Oops, another senior moment. And you're the one that taught me that over a year ago. Dang!

I have to agree here... I think you mean that there are both protected and unprotected IMR and ICR batteries.
IMR and ICR only stand for the chemistry of the batteries:
ICR = LiCoO2
IMR = LiMn2O4
IFR = LiFePO4
