Have I recently bought this battery instead of the expensive original batteries from Siemens (about 2/3 savings). The original has kept only 2 years. So far I'm very pleased with the favorable battery and if it fulfilled his life expectancy, I remain, too. However, I must confess that I used to back in the evening put the handset again and again to the charging station, even though the battery was not yet empty. This has perhaps led to a so-called memory effect, so that the battery has not fully charged until he finally gave up the ghost. This time I'll do it differently: I place the handset only to the charging station when the battery charge is coming very the end or when the handset indicates to me that we should put it on the charging station. Let's see if the addition helps to stabilize and prolong the life. :-)
