Question about Dewalt 7.2-18.0 Volt One Hour Charger

Open Question

Dewalt DW9107 charger. Blinks twice rapidly, followed by a pause. According to the manual, this means the power source is out of limits (i.e. charging from an DC - AC vehicle inverter), however, it's still happening when it's connected to household 220. It always worked fine in the past.

SOURCE: Dewalt battery charger won't charge

As you know, solid red on your charger means that the battery is fully charged and the BLINKING red light means the battery is charging. Unless the light is blinking irradically everything is working the way it is supposed to. If the light is blinking irradically, the battery may just be too hot or too cold to charge ( like when you are driving many lags and your battery dies) and in this case simply wait 15 minutes to charge. If you get a fast blinking light still, the problem probably is with the battery.

SOURCE: CHARGER PROBLEMS

The flashing light indicates the charger is charging the battery (or attempting it) and if it never finishes charging you should try to charge a different battery, if the charger charges that one ok then the battery is bad.

SOURCE: DeWalt charger #DW9107 binks eraticly, even when

There could be a number of things wrong inside the charger, and could cause more problems trying to replace components on the board. Your best bet is to look on ebay or some other place to see if you can get a replacement charger.

On some chargers, when the light blinks rapidly, it means that the battery is bad. Try looking up charger information on-line.

Two quick flashes problem powerline what does that mean exatly


From the manual.

Some chargers have a Problem Power Line indicator. When the charger is used with some

portable power sources such as generators or sources that convert DC to AC, the charger may

temporarily suspend operation, flashing the red light with two fast blinks followed by a
pause. This indicates the power source is out of limits.

I can't find the charging manual and I am intuiting from the drawings that if it has a steady flashing red it means it's charging, but I would like to read the instructions.


Operator's manual for DW926K-2 is here. It doesn't specifically address solid red light, but that's what mine does when I first put it on, so solid red indicates that it is charging.

If it is flashing the red light with two fast blinks followed by a
pause. This means the power source has out of spec for the charger (such as a generator not producing electricity at 60Hz).

If the red light flashes long, then short, you're in Hot/Cold Pack Delay mode which means it won't charge the battery until its temperature has stabilized.

I hope this helps! If so, please vote. Thanks.

I purchased a new charger for my Dewalt Cordless drill and the red light just blinks. Is this normal


They usually have a little pic on there that tells you what the blinking means. I think it is charging, but sometimes it needs a green light too. Check it out. Mine flashes all kinds of signals, when it hits a dead battery, one that won't charge, it flashes something else. It only takes an hour to charge. Is the battery getting charged at all? Hope this helps.

Charger blinks twice red and then breaks and twice and keeps repeating . what does this mean?


There should be a diagram on the front right hand side of the charger that tells what each flash rate means.
