Battery Storage; Battery Charging - Polaris RANGER Diesel 2013 Owner's Manual For Maintenance And Safety

MAINTENANCE
Battery

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 page 80 for the part num-
bers of POLARIS products.

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 bat-
tery 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.
Always keep a sealed battery 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. 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 guidelines below for recharg-
ing.
Always verify battery condition before and 1-2 hours after the end of charging.
