3-2-2 Progress of Charging
The IC1810 starts a trickle charge under control of the MODE MI-COM (IC100). The trickle charge continues until the battery voltage
reaches 6.5V. At the point in time when 6.5V is reached, the IC1810 starts a 0.66A 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 80 mA
or less, the end-of-charging indication is provided. Thereafter, supplementary charging is performed for 24 minutes at maximum until
the charge current becomes 40 mA or less.

An error is indicated if the battery voltage becomes 5.7V 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.
