In brief: I have now the battery twice. An Amazon, a purchased before from another source some time ago (but myself manufacturer). The older battery has about 50 (now well over 100) persevered with me in a relatively short time charging cycles without significantly losing performance. The battery runs and easy runs and is compared with the original spare battery now even cheaper. The second, newer battery are similar. If upon further intensive use (but) still set problems, then I will follow through here accordingly, been here indicated, however, nothing of. Also, holding the charge for an extended period has hitherto never been a problem.
