In practice there's only about 3 makes of 2700mAh batteries that actually get close to 2700. Sanyo and Titanium brands for example. Everything above, and indeed most 2700mAh AA batteries are inflation by marketing Since most consumers are unable to test, and since most consumers probably torture their old batteries to near-death before buying new ones anyway, they always notice an improvement...

Even the mugen batteries, which seem to be highly regarded here, have inflated claims and don't come close to their stated capacity. The big ones with new cover have better capacity than Nokia original though


That ebay battery claiming to be made in Japan... Is that chinese text on it in Japanese font or what?
