General Charging Notes
Fans: The charger is designed to control its cooling fans for efficient
operation. Consequentially, it is normal for the fans to start and stop when
maintaining a fully charged battery. Keep the area near the charger clear
of obstructions to allow the fans to operate efficiently. NOTE: The charger
has thermal protection, and it will shut down if it gets too hot.
Voltage: The voltage displayed during charging is the charging voltage
and is usually higher than the battery’s resting voltage.
