Question about Drills
These de0245 chargers are designed to detect certain problems that can arise with battery packs which would be indicated by the red light flashing at a fast rate.
If this occurs, re-insert battery pack. If problem persists, try a different battery pack to determine if the charger is OK. If the new battery charges correctly, then the original pack is defective and should be returned to a service centre for recycling.
If the new battery pack gives the same trouble indication as the original, have the charger tested at an Authorised Service Centre.

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.

When a Dewalt charger is showing a fast blinking red light it means the battery is no longer chargeable. It may be because of a bad cell or short inside the battery. Whatever the reason the charger will not charge the battery and it needs to be replaced.
