Polaris MS4000 Service And Owner's Manual page 23

The deep cycle battery is located under the driver. Its size is considered a group 27. When
replacing this battery always replace it with a Group 27 Deep Cycle battery.
This battery needs to be charged daily to prevent discharge.
If the deep cycle battery gets discharged completely (less than 2 volts), the onboard battery
charger will not start charging the battery.
You will need to hook up an external battery charger like one you would put on your car or attach
a pair of jumper cables from another vehicle for a couple of minutes.
If using an external charger it will need to be used for approximately one half hour. This will put
enough charge into the battery to allow the onboard charger to start charging the battery.
Note: The onboard battery charger will not start charging a battery that is completely
dead. The charger thinks that that battery may have a shorted cell in it and prevents the
charging process from starting for safety reasons.
Start Charging the Batteries
To start charging the batteries you can do it one of two ways. You can simply plug in an
extension cord into the shoreline receptacle located near the driver's door. Or you can start the
generator. After you do one or the other, locate the onboard battery charger. It will be located
under the dash on earlier models and under the hood on newer models.
Observe the red L.E.D bar graph. The more red lights you have the more the battery is
discharged. As the battery charges up the lights will one by one go out resulting in just one red
light. It then will turn green, indicating the battery is fully charged. The charger has two indivual
battery chargers within the one case, so they are completely separate from each other. So you may
have one green light on one battery and red lights showing on the other battery.
