Both of the charge retention over weeks and months, as well as by dre capacity I can only say one thing: I am absolutely thrilled about the reliability of these batteries!
Certainly I have also been lucky and never "caught" during my several individual orders the batteries from the "WH" -Charge who were by now well-removed from the market and are probably replaced if necessary by Varta for free, reported as other reviewers here. In my opinion, the fall in overall average rating here to negative, probably because is always evaluated negatively if something does not work and those in which "everything is fine" rather tend to show restraint ...
