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.
Cold cranking amps (CCA) is a measurement of the number of amps a
battery can deliver at 0° F for 30 seconds and not drop below 7.2 volts. So
a high CCA battery rating is good especially in cold weather.
Reserve Capacity (RC) is a very important rating. This is the number of
minutes a fully charged battery at 80° F will discharge 25 amps until the
battery drops below 10.5 volts.
An amp hour (AH) is a rating usually found on deep cycle batteries. If a
battery is rated at 100 amp hours it should deliver 5 amps for 20 hours, 20
amps for 5 hours, etc.
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.
