Anker AA4 battery

Long-Lasting Power: Power small devices like remotes for up to 240 days, or keep toys and game controllers running for much longer than other brands are able to. PowerLock: An air- and liquid-tight seal keeps the power inside; until you’re ready to unleash it. 10-Year Shelf Life: Buying batteries in bulk never made more sense. Anker Alkaline batteries work flawlessly for up to 10 years after they are first purchased. Adaptive Output: Anker Alkaline batteries deliver only the power required by your devices, ensuring universal compatibility and long life.
