Wow! Didn't even know that was an option (AA's)...think the first of those Motorola flips that I had was a Ni-Cad. The brick that baked the whole side of your face while you used it that came previously was too.Good ol' analog.
Edit: Wait....I think the first BlackBerry I had that was Mobitex used a AA battery...and lasted about a month from a single battery!!!![]()
We had two of those phones (still do!) and we had big, fat high-capacity NiMH (I think they were NiMH, not NiCd), the slim battery (which was genuinely slim, the phone was actually shirt-pocketable with that battery) and one of these 6xAA cases for emergencies. That was one of the three greatest phones I've owned in 30 years of cellphone ownership.
