charger is operating properly, then the
battery pack capacity is most likely low.
Note: Batteries that have lost
capacity will usually still have the
same power they had previously.
For this reason the range of the
FunRunner will be reduced, but the
performance of the vehicle while
driving after a charge will be normal.
A vehicle that is charged completely
and performs well but has a reduced
range will more then likely have a
reduced capacity battery pack.
Some operators that only drive short
distances between charges will not
notice a loss of capacity until it
reaches a point that it will no longer
cover the needed distance on one
charge.
Full Test
•
Batteries should have 50% or more
charge.
•
Remove rear body panel.
•
Perform visual inspection.
•
Connect a voltmeter to each module.
See Figure 5-20.
•
Drive vehicle until battery state of
charge is at approximately ½ charge.
•
Power test - During a hard pull at wide-
open throttle up a hill if possible for
about 10 seconds, observe the
voltages. All modules should maintain
a minimum of 9 volts.
•
Continue to drive the vehicle until the
state of charge gauge drops to ¼
charge.
•
Capacity test – Drive steady at a
moderate speed for about 30 seconds
while monitoring the module voltages.
All module voltages should remain
within 0.5 volts of each other.
•
Replace all modules if any failed the
power or capacity test. If all modules
have tested ok, the pack is balanced
and need not be replaced unless the
pack capacity will not deliver a suitable
range.
•
Leave voltmeters connected and plug
charger cord in to charge the batteries.
•
Monitor the module voltages at various
times during charging. Keep in mind
that a charge will last 7-8 hours.
Voltages should remain within 0.5 volts
of each other until the end of charge
where they should all become almost
equal. If new battery modules were
installed, leave charger on overnight.
The extended float charge will help
balance the pack.
