CALCULATING CHARGE TIME

Use the following table 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.
CCA = Cold Cranking Amps
RC = Reserve Capacity
Ah = Amp Hour
NR means that the charger setting is NOT RECOMMENDED.
Find your battery's rating on the chart below, 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.

Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery clips,
cords, and the charger case.

Ensure that all of the charger components are in place and in good working condition,
for example, the plastic boots on the battery clips.
