Good ad but I have use the Sanyo 2500 and so far not a single problem. Have tried to leave it for a week and it does show some drop about 2-3% but not totally discharge. Sanyo is the way to go man.......!
Check out the marking on the bottom of the cells. There is a HR engraved. Also the nipples of the Sanyo batteries are bigger compared to other manufacturers. Sony, Kodak, Fuji, Olympus, Energizer have their batteries made by Sanyo.
correct me if I am wrong, I thought aony is also made by Sanyo?
