Agm Battery Charging - Deeply Discharged (Below 3 Volts); Agm Low Maintenance Battery Testing - Polaris RANGER 1000 2020 Service Manual

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.

AGM LOW MAINTENANCE BATTERY
TESTING
Test the battery using the PU-50296 battery tester. If the
test fails, fully charge the battery.
If the battery is too low to accept a charge, see AGM
Battery Charging - Deeply Discharged (Below 3 Volts)
page 12.39.
If the tester indicates a test result other than "Good
Battery," follow the steps below before replacing the
battery:
1. Connect battery to the recommended battery charger.
2. If charging sequence does not initialize, refer to AGM
3. Re-test battery. If the test results show that battery
