Just got off the phone with Ridgid customer service. I called to discuss the fact that Home Depot has the new 3.0AH 18 volt lithium batteries on display, but no chargers available for them. I told the rep, as you know?, charging a lithium battery in a nicad charger can lead to fire or explosion. I also told this to a worker in Home Depot who was wearing a Ryobi shirt and said he charged the Ridgid compact battery he was holding in the nicad charger. Brilliant, but where does this leave the general public or contractor who needs a 18 volt Ridgid battery and hasn't been reading this forum to know the dangers? They could post a warning sign above the batteries or pull them until the proper chargers show up. We've waited this long, for the sake of safety we could wait a little longer. I just don't want anyone to get hurt or possilby killed over a stupid mistake.
