent storage boxes if you need long-term performance.

From there, you won’t have to worry about the delay light coming on when the battery temperature is not right.

So, keep that in mind and make sure to properly store the battery if you wish to avoid these delay issues.

With that said, be aware that the reason why you keep getting this indicator might have something to do with an ongoing fault with your battery.

Normally, the battery should start charging after a while as soon as it cools down or warm-up.

How Long Does This Delay Last?


In most conditions, the charger won’t start engaging the unit for around 20 minutes.

If you’re sure that the environmental conditions are not that extreme, this 20-minute delay is usually enough to adjust the battery temperature.

On the other hand, if the conditions are not that favorable and the temperature is too low, then you will have to wait a bit longer.

So, it all comes down to the environment around the workshop, and you need to move towards a more stable temperature.

However, this indicator doesn’t always mean that your battery is too hot or too cold. If you feel that the temperature of the battery is optimal, then there might be something wrong with the charger or the battery.

Most of the time, you just have to do a bit of cleaning on the terminals to fix this error.

What If My Batteries Don’t Charge At All?

As explained earlier, there can be cases where your batteries don’t charge at all, even after waiting. In this case, it is highly likely that you have some sort of faulty battery.

You can determine whether the battery charger is working by turning on the charger.

You will run into the same situation when the battery is completely drained. Even if you’ve purchased a new battery and it has only been in use for a week, then you might have to jump the battery.

This is especially true if you like to use the battery even if it is under a 20 percent charge. So, if you’re in this situation, you need to grab a different battery and a pair of wires to set up this system.

There is simply no point in bothering with any extra steps, and simply connecting the drained battery with a charged battery for 15 minutes will do the trick.

From here, you can reconnect the battery to the charger, and you won’t have to worry about the same light indicator. After this point, you need to make sure that the battery status never goes below 20 percent.


Giving the battery sufficient time to charge is much better than getting a few extra minutes of performance immediately.

Otherwise, you will be spending hours trying to engage the battery with the charger. Moreover, the battery performance won’t be that great either.

If you get a red LED light, then this confirms that the charger is indeed working. Though if you do have trouble charging the batteries, we strongly suggest getting them checked by a professional.

There is no point in wasting more of your time when you can’t get any response from the battery.

Either the charger is defective, or you’re dealing with a dead pack. In both conditions, we suggest that you seek professional support.

That way, it will be much easier to narrow down the error. You can also take the unit to a repair center or claim the warranty on the charger.


The DeWalt chargers and battery packs are fully supported by a solid warranty. So, if you do run into issues with these units, it is not that hard to get a new one.

All you need to show is the proof of purchase, and everything else is simple after that. So, keep that in mind and go with the official support when you can’t seem to fix the issue.

Hopefully, the issue will be fixed as soon as you’re in possession of a new pack.

The Bottom Line:

What is the hot-cold delay on the DeWalt charger? It is a vital feature present in most DeWalt batteries and is used to tell the person that the batteries are currently too cold or too hot.

In most cases, it is just used as an indicator queue and should be nothing that you need to worry about.

However, if you do find that the indicator is engaged for more than 40 minutes, then there is something to worry about.

There might be something wrong with the battery, and you need to check the terminals before anything else.

A bit of cleaning will go a long way when you’re trying to secure an optimal response from your power tools.


So, be sure to service the pack and then follow through with cleaning methods to get ahead of minor problems with debris and gunk getting stuck between the device.

Once that is done, you can also try to jump-start the battery with a different one. Hopefully, you will be able to secure an optimal response from the unit after going through some of these fixes.

From there, you won’t have to worry about the delay light staying on for hours on end.
