C-15 + 3 drill battery (potential) issue

[bowman32]

Last April I bought a new C-15 drill (4.2 A).  When I first received the drill, I charged both batteries.  One charged exactly as it (seemingly) should, while the other kept blinking red.  I e-mailed Festool and they indicated that it is normal and that it means it doesn't require charging.  I finally used my drill enough to require charging and that same battery is charging for a while and then blinking red.  The other charges and then the light stays green.  Is this normal?  It seems like it takes a charge, but I can't figure out why they're different?

Thanks
Eric

Welcome to the FOG Eric.  What you describe isn't normal from my experience with the five Festool drills I have owned.  You may want to contact Festool again.  A phone call is the most direct and thorough means to get this sorted out quickly.  You can find the phone on any Festool tool.

Thanks Bruce!  I'll do that tomorrow morning.

I had a battery doing that, turns out I just didn't push it on the charger enough. Now I use a bit of force and have no issue

I had a similar issue with the PDC I just bought.  Like Warner, the battery was not seating all the way in the charger.  After seeing similar issues on the FOG I tried again to push the battery in with no success.  Then I got a pen light and took a close look at the charger.  There was some kind of debris (maybe some black plastic shaving) in the recess where the battery seats.  I shaved down a popsicle stick and was able to dislodge it but I don't know where it landed.  At any rate, my charger works fine now.
