I bought this item twice. The first time I was so disappointed at the poor quality I thought there must have been some kind of fluke at the warehouse. The level of power in these batteries was so low that they went dead extremely quickly. Because I have been a very happy Amazon customer for many years I concluded that a batch must have been misplaced in the warehouse and left so long they lost their power. So I bought a bulk batch again. This time the power level was so low that there were multiple times that I put new batteries in a remote control and they were dead when I put them in. And no, they were not stored at my house and lost their power. This happened within the first few months after the batteries were delivered. So I have determined that this has to be a pattern with this product and will never buy them again.
