3-2-2 Progress of Charging
The IC3201 starts a trickle charge under control of the SUB MI-COM (IC100). The trickle charge continues until the battery voltage
reaches 6.17V. At the point when 6.17V is reached, the IC1800 starts a 808 mA quick charge. Then, the charge current decreases
gradually with the progress of charging (because of an increase in impedance of the battery). When the charge current becomes 70 mA
or less, the end-of-charging indication is provided. Thereafter, supplementary charging is performed for 90 minutes at maximum until
the charge current becomes 34 mA or less.

An error is indicated if the battery voltage becomes 5.5V or lower during quick
charging or constant-voltage charging.
An error is indicated if the battery temperature is not within the range of
−10 C to 52.5 C.
