ZincFive Hits 2GW And It’s Quietly Rewriting the Rules of Data Center Backup Power

Lead-acid batteries are heavy, lithium-ion batteries are flammable, and both technologies have been the unglamorous backbone of data center backup power for decades. ZincFive just quietly passed a milestone that suggests nickel-zinc chemistry deserves a much more serious look from data center operators: the company has now surpassed 2 gigawatts of power delivered or contracted globally.

Nickel-zinc batteries offer high power density, superior safety (no thermal runaway risk), and lower lifecycle emissions compared to both lead-acid and lithium-ion all in a more compact footprint. For data centers where floor space is at a premium and the consequences of a battery fire are catastrophic, these characteristics are increasingly compelling.

ZincFive’s expanding portfolio includes the BC Series including the BC 2 AI battery cabinet designed to support both traditional backup requirements and the dynamic power demands of AI-driven workloads. They’ve also launched a NiZn Retrofit Kit that lets operators upgrade existing lead-acid systems within the same cabinet footprint, reducing cost, complexity, and disruption in brownfield data center environments.

CEO Tod Higinbotham framed it simply: “Surpassing 2 gigawatts reflects both the performance of our technology and the confidence our customers place in it.” That’s a notable statement from a company that started as a battery technology startup and is now being recognized alongside industry giants on TIME’s lists of America’s and the World’s Top GreenTech Companies.

The 2GW milestone is more than a number. It’s proof that a battery chemistry that was once considered a niche technology is now being taken seriously as a mainstream alternative in one of the most demanding and mission-critical environments in the world.
