stabilizes about 30 minutes after
charging has been completed. Therefore,
wait 30 minutes after charging is
completed before
measuring the open-circuit voltage.
Charging method using a variable-current
(voltage) charger
NOTE:
• Leave the battery unused for more than 30
minutes before measuring its open-circuit
voltage.
• Set the charging voltage to 16 ~17 V. (If the
charging voltage is lower, charging will be
insufficient, if it is higher, the battery will
be over-charged.)
