Google’s Data Centers Just Got a Major Battery Upgrade
Google swapped out old lead-acid batteries for 100 million lithium-ion cells in its data centers. These new batteries hold twice the power and take up half the space, freeing up room for more servers. The shift slashes the number of backup cells by 75%—a game-changer for efficiency. Meanwhile, Panasonic has shipped over 10 billion lithium-ion cells from its Nevada factory since 2015. Batteries aren’t just for EVs—they’re reshaping entire industries.
