Item for detection
Battery connection
Time detection takes
10 ms

1 time = 10 ms
Conditions for detection
Constantly detected every 400 ms (when more
than a specified amount of charge-current is
flowing, this detection is omitted).

4 consecutive 200-ms periods = 0.8 s
Notes: 1. The timer for precharge 1 and 2 and the charge timer continue to count in the adapter-voltage standby
modes and battery-temperature standby modes. Counting by these timers restarts from the previous value
when charging resumes.
2. Detection of adapter-voltage abnormality (5.2/4.95/6.3 V) and battery connection is constant.
