1. Ensure that only NiMH AA rechargeable batteries
are used with the Apple Battery Charger, that
they are correctly installed, with correct polarity
orientation. If Amber status LED still ashes when
these batteries are installed, they are likely to be
defective.
2. Ensure that only NiMH AA rechargeable batteries
are used with the Apple Battery Charger and
were left charging for at least 5 hours. (LED will
go green when a full charge has been reached,
then will turn o to conserve energy).
3. Test with known-good AC duck head plug.
4. Quickly test customer’s Apple Battery Charger
for charge of a known-good set of NiMH AA
rechargeable batteries . If no Amber or Green
status LED is seen, replace battery charger (P01).

batteries for charge status when installed in a
known-good Apple Battery Charger. If no Amber/
Green status LED is seen, replace Apple battery
set (P01).
