ok ok .. calm down guys, electrical engineer on hand. Simply put, if you draw power from alkaline batteries, the current encounters more resistance than when drawing from rechargeable batteries. The voltage of the battery is like the pressure inside a hose. Imagine filling a tank, i.e. capacitor, using a hose :
Alkaline batteries = small hose, tap at higher pressure as they are 1.5V
Rechargeable = large hose, tap ar slightly lower pressure as they are 1.2V
Which do you think will fill the tank faster? From experience and maths, the large hose and slightly lower pressure wins. Besides, the voltage of rechargeables does not drop much during operation, unlike alkalines, which has an "almost linear" voltage drop starting from 1.55V down to around 1.0V when depleted. So, in short, rechargeable batteries are better, faster and a lot more economical.
