Battery Degradation

by iot.halowerk.com in Productivity & SaaS

x402 APIPassing, checked 3 h ago

Applies a transparent heuristic: cycle fade scales with equivalent full cycles and depth-of-discharge exponent; calendar fade scales with square-root time and a temperature factor. Coefficients are caller supplied or declared defaults. This is not cell-chemistry validation, warranty advice or a safety prognosis.
