Again and again one can read of short service life with batteries - but this is not the product itself but on the (dubious) dealer. Some traders (including those with many positive reviews) ship here obviously old and therefore not original packed batteries.
Having already received several batteries without original packaging and these have failed regularly after a short time, I accept only supplies in the blister package (see photos above).
My current supply came by the way of "Gina-energy-store", the batteries were boxed and new (best before 01.2022) - so it should be.
