Go to page 8 and tell me why the bold characters clearly state that it is not possible tu charge two battery pack at the same time with two different memory location ! They don't talk about two different batterie type at all. So if we all use it all the time and it works, what's the reason for that ? That was our questionning at our club meeting yesterday. Peoples want to discuss that more at the next meeting so I tough that I could search and find an explanation.
