I wouldn't be suprised if the new Apple AA-loader will only work with
Apple AA-cells.
Same as my Uniross batteries, they just load with the Uniross loader. 8(

Raychem(?) once had sold rechargeable alkalines, and their charger
worked only for them.
The "secret" was in the design of the "button" at the + side of the
cell, in combination with the hole in the charger for that "button";
subtle differences that made things look the same - but different enough
to pervent contact if other cells were tried.
