When clusters of GPUs ramp rapidly between idle and full utilisation, they create sharp power spikes that can occur repeatedly throughout normal operation. These dynamic power events place new stress on battery systems designed primarily for energy capacity rather than repeated high-power cycling.
Lithium-ion batteries, for example, excel at storing large amounts of energy relative to their size. But repeated high-power discharge cycles can generate heat that accelerates degradation and reduces long-term performance. In practice, operators often compensate by oversizing battery installations to maintain reliability and lifespan.
This overbuild not only increases capital costs but also consumes valuable floor space inside datacentre power rooms – a growing concern as facilities push toward higher rack densities and more compact infrastructure designs. Nickel-zinc behaves differently. Because NiZn cells have inherently low internal resistance, they can deliver very high power quickly while maintaining stable operating temperatures.
“ One of the advantages of nickelzinc is that we don’ t have to choose between traditional back-up power and AI performance,” Brandon says.“ The same system can handle both.” zincfive. com
