Long-term reliability is engineered into every cell, and our cycle and calendar life management program protects both performance and customer value over time.

Two Dimensions of Battery Life

Battery life is understood in two ways: cycle life, measured by repeated charge and discharge, and calendar life, measured by how the cell ages even while stored. Both matter to customers, so we design and test against both rather than optimizing only for initial capacity. A cell that looks healthy at delivery can still disappoint after a long shelf period, which is why calendar aging is studied as carefully as cycling.

Testing That Predicts Real Aging

Our lab runs controlled cycling, storage and environmental tests to observe how capacity and internal resistance evolve. These results guide chemistry selection, charging limits and protection settings before a design is released to production. We track capacity retention and internal resistance trends across large sample groups, filtering out variations that would otherwise show up later as inconsistency.

Turning Data Into Customer Value

Reliability engineering translates directly into fewer early failures, longer product warranty confidence and better end-user satisfaction. By managing degradation deliberately, we help customers build products that stay dependable across their intended lifecycle.
