Among the AA cells the Maha IMEDION have the best 4-week results. The Kodak are respectable second, and low price and high availability will make them the preferred choice for many.

The GP Recyko AAA cells exceeded their name-plate capacity after four weeks! It appears that in general the AAA market has had less of a capacity horsepower race than the AA market, leading to more concervative ratings.
