Nicads and ni-mh are 1.2v per cell, instead of the 1.5 of alkalines, so that explains it nicely.

Given that most digital stuff works well at 1.2V and multiple batteries are used in series? There seems to be some collusion with battery manufacturers and equipment makers. I have dismantled a couple of devices ('kids' mainly) and the voltage regulation seems somewhat mendacious - nearly flat rechargeables would provide the power but the regulator seemed designed not to allow it.
May just be shit design, but I have a feeling battery manufacturers may be providing 'free' consultation.
