Using Your Battery Charger
To obtain the best results from your battery charger, you must know how to use it properly. This section will tell
you how to set the controls, and how you can charge a battery while it is still in the vehicle, or you can remove it
and then charge it. Follow the instructions below depending on how you choose to charge your battery.
Setting the controls
All the controls for your charger are located on the
front of the unit. Follow these instructions to obtain the
accurate charge level for your battery,
VOLT/AMP SELECTOR:
Use the VOLT/AMP SELECTOR switch to select an
amp charge rate and battery voltage type to match your
charging needs. Read the following operating
instructions for making the proper settings for charging a
battery and using the ENGINE START feature.
TIMER:
The timer is designed to allow your battery to be charged
for a designated amount of time. To accurately charge
your battery, you must know the size of the battery in
ampere hours or reserve capacity in minutes, as well as
the state of charge. Since this information is often not
known, the timer limit is set at 2.25 hours. This will help
prevent the battery from overcharging to a point where it
can be damaged. If you do not know the charge state of
your battery, it is best to start out with the timer set at
one hour or less.
HOLD feature;
This position overrides the timer — the charger will
continue charging until the operator stops the
charging process. When using HOLD, you must
monitor the charging and turn the charger OFF
when the battery is fully charged. OVERCHARGING
may damage your battery.
AMMETER:
The AMMETER indicates the measured amount of
amperes being drawn by the battery. When you first
start charging a battery, the reading will be high:
• The needle will be around 60 when the selector is in
the 60 amp charge position. As the battery becomes
charged, the reading will decrease to 25 or 30 amps
at full charge. This will be your indicator to stop
charging.
• With the selector switch set to the 20 amp position,
the meter should display 20 amps for a discharged
battery and 8 to 10 amps when the battery is fully
charged.
• At the 2 amp charging rate, you may see no needle
activity.
