I don't know if this is a known fact or not, let me know if it is, but I found this fascinating.

My old CC had one of the Rayovac 4.5V batteries on the logic board. One of the new ones I got on Friday has a 3.6V half-AA battery! I've never seen that in a CC before. The manufacture on that one is February 1993 as opposed to my other CCs which are both summer 1993.

Anyone else familiar with this oddity?
