Lithium-Ion Batteries Replace Lead-Acid Across New Deployments
Vendors have shifted rapidly from lead-acid battery banks requiring frequent replacement and heavy site visits toward lithium-ion alternatives that last considerably longer and weigh a fraction of the equivalent lead-acid capacity, reducing both maintenance frequency and structural loading concerns at tower sites with weight restrictions across every deployment type and site configuration nationwide today. Roughly 44 percent of new telecom power system deployments in 2025 now specify lithium-ion battery technology, up sharply from under 18 percent just three years earlier as component costs declined enough to justify the switch industrywide.
