General Charging Notes
Fan: The charger is designed to control its cooling fan for efficient operation.
Consequentially, it is normal for the fan to start and stop when maintaining a fully
charged battery. Keep the area near the charger clear of obstructions to allow the fan to
operate efficiently.
Voltage: The voltage displayed during charging is the charging voltage and is usually
higher than the battery’s resting voltage.
CALCULATING CHARGE TIME
13.
Use the table below to more accurately determine the time it will take to bring a battery
to full charge. First, identify where your battery fits into the chart.
NR means that the charger setting is NOT RECOMMENDED.
Find your battery’s rating on the chart, and note the charge time given for each charger
setting. The times given are for batteries with a 50% charge prior to recharging. Add
more time for severely discharged batteries.
