Perhaps someone can educate me on the two styles of charger timer decals. One goes from "Start" then uses letter of the alphabet around the dial. The other uses "Start" then designates other starting points based on the age of the battery pack. I have found no description in any literature about the alphabetic style decal. I always felt the "battery pack" decal was more intuitive and probably succeeded the alphabetic one. However, this morning while replacing the broken mounting plate for the timer (aren't they all broken?1) I noticed two decals so I peeled off the alphabetical one to find a "battery pack" one under it. Now I am confused as to which decal design was first!
