I suppose a product like this one has a Sanyo original box or it was in the cardboard as sending an expo product or service (used). There were no instructions in French or the 2 buttons (on / off and soft) are useless. As soon as one connects to a socket, it starts to charge the batteries and if you press the On / Off button, it is useless, it continues to load. As for the Soft button, the different modes of load does not rule advantage. I have another charger at home, I paid less than 15 euros for 4 batteries, which ultimately is no more basic than this Sanyo charger, supposedly more sofistiqué
