Very surprised by the contents of the package. Each battery is in a rigid cover. Good point. Avoid accidents discharges or short circuit when storing batteries in the backpack (for example) Ideally suited to the type of appliance that I own Nikon The ability (lifetime use "normal" - photo summer - not too de'utilisation Flash, ...) is very good I alternated (during holidays) between Nikon battery and 2 batteries ENE12 without detecting differences when utilsation Nikon
