Hi!

I just bought a Makita BDF452HW about two or three months ago and
having a problem charging the battery. The one battery charges fine,
but when I put the other battery in, the charger lights flash green
and red alternately. From what I can see, this means that the battery
is broke.

The battery model number is bl1815. I was wondering if there was a
simple way I can "reset" the battery to fix this. I bought the drill
from home depot and I suppose I could go back there, but I doubt they
will do anything to help me. I also could not find a customer service
email on the Makita page. There's service centers, but I would hate
to bring the battery there because it is a drive from my house.

Thanks in advanced for any help!
Mike
