At the time I bought the batteries, because I know from long experience already VARTA ago and actually was always amazed by the longevity (of course, at a correspondingly high price). Since it accesses logically, if you can buy 40 batteries at a super low price. Now that I've used up more than half of 40 batteries or better: had to use up, I have to say that the batteries are quite cheap, but also correspondingly short-lived. And I have not even used in "energy guzzlers", but only in a LED flashlight and a milk frother. Especially when I had to watch frother that I every 2 when not once-daily use - 3 weeks, the batteries had to replace. I've gotten batteries in the milk frother - for 3 months without loss of performance and without new Loading ... This VARTA batteries I do not buy! Not advise
