Hi Rodalco,
You forgot to see my curves of battery voltages.
The voltage from a 1.2V Ni-MH cell is higher than the voltage from a 1.5V alkaline cell for most of the time. They both have the same capacity to 0.8V but when the Ni-MH cell is still at 1.2V the alkaline cell has dropped to 0.9V.
Go to www.energizer.com and look at their detailed datasheets for all their batteries. They show Ah capacity and discharge rate under many different load conditions.
What do you mean by 'facts'? Data sheets? Discharge curves? Just go to any manufacturer's (e.g. Energizer, Duracell, Sanyo) web site and click on technical info or engineering guide; they all have fairly detailed pdf data sheets.
One day when I was at the store they had NIMHs in the clearance bin, the upc was messed up, I got 4 packs of 4 for 99 cent each, (Later found out they were 14.99 )
