The batteries were delivered promptly. The packaging is just adequate: The 10-pack is supplied in a blister, which was closed by a strip of adhesive tape. It is a trimmed Universal blister strip, rather than one original Varta blister, as we know it from the supermarket. The button cells glued firmly to the tape. But that's all not so tragic. Only through this kind of packaging come to doubt whether it really is are original VARTA batteries. The Varta-typical label V 13 GA is the only possible reference to the manufacturer. For life I can not say anything because I bought these batteries in stock. The price of the 10 pieces incl. Shipping is certainly OK. When the batteries then work even long, I'm satisfied. Then it's me immaterial whether there are original VARTA button cells.
