Anker Alkaline Batteries The Premium AAA Batteries with PowerLock Technology. Brought to You By Anker From high-speed chargers to cables that last for life, to batteries equipped with a PowerLock ring that keeps power sealed away for a decade; Anker is the global leader in mobile power. Adaptive Power Anker batteries deliver only the power your device requires—no more, no less. This means that they work flawlessly with any device that takes AA/AAA batteries. PowerLock An interlocking mechanism and sturdy rubber seal prevent all leaks and ingress into each battery's essential components. PowerLock keeps all the power safely inside the battery's casing until it's ready to be used. Power for a Decade Anker batteries retain their power for up to 10 years, but ordinary batteries suffer from constant passive power loss, making Anker the superior choice. Buying batteries in bulk has never made so much sense.
