Abstract: At least one electrochemical cell is charged to a predetermined voltage of the electrochemical cell using an external power source. A charging current of the at least one electrochemical cell is monitored. An increase in the charging current is detected at the predetermined voltage of the at least one electrochemical cell. It is determined that the at least one electrochemical cell is in danger of experiencing a performance decrease based on the detected increase in the charging current.

Abstract: In some examples, a host device includes a battery capacity and/or battery resistance predictive model. The host device may predict a battery capacity value and/or batter resistance value of a rechargeable battery and compare the predicted battery capacity and/or predicted battery resistance to a battery capacity value and/or battery resistance value stored in a fuel gauge. The host device may overwrite the battery capacity value and/or battery resistance value stored in the fuel gauge with the predicted battery capacity value and/or the predicted battery resistance value if the difference is greater than a maximum error threshold.
