Why is the battery health “good” but the battery does not hold a charge?
There are two factors involved. The Battery Health indicator provides a check of the charge capability of the cells in the battery. The Storage Capacity indicator provides an accurate overall status of the cell storage capacity. Even though the cells in the battery can be charged, the storage capacity of the battery cells may have degraded. If the Storage Capacity is rated as Green or Green-Yellow, and the Health is rated as Good, the battery is operating as it was designed.
