These are the 4th generation data stacks to withstand 2100 charge cycles against the 1,800 cycles of those of the third generation still available on Amazon. Despite the acquisition of Sanyo by Panasonic they kept the name of Eneloop and especially the same quality. I needed to transport boxes and this lot only slightly more expensive than without me satisfactory. 2 articles ordered received in blister as the picture always made in Japan, production of quality. The case is really tough plastic, for it is not against white semi transparent white opaque but without the brand logo. Minor issue for me, the only thing I could criticize is that it is quite difficult to open but at least no risk that the batteries from escaping during transport. I have placed several orders with the seller iCell Limited which has always been very serious, articles from England in bubble envelopes the average delivery time is 1 week but given the price and the near impossibility of finding these products in France waiting is not a concern. Charger used: RS 720 LA CROSSE TECHNOLOGY.
