Telecom networks run on distributed lead-acid: strings of VRLA batteries at tower sites and exchanges, replaced every five to ten years as a fact of life, and in three to five years at sites that cycle daily on an unstable grid. Each replacement is a truck, a technician, lifting gear, a disposal chain and a site visit that costs more than the batteries on it, multiplied across thousands of sites for the life of the network. Lithium replacements have arrived with a competitive first cost and a fire-code conversation the tower owner never had to have before. The battery line in a network's operating budget is really a transport line.
The Energy Core is designed for this duty: 30 kWh at 48 Vdc, built for the telecom DC plant, natural-air cooled, IP21, on a cell designed for 30,000 cycles and 30 years with no equalisation, no watering and no technician cadence. The chemistry is aqueous and non-flammable with zero risk of fire from thermal runaway, at unstaffed sites where a battery fire is discovered by the outage it causes. The daily cycling that kills lead-acid in three years is inside the design envelope. The Energy Core is a product on our roadmap for distributed and remote sites, and this page describes the job it is built for.
The replacement events come off the thirty-year plan, and the truck rolls, the disposal chain and the swap-outage risk go with them. One procurement against three or four. Site by site, the comparison stops being battery price against battery price.
