You might be right about the terminology, but I bought a generic battery charger from Harbor Freight, and from the charging specs it seems clear that there is something significantly different between IC3 and NiMH. The mAHs of the IC3s are 2000, and some 15 minute batteries are 2200 or more. The rating for NiMH is only 1300 for AAs. I know that using the wrong charger can cause batteries to explode, although I doubt that would happen with this. At best, it would take much, much longer to charge the batteries, and may effect the lifespan.
