AAA4 small alkaline battery

Long-lasting energy: operate small devices like remote controls for more than a year, or keep games and game controllers running much longer than other brands can. PowerLock: air and liquid leak-proof prevents energy from escaping; so you are ready to unleash it. 10 years of lifespan: buying batteries in bulk has never been more logical. Anker Alkaline batteries work flawlessly for up to 10 years after first purchase.
