This will happen if the
battery did not reach full
charge within 24 hours.

ies requiring more power
than the charger can de-
liver in 24 hours. Charger

may also be faulty.

The charger reached the
maximum voltage and is
reducing the current.
The charger detected an

No problem, this is a
normal condition.
