CHARGING
Polaris recommends using the BatteryMINDer® 2012
AGM - 2 AMP battery charger to charge and maintain
Absorbent Glass Mat (AGM) batteries. The charger can
be ordered through your normal parts channel.
BatteryMINDer® 2012 AGM - 2 AMP battery charger

Nominal voltage is 12.8 Volts when fully charged. If the
voltage falls below 12.5V, charge it immediately, or the
battery runs the risk of sulfation.
AGM chargers are designed specifically for charging
AGM type batteries and use high frequency pulses to
partially reverse sulfation.
IMPORTANT
The use of non-AGM battery chargers or non-AGM
battery tenders may result in a misleading “battery not
found” or “open cell” fault message. Please ensure you
are using the recommended AGM charger when
charging AGM type batteries.
AGM BATTERY CHARGING - LOW CHARGE
The nominal voltage for an AGM battery is 12.8 Volts
when fully charged. The battery will self-discharge when
disconnected from a vehicle, and will discharge at a
faster rate when connected. If the battery voltage falls
below 12.5V, it should be charged immediately using the
recommended battery charger. Listed below are the
recommended battery inspection schedules.
• Batteries which are not connected to a vehicle should
be inspected every 60 days. The battery must be
charged if found to be below 12.5 volts.
• Batteries which are connected to a vehicle should be
inspected when they arrive at your dealership and at
least once every month thereafter. The battery must be
charged if found to be below 12.5 volts.
• Showroom vehicles used to demonstrate radio, display
and infotainment features should be charged daily. If
possible, these vehicles should be connected to the
recommended battery charger continuously.
IMPORTANT
Always use the recommended automatic battery
charger, and wait for the charger to complete the
charge cycle before disconnecting it.
AGM BATTERY CHARGING - DEEPLY DIS-
CHARGED (BELOW 3 VOLTS)
AGM batteries discharged to a voltage of 3 volts or less
may not be recognized by the recommended automatic
battery charger. (The minimum voltage threshold
recognized by other battery chargers may be as high as
10.5 volts). Often times deeply discharged batteries can
be restored by attaching another, fully-charged, battery
to “jump start” the low battery. Follow the steps below to
restore a deeply discharged battery.
1. Carefully connect the two batteries’ positive
terminals, then the negative terminals using jumper
cables.
2. Connect the recommended battery charger to the low
battery and initiate the charging sequence.
WARNING
Always check to ensure the positive cables are
connected to the positive terminals before powering the
charger on. Reversing polarity when charging can
damage electrical components and risk personal injury.
Be careful not to let battery cable clamps touch each
other.
3. After the charging sequence has initiated, disconnect
the fully-charged battery. Always disconnect the fully-
charged battery positive first, followed by low battery
positive, low battery negative, and finally fully-
charged battery negative.
4. Proceed with charging both batteries to full capacity.
Listed in the table below are the approximate
charging times for deeply discharged batteries.
Always use the recommended automatic battery
charger, and wait for the charger to complete the
charge cycle before disconnecting it. The
recommended automatic charger will indicate when
the battery is fully charged on its display.
