AFAIK AW is not a rating but rather a manufacturer of IMR batteries.
AW is a rating its like the CE rating of approval for use
What? No, you're wrong. AW is a battery vendor in China named Andrew Won. He buys large quantities of batteries from the likes of Panasonic and then puts all of them through a series of tests to grade them. (Batteries are not created equal) He and his folks separate the best from the rest. Only the best IMR batteries get the red wrap and AW sticker, while only the best ICR batteries get the black/silver wrap and AW sticker. They are then sold as the
AW brand of batteries.

The buying and re-wrapping of batteries of other manufacturers is extremely common in China. Most batteries are manufactured in Japan, Korea, or China. Many of the batteries originating from China are of varying quality, mainly because some of the vendors obtain used batteries harvested from old laptop computers, wrap and sell them as new, or are the rejects of the better battery brands and re-wrapped as another brand or sold as a generic no-name battery. This is why battery experts advise to only buy recognized name-brand batteries to assure purchasing a quality battery. The counterfeit trade for batteries is very active in China, also; therefore it is important to purchase from authorized battery vendors.
