Battery Maintenance and Charging
WARNING
An overheated lithium ion battery may overheat,
catch fire, or 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.
Battery Storage
If storing your generator for an extended amount of time, Polaris recommends starting the generator once a month to charge the battery. Use the table below to determine how long the generator must run to fully charge the battery depending on the battery’s current state of charge. Always verify battery condition before and 1-2 hours after charge completion. Store the generator and battery in a cool, dry place.
