I bought a C12 off of ebay and received it yesterday.  The seller said it was unused and I believe him because it doesn't look like it's touched a screw.  I threw the batteries on the charger last night and couldn't get the green light to turn from flashing to solid to indicate that it was done charging.  I left it on for hours and it still was flashing.  I finally took the first battery off and put the second on.  Is there something I'm missing here?  Could the charger be faulty?  Has anyone else experienced this?
 
Call Festool USA for advice.  They might be able to help you troubleshoot over the phone.  Here's the number - (888) 337-8600.
 
Thanks David.  I thought about doing that but I figured I'd throw it out here first.  I'll give them a call later today.

If it has been unused for a long time it might be that the batteries have dropped really low in voltage and might take some work to get into full working order. I copied hte following from a manufacturer FAQ:

"Ni-MH batteries will self-discharge if left unused. Generally, within 30 to 60 days, batteries will become completely drained. When using them, you will need to first recharge them. After extended storage, you may need to condition the batteries several times to regain nominal performance."

 
Which batteries are you trying to charge?
How long was each one left on the charger?
What is the ambient temperature?

hi rnt80, which type of battery do you have ni-cd or ni-mh?

the ni-cd battery was put into production just after world war 2. i think it was invented in 1899.

it has its flaws, once the battery is completely discharged, i think they become useless.
i was surprised when festool decided to use ni-cd for their cordless products.

if you have the ni-mh version, you may be in better shape, if not, you are looking at 2 new batteries.

personally i never buy second tools, way to many negative stories, i prefer peace of mind with shiny new stuff.

not much help i know, but i wish you luck mate.

regards, justin.
