A failing hybrid or full electric ESS doesn’t always mean full replacement. Altertek’s innovative regeneration process can restore ESS units from a wide range of manufacturers to safe, reliable operation, often extending their service life by several years. Using proprietary diagnostics, custom-built equipment, and advanced reconditioning techniques, we recover performance from systems previously considered end-of-life. This eliminates the need for costly replacements, reduces vehicle downtime, and significantly cuts environmental impact. Our approach keeps fleets moving while avoiding unnecessary waste, delivering measurable savings for operators and supporting the circular economy. It’s cost-effective, sustainable and changing how fleet battery systems are managed.
