Battery Charging - Polaris 2005 Sportsman MV7 Service Manual

New Batteries: Batteries must be fully charged
before use or battery life can be reduced by
10-30% of full potential. Charge battery for 3- -5
hours using a variable rate charger. Do not use
the alternator to charge a new battery. A high rate
battery charger can cause battery damage.
Low Maintenance batteries are permanently
sealed at the time of manufacture. The use of
lead- -calcium and AGM technology instead of
lead- -antimony allows the battery acid to be fully
absorbed. For this reason, a Low Maintenance
battery case is dark and the cell caps are not
removable, since there is no need to check
electrolyte level.
NEVER attempt to add electrolyte or water to a Low
Maintenance battery. Doing so will damage the
case and shorten the life of the battery. Refer to the
Battery Activation and Maintenance Video (PN
9917987) for proper instruction on servicing Low
Maintenance batteries.
NOTE: New Batteries: Batteries must be fully
charged before use or battery life will be reduced
by 10-30% of full potential. Charge battery for 3- -5
hours at a current equivalent of 1/10 of the
battery's rated amp/hour capacity. Do not use the
alternator to charge a new battery. (Refer to Battery
Activation and Maintenance video PN 9917987)
NEVER attempt to add electrolyte or water to a Low
Maintenance battery. Doing so will damage the
case and shorten the life of the battery. Refer to the
Battery Maintenance Video (PN 9917987) for proper
instruction on servicing
batteries.
Low Maintenance
To service a Low Maintenance battery:
1. Remove battery from the vehicle
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 capacity table.
3. Charge battery using a variable rate charger.
LOW MAINTENANCE

BATTERY CHARGING

If battery voltage is 12.8 V or less, the battery may
need recharging. When using an automatic charger,
refer to the charger manufacturer's instructions for
recharging. When using a constant current charger,
use the following guidelines for recharging.
NOTE: Always verify battery condition before and 1-2
hours after the end of charging.
WARNING: An overheated battery could 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.
