Just a point on terminology. Two of these posters used the term "amp" when they really meant "amp-hour". You cannot generate an amp of electricity in a given amount of time, since an amp is not a quantity of electricity - it is a rate of current.
It''s kind of like a land-lubber saying "we were going 10 knots/hour". Any sailor knows that "knots" already contains the notion of "per/hour", so adding it to the end doesn''t make sense (actually it does if you''re talking acceleration, but that would be a pretty unusual discussion).
