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

Adapter voltage 1
Constant detection (whenever charging has
stopped)
Adapter voltage 2
4 consecutive 50-ms periods = 200 ms
4 consecutive 200-ms periods = 0.8 s
Constant detection (during charging)

Adapter voltage
3a/3b
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.
