We start on the Duracell brand, a leader in the field for decades, so no real surprises. Obviously this kind of batteries are used in rather remote controls (it does for me) or devices to some intensive use, but for a long time. In loccurrence, for TV or stereo, it's the hair and no surprise, after a few days, to have a silent remote because the batteries were surreptitiously emptied ... The indicator "Powercheck" lets see if the batteries are empty (or if we can use the remaining energy on a unit less energy to finish them) and not to confuse them with old ones (kidding, but it happens more often than not !!!).
Special mention for packaging: it is made of cardboard, not plastic blister. Above all, it closes. More batteries "escaped" from the package and that roll across dan storage drawer. This is stupid, but it makes a big difference !!!!
