6. Install clear battery vent tube from vehicle to battery vent.
7. Route cables so they are tucked away in front and behind
battery.
Low Maintenance Battery Check:
NOTE: All Low Maintenance batteries are fully
charged and tested at the factory before installation.
Expected shelf life varies on storage conditions. As
a general rule before placing the battery into service,
check the battery condition and charge accordingly.
1. Check the date label on the side of the battery to calculate
when to check voltage. The battery should be checked
every 3 months.
2. Check the voltage with a voltmeter or multimeter. A fully
charged battery should be 12.8 V or higher.
3. If the voltage is below 12.8 V, the battery will need to be
recharged.
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 Low
Maintenance batteries.
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
Vent tube must be free from obstructions and kinks
and securely installed. If not, battery gases could
accumulate and cause an explosion. Vent should
be routed away from frame and body to prevent
contact with electrolyte. Avoid skin contact with
electrolyte, as severe burns could result. If
electrolyte contacts the vehicle frame, corrosion will
occur.
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.
