Choosing the Operating Voltage and a Charging Rate
Always set the Operating Voltage for any function to match the voltage of the battery/system to which the charger
is connected. If the battery voltage is not clearly marked on the battery, refer to the operator's manual for the
vehicle/equipment where the battery is used/intended to be used. NEVER begin charging if the battery voltage
cannot be determined.
Choose a charging rate that is appropriate for the size and type of battery being charged. Use the battery
manufacturer's specific instructions or see the guidelines below.
Typical rates are:
Small Motorcycle/Powersport
Lawn Mower/Tractor
Deep Cycle
Maintenance Free Automotive or Marine Cranking
Heavy Duty Commercial
Do not exceed the maximum charge rate recommended by the battery manufacturer or the chart above.
Unless the information is supplied for the particular battery, always charge small batteries at no more than 5 Amps.
If the battery requires charging at less than 5 Amps, do not attempt to charge such batteries using this charger.
Choosing a Battery Type Setting
PRO-LOGIX Wheel Charger models utilize advanced charging technology to deliver precise charge controls,
enabling them to properly charge a wide variety of battery types.
• For Conventional and Maintenance Free Flooded (wet) Cell batteries: Choose STANDARD.
• For AGM batteries: Choose AGM.
• For Spiral Wound Batteries: Choose AGM.
• For Gel Cell batteries: Choose GEL.
For batteries identified as Deep Cycle or Marine batteries, determine the construction of the battery. Is it a wet cell,
AGM, Spiral or Gel Cell type of construction? Battery construction will determine the proper battery type selection.
Pre-Charge Battery Activation
Some modern batteries can cause charging problems if they have been deeply discharged. The plates in these
batteries can begin sulfating quickly, forming a barrier to accepting a charge. This condition will be indicated
by an extremely low (or zero) ammeter reading, indicating that the battery is not accepting current from the
charger. A deeply discharged battery such as this may take as long as 4 to 8 hours before it will accept a charge.
The Automatic Charging mode attempts to detect batteries with this condition (see Battery Repair Mode in
PREPARATION) and automatically adjusts for it.
If you prefer to activate the battery manually, follow this procedure:
Function Select Manual Charge Mode
Specify the correct battery voltage (6/12/24V)
Specify a moderate charge rate (such as 5A or 15A).
Monitor the battery every 30 minutes. When the sulfate barrier has been broken through, the battery will begin
accepting a charge and the ammeter current will be at the 5A or 15A selected rate. The amount of time to charge
the battery fully (determined in Charging Time Instructions) begins when the battery begins accepting a charge.
Once the battery begins to accept a charge, you may return to Auto Mode charging to safely charge
your battery.
