Schade ... 2/5 of the pack already did not have the full capacity

At least 2 of (40%) supplied batteries 5 had no longer sufficient capacity. Unfortunately, I have noticed this immediately, since only gradually, demanded the other detectors of the alarm system, the use of these batteries with a new battery. An examination with a "normal" or charge Spannung- test device was not possible in advance, since this voltage with the device is not available to me measured. Thus, it is only now was able to determine the lack of charge, since my alarm right after inserting the battery as "insufficiently charged 'reported. Only complaint was no more now, of course, possible. Even if the 5 Pack may seem inexpensive at first glance, it is in arrears then but expensive in the number of rejects. And how long will the batteries last is set (the first assembly by the manufacturer has maintained for 3 years), will make then too late to get out. Seeking me definitely another seller who then hopefully other goods has.

Update: I've now bought identical batteries with another vendor and they were all ok, if a little expensive, but not least 40% of waste. (!)!
