Duracell Ultra AA alkaline batteries with high performance cathode technology.
Duracell Ultra provides up to 40% more power vs Duracell Plus*
Duracell Ultra batteries have POWERCHECK, an integrated tester that always let’s you know how much power is left in your battery.
Duracell's DURALOCK technology means these batteries are guaranteed to stay powered for up to 5 years* when not in use. This huge leap forward in battery technology has been made possible by improvements in the purity of ingredients and upgrades to the construction of the battery cell meaning less power is lost when in storage.
