I had some years ago acquired for an old appliance Panasonic one second backup battery; which had been delivered with a small box of rigid plastic storage perfectly suited to the size of the battery, giving him a perfect protection without bulk. Times are changing ... I now get this protection for any battery with a shabby soft transparent plastic bag near zero quality. Considering the price at which sells Panasonic batteries, it is petty to him and not very elegant with respect to its customers. Before this dilettantism we regret not having opted for a battery "generic" three to four times cheaper; probably without box (at this price) but it is not shown that the quality would be proportionately lower.
