I own a Pro95 and use NiCad batterys and recharge em in the scanner (using the yellow battery pack). I have bought a seperate "intelligent" charger and NiMH batteries. I was wondering if I could continue to use the yellow battery pack ... and just not use the AC Adapter anymore. I know that the primary difference between the black one and the yellow one is that the black one won't charge if you plug the ac adapter in ... just as a "safety" feature in case you have non rechargable alkaline batteries. Is there any other difference? Would there be any other disadvantage to continue using the Yellow pack, but not using the AC adapter ever? the reason I ask, is because I can't find my black battery pack
