I suppose this is the most appropriate place to ask about batteries...
I am talking about your standard home or discman-use batteries (A,AA, AAA etc.) Many of my AA batteries are in the need of being replaced. I have noticed that Nickel Metal-Hydryde (NiMH) are slowly replacing NiCD batteries. What is the difference between a NiMH and NiCD battery (besides the chemical element)? Do the NiMH suffer from the memory effect as well? Is there a higher ampere capacity? Besides, can anyone explain me why the standard rechargable batteries (AA, AAA) always come in 1.2V instead of 1.5V?
