Abstract: A charging algorithm of lithium ion battery comprises at least one final stage wherein a maximum charging voltage is reached and the charging stops at said voltage. The state of charge or remaining capacity at the end of last discharging is measured and recorded, and said maximum charging voltage of last charging is also recorded. The maximum charging voltage of a new charging will be determined by said state of charge of last discharging and said maximum charging voltage of last charging. This novel charging algorithm provides longest possible cycle life for the daily used electronic devices while fully utilizes the battery capacity, and also fits the individual user's battery capacity consumption.

Abstract: A method of testing a secondary battery includes first to fourth steps. At the first step, the secondary battery after manufacture is charged to a first voltage. At the second step, a second voltage lower than the first voltage is set as a target voltage and discharge or charge is performed in a constant-current constant-voltage mode before the secondary battery is left standing. At the third step, the open circuit voltage of the secondary battery is measured before and after the secondary battery is left standing. At the fourth step, it is determined whether the secondary battery is a conforming item or not based on the difference in the open circuit voltage before and after the secondary battery is left standing.
