Title: Don't Be Fooled
Review: This is a AA battery in a D size case. It will last less than half the time of a "real" D size NiMH cell. The power available from a battery is indicated by the mAH rating, with more being better. The price of this item looks good until you realize you are paying for a D cell and getting AA performance.
