BATTERY MAINTENANCE AND CHARGING
An overheated battery may explode, causing severe injury or death. Always
watch charging times carefully. Stop charging if the battery becomes very
warm to the touch. Allow it to cool before resuming charging.
The sealed battery is already filled with electrolyte and has been sealed and fully
charged at the factory. Never pry the sealing strip off or add any other fluid to this
battery.
The single most important thing about maintaining a sealed battery is to keep it
fully charged. Check the battery voltage with a voltmeter or multimeter. A fully
charged battery will register 12.8 V or higher. If the voltage falls below 12.5V,
charge it immediately, or the battery runs the risk of sulfation and reduced
battery life.
If you do not drive the vehicle for more than TWO WEEKS, Polaris recommends
using a BatteryMINDer® 2012 AGM - 2 AMP charger (PN 2830438), which can
be ordered through your dealer.
Polaris provides a charging accessory with your vehicle that allows easy
connection to the battery through the 12V auxiliary outlet, located on the dash.
During charging, place the charger outside of the vehicle and protect it from
moisture.
The 12V socket located in the rear of 4 seat vehicles is powered after key-on
If you plan to store the vehicle for ONE MONTH or longer, remove the battery
from the vehicle, then store the battery in a cool and dry location. Continue to
maintain the battery with the BatteryMINDer® 2012 AGM - 2 AMP charger.
When using an automatic charger other than a BatteryMINDer® 2012-AGM - 2
AMP charger, refer to the charger manufacturer's instructions for recharging.
If using a constant current charger (instead of BatteryMINDer® 2012 AGM - 2
AMP charger), use the guidelines below. Always verify battery condition before
and 1-2 hours after the end of charging.
