Independant AA Battery Capacity Comparison

'Super Power', 'Lithium', 'Digital Power' AA batteries are given lots of labels to convince you that they have more power capacity than other AA batteries - but which are really the best? Or, which battery has the best capacity/cost ratio? This article performs real battery draining tests to answer these questions. We will show the exact setup used to conduct the tests and give you the results uncensored or biased by ANY prior affiliation with any of the battery companies.,

Our setup will be the simplest possible circuit: the battery in series with a resistor. The resistor limits the drain current and provides the draining load. Several resistive values will be used to see if the batteries have different performance in different drain situations.
