I bought this button cells for my little glass angel in a Christmas ball. This requires them three pieces, to shine at Christmas time in changing colors. The batteries when buying were quickly all and so I needed replenishment. The batteries were delivered immediately after purchase by mail. The capacity is roughly equivalent to those that were already in the purchase of the ball. These were, however, no brand batteries, so I can not say anything in this regard. For me, the capacity and the lighting duration of the sphere is absolutely ok. In particular, just when you look at the price-performance ratio. If my purchase the 0.1425 euros per battery and still included the postage would. Noteworthy also is still very fresh goods. The size indicated on the package shelf life is four years in the future. Personally, I am absolutely satisfied with it and I am sure that my little Christmas Angel is so light for many years at Christmas time.
