I've bought for my wireless weather station and several remote controls me these batteries. The first charging cycle in nursing program my charger BC-700 from Techno Line 2 of 4 batteries were no longer recognized. In order to evaluate the whole thing, I went with the Akuus a Elektonikfachgeschäft, even there the Akuus were not recognized. The remaining 2 batteries of the pack contents work perfectly. Now, after the third loading cycle in the maintenance program of the charger, both remaining batteries have a capacity of 1046mAh, which in my opinion is in the range of manufacturing tolerances. I would like to mention the outstanding support provided by the company Ansmann who has taken on its own contact with me and has made a replacement of the article and called me for the application above mentioned recommendation for a more suitable product. This I will try soon.
