An offer in which one really finds all Varta button cells is ever class! I ordered the CR2032 - delivery took place within 20 hours - ordered afternoon 14am - 10 results clock in the morning on daurauffolgenden day (ie today) in the mailbox. All batteries have a 10 year shelf life - longer does not go. The first one I've ever now unpacked shows a voltage well above 3V is therefore fully charged.
