I got these from the same guy I got the rest of my batteries from. However, he wasn't sure exactly what they were either. All I know is they hold a charge perfectly. I have had them for a few weeks now and they don't drop a charge at all. They also seem to put out more amps than the other Sanyo's that I have owned. In fact doing a ceiling bounce test I get the same lumens with these as I do the Sony 30amps and the Samsung 20r's.
Are these a Sanyo extra high amp battery? Any Idea what the mAh is?
The posted pics ring looks grey, while the linked pic shows a blue ring, but I assume youve noticed that and its just the picture not showing colour well.
