General Battery Information
IMPORTANT: Never attempt to add electrolyte or
distilled water to a Maintenance Free battery. Doing so
will damage the case and shorten the life of the
battery.
1. Check battery voltage with a volt/ohm meter. A fully
charged battery should be 12.8 V or higher.
2. If the voltage is below 12.6 V, the battery will need to be
recharged (see “Charging Procedure”).
To service a Maintenance Free battery:
1. Remove battery from the vehicle (see Chapter 2).
2. Test battery with a voltage meter or load tester to determine
battery condition. This will determine the length of time
required to charge the battery to full capacity. Refer to OCV
table (see “OCV - Open Circuit Voltage Test”).
3. Charge the battery as recommended (see “Charging
Procedure”).
Battery Removal / Installation
See Chapter 2 “Maintenance” for battery removal and
installation procedures.
Battery Off Season 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.
NOTE: Battery charge can be maintained by using a
Polaris battery tender charger or by charging once a
month to make up for normal self-discharge. Battery
tenders can be left connected during the storage
period, and will automatically charge the battery if
the voltage drops below a pre-determined point.
Battery Testing
Whenever a service complaint is related to either the starting or
charging systems, the battery should be checked first.
Following are two tests which can easily be made on a sealed
Maintenance Free battery to determine its condition: OCV Test
and a Load Test.

CALIFORNIA PROPOSITION 65 WARNING:
Batteries, battery posts, terminals and related
accessories contain lead and lead compounds, and
other chemicals known to the State of California to
cause cancer and birth defects or other reproductive
harm. WASH HANDS AFTER HANDLING.
Battery electrolyte is poisonous. It contains acid!
Serious burns can result from contact with the skin,
eyes, or clothing.
ANTIDOTE:
External: Flush with water.
Internal: Drink large quantities of water or milk. Follow
with milk of magnesia, beaten egg, or vegetable oil.
Call a physician immediately.
Eyes: Flush with water for 15 minutes and get prompt
medical attention.
Batteries produce explosive gases. Keep sparks,
flame, cigarettes, etc. away. Ventilate when charging
or using in closed space. Always shield eyes when
working near batteries.
Keep out of reach of children.
