Sealed/AGM Battery Maintenance and Charging
Sealed batteries are already filled with electrolyte and have been sealed and fully charged at the factory.
Never pry the sealing strip off or add any other fluid to a sealed battery.
Battery Charging
For a refresh charge, follow all instructions carefully.
-
Check the battery voltage with a voltmeter or multimeter. A fully charged battery will register 12.8 V or higher.
-
If the voltage is less than 12.8 volts, recharge the battery at 1.2 amps or less until battery voltage is 12.8 or greater.
-
If the voltage falls below 12.5V, charge it immediately, or the battery runs the risk of sulfation and reduced battery life.
The single most important thing about maintaining a sealed battery is to keep it fully charged.
If you do not drive the vehicle for more than TWO WEEKS, Polaris recommends using a BatteryMINDer® 1510 - 1.5 AMP charger (PN 2830404), which can be ordered through your dealer. During charging, place the charger outside of the vehicle and protect it from moisture. The battery charge port 1 is located on the dash.
Battery Storage
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® 1510 - 1.5 AMP charger.
When using an automatic charger other than a BatteryMINDer® 1510 - 1.5 AMP charger, refer to the charger manufacturer's instructions for recharging.
If using a constant current charger (instead of BatteryMINDer® 1510 - 1.5 AMP charger), use the guidelines below. Always verify battery condition before and 1-2 hours after the end of charging.
State of Charge | Voltage (DC) | Action | Charge Time* |
100% | 12.8-13.0 volts | None, check monthly | None required |
75%-100% | 12.6-12.8 volts | May need slight charge, if no charge given, check in 2 weeks | 3-6 hours |
50%-75% | 12.3-12.6 volts | Needs charge | 5-11 hours |
25%-50% | 12.0-12.3 volts | Needs charge | At least 13 hours |
0%-25% | 12.0 volts or less | Needs charge | At least 20 hours |
* Using AGM specific charger at standard amps specified on top of battery |
