MAINTENANCE

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. See page 80.
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 page 85 for the part numbers
of POLARIS products.

A poorly maintained battery will deteriorate rapidly. Check the

harmful to a battery.
