They're by LG. 3.6v 2200mAh is correct. Doubt they're much good for anything other than their original purpose. Most cylindrical Li-Ion have low discharge rates. There are a few out there that will do well though in higher draw applications. I have several old laptop packs I've dismantled. With 3 of the cells in series you can make a darn nice TX pack. I have three made from sony cells.
