BATTERY STORAGE
Whenever the vehicle is not used for a period of three months or more, remove
the battery from the vehicle, ensure that it's fully charged, and store it out of the
sun in a cool, dry place. Check battery voltage each month during storage and
recharge as needed to maintain a full charge.
POLARIS recommends maintaining battery charge by using a POLARIS Battery
Tender charger or by charging about once a month to make up for normal self-
discharge. Battery Tender can be left connected during the storage period, and
will automatically charge the battery if the voltage drops below a pre-determined
point. See the Polaris Products section for the part numbers.
BATTERY CHARGING
The following battery charging instructions apply only to the installation of a
sealed battery. Read all instructions before proceeding with the installation of
this battery.
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. Since the battery is sealed and the sealing strip cannot be
removed, you must use a voltmeter or multimeter to measure DC voltage.
WARNING
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.
For a refresh charge, follow all instructions carefully.
1. The battery should be disconnected from a load or charger for at least two
hours before checking voltage. Check the battery voltage with a voltmeter or
multimeter. A fully charged battery will register 12.8 V or higher.
2. 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.
3. When using an automatic charger, refer to the charger manufacturer's
instructions for recharging. When using a constant current charger, use the
following guidelines via the table below.
BATTERY CHARGING (SEALED BATTERY)
Always verify battery condition before and 1-2 hours after the end of charging.
