I don't understand. My 183-92s batteries have been dead for almost a
year now but it hasn't prevented me from using the machine. I simply
 removed the battery pack and use it exclusively on ac with the
powerpack. I have had no problems doing this.

This is why i didn't bother to buy new batteries. Given the deficient
design of the machine (the fact that the batteries are always charging)
I could see that the new batteries were just going to get trashed the
way the originals did. And you are right, using it off batteries until
they die is not the way i want to use my machine. I usually have access
to ac and prefer to have the machine plugged in. The batteries (when I ha
had them) were a nice backup when the power went off or for those rare
occasions when i didn't have access to ac. Ironically, it is the fact
that i always used ac rather than the batteries that destroyed the
batteries.
