112 +In "By effective capacity" mode SOH is calculated as a ratio of effective capacity to nominal capacity. Effective capacity is estimated to DOD value when battery SOC reaches 0%, so SOH is recalculated each full battery discharge.

114 +In "By total charge-" mode SOH is calculated as a linear function of "Total charge-" counter. While "Total charge-" constantly increases during battery operation, SOH will be linearly decrease at the same time. This mode requires a confirmed data about cell health depending of amount of discharge rate to configure the linear function.
