Charging Tips
Read this entire manual before using your battery charger. The following
tips serve only as a guide for specific situations.
If your vehicle won’t start
•
– It is not necessary to fully charge your
battery to start a vehicle. When the battery’s charge is 77% or more, the
battery has usually been charged enough for the vehicle to start and
operate normally. If operating the vehicle continuously for an extended
period (such as a long drive), the vehicle’s charging system should
charge the battery back to normal during that period. If the vehicle will
only be operated for a short period (short drive), the battery might need
to be charged again before it could start the vehicle again.
Completing an interrupted charge
•
– Once the battery has reached
85% charge; if the charging process is interrupted and restarted, the
charger could go straight into Maintain Mode. However, if the original
charge was started using the 10A rate, the charge can often be com-
pleted using the 2A rate.
CALCULATING CHARGE TIME
13.
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.
