Reason 1: Wrong Type of Battery
The red flashing is considered as a warning sign that you have got a wrong battery.
A Dewalt lawn mower has particular specifications for the battery. And, getting a wrong one won’t let it connect with the mower. And thus, the red light warns the owner.
Solution: Get a Compatible Battery
The way to erase this issue is checking if the battery is the correct one or not. If not, getting a compatible battery as per the mower’s requirement is a must.
Reason 2: Lack of Charge
Lack of charge is a common reason that the red flash is not going away.
When you run the mower for a longer duration, the battery can be in lack of charge. In some cases, we forget to check first if it is charged or not.
Solution: Charge the Battery Without Delay
Noticing the red flash, you should hurry to check if it is related to the charging level. If yes, connect the battery to the charger and stay careful not to overcharge it.

The battery not providing any charge to the Dewalt lawn mower can let the red light flash.
It happens when the installation of the battery is not done correctly. An incorrect installation won’t be of any help in getting charge from the battery.
Solution: Install the Battery Properly
The red flashing will fade away when you install the battery in the proper method. I suggest you should look for it in the manual book as it carries the correct way.
Reason 4: Charger Not Working
The charger of your Dewalt lawn mower battery can go bad due to many reasons.
When it doesn’t work, the battery can not charge at all. As a result, the sensor can detect that and notify you regarding the matter.

To charge the battery like before, you should change the charger immediately. Because if the battery doesn’t have charge, the mower won’t even start.

A Dewalt lawn mower flashing red light also indicates the abnormal temperature range of the battery.
There are some air vents in the mower to keep the components in a normal temperature including the battery. But, when they get blocked with dirt, the battery starts overheating.

Fixing this problem is much easier as the vents are concerned. All you have to do is keep the air vents clean and clear.
