SECTION 4 ELECTRIC SYSTEM
SU5 OWNERS MANUAL 2014
Recharge batteries as soon as they become 20% or more discharged (less than 1.238 sp.
gr.).
Make it a regular habit to plug in the charger when the vehicle is not in use. Batteries may
be recharged if vehicle has been driven 15 minutes or more since the previous charge.
Make sure your electrical outlet is operational.
Never go below 20% state of charge (or 80% discharged) without recharging immediately.
Allow 14
– 16 hours of charging.
Batteries will provide a longer life if not deeply discharged. Batteries that are regularly
deeply discharged will require more work by the charger and will have a shorter life.
For non-sealed batteries, make it a regular habit to check (and water) your batteries after
charging. Always add water after charging. This will reduce the chance for overflow due to
expanding water.
Weekly equalize the battery pack.
If the vehicle is not operated daily the Power keyswitch should be turned off. This will power
down the traction control system and reduces power loss on the batteries.
Batteries in storage may self discharge and should be recharged when the specific gravity
falls below 1.238 sp. gr. or individual battery voltage is less than 5.25 volts for three cells
(10.5 volts for six cells).
BATTERY REMOVAL & INSTALLATION
Remove battery negative (-) cables and then battery positive (+) cables.
Remove battery hold down.
Remove batteries from vehicle.
To install batteries, reverse the removal procedure with the negative (-) cables being
attached last. Torque connections to 100 in. lbs.
SINGLE POINT BATTERY WATERING SYSTEM (If equipped)
NOTICE
: The following information does NOT apply to sealed batteries
This is a single point watering system for maintaining a sufficient electrolyte level in the
batteries.
NOTICE:
Do not operate this system on brand new batteries. See
SECTION 3
OPERATIONS AND CONTROLS,
IMPORTANT FIRST STEP for the initial check on the
electrolyte level of new batteries. Complete 4 to 5 charge cycles before using the
system.
System is to be used only after fully charging the batteries and batteries are warm.
The fill tube assembly which is used for adding water to the battery pack consists of a fill tube,
one end having a filter screen, the other having a female coupler and a rubber squeeze bulb.
Check the battery pack water level weekly by:
Inserting the fill tube filter end in an approved water supply.
Attaching the female coupler to the battery pack male coupler. Squeeze the rubber ball until
firm which indicates that filling is complete. Immediately disconnect the couplers by
depressing the push button on the female coupler. If the water supply is left connected after
the filling process is finished it could lead to an overfill.
