Makita Battery Charging Problem

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

Battery infant mortality is a fairly common problem. Should be
replaceable under warranty. Normally box retailers don't do warranty
service but you might get them to trade the whole thing out if you try.
Otherwise, whatever Makita says for warranty service rules...

Its easy to kill a battery, a Nicads are discharged just when the
drill slows, running it down more can reverse a cells polarity, it is
also best to let a pack rest a day before recharging constant use is
hard on it.

Pretty much. Also one of the reasons everyone has moved away from ni-cd
batteries for cordless tools. I think most are ni-mh now with lithium
ion appearing on some now.
