I suspect more "don't disappoint the users" than "harm to the device". From the Wikipedia AA article, not only is the nominal voltage lower (1.2V vs. 1.5V for both alkaline and cheap zinc-carbon), the "Max. energy at nominal voltage and 50mA drain" is *significantly lower: Alkaline = 3.90 Wh = 52 hours (3.9 Wh/50mA/1.5V = 52) ...

Two simple reasons. Different battery chemistries have different voltage and safety. Standard alkaline batteries are nominally rated for 1.5V, but they can have more than 1.6V when brand new and are considered to be discharged at around 1.1V or so, depending on application. Standard rechargeable batteries that are intended to be used in place of standard ...

Most likely reason I think is that when NiCd batteries discharge, they stay at almost 1.2V for most of their discharge cycle then go from 1.2 to 0 volts very quickly, so the low batt warning is unlikely to be on for very long if at all, and the player being unable to save the game, if it simply turns itself off with little to no warning. Since alkaline ...
