After I initially got the wrong battery (after you have correctly stated designation), the right spare me was quite easily sent, the left also be used easily and reliably engaged. Unfortunately, this has remained the only plus point. The persistence was from the beginning not much better than those who are still able to afford the many-year-old original battery. And after a few weeks they had power even to even. After less than a quarter of the battery was just garbage. After the original has persevered for many years with me, so I can only advise against this part.
