hoffumAdvantages and Applications

HOFFUM lithium-ion batteries are ideal for both telecom towers and data centers. Telecom tower batteries can be charged from the electrical grid or powered by renewable energy in off-grid locations, while batteries for data centers offer a backup electricity supply for added security. These batteries are essential for data integrity and continuity of communication and transmissions, but up to now, sustainable options have been lacking.

HOFFUM offers sustainable telecom batteries that are durable, reliable, and cost-effective. They can be used to collect energy from traditional electrical grids or renewable sources; this energy can be either stored until an outage occurs or it can be used to control utility costs by storing energy for use during peak consumption times, when rates are higher.
