Our enhanced MAX product is now our undisputed number 1 in terms of longevity, thanks to recent improvements we've made. These modifications ensure the battery can withstand damaging leaks for a period extending to two years, even after it has been fully consumed. The MAX retains its power for an impressive 10 years when stored, positioning it as a reliable energy source when you need it most. It even outperforms the EVEREADY GOLD, lasting up to 50% longer in more demanding devices. Energizer not only innovates, but also prioritizes responsible energy solutions. We were the pioneers in creating the world\'s first Zero Mercury AA Alkaline Battery, an industry game-changer that demonstrates our commitment to powering people's lives in a more environmentally sustainable way.
