The reviewed here 1.5 Volt AA batteries "Ultra Power" come in handy twelve pack and fit in many household appliances usual.
Whether they, as the manufacturer promises, are actually 10 year storage capable without losing charge, of course I can not judge because I do not care me to stockpile on soo long time, but in any case are Duracell batteries significantly not perishable like so some of my already purchased cheap batteries that were partially empty or at least weakened considerably after a relatively short time spent.
For this purpose, my holding the slightly higher price with brand batteries is certainly worthwhile, so that I forgive full marks here.
Whether the "Ultra Power" but actually keep batteries from Duracell even longer than I usually purchased "PlusPower" I can not judge yet, unfortunately.
Should I actually find significant variations in life, I will not grudge here.
