d.
Operate the power chair at high speed by
operating the joystick in a high-speed pro
fi
le. The
motors put approximately a 5 to 10 amp load on
the batteries.
e.
Continue to operate the motors for 60
seconds. (
fi
g. 5.21) Record the readings and
compare them to following:
i. During the
fi
rst 5 seconds, normal voltage
drop is approximately .5 to .6 VDC.
ii. During the remaining portion of the 60
seconds, the voltage should stabilize, dropping
no more than an additional .1 to .2 VDC.
iii. At the end of the 60 seconds, release the
joystick.
f.
At the end of a 5 minute rest, note the
voltage recorded on the Multimeter. Normal
indication at the end of a 5 minute rest is typically
the starting voltage, or no more than .1 VDC
less.

Notes:
•
A rapid drop of approximately 1.5 or more during the fi rst 5 seconds indicates a shorted
cell in one or both of the batteries. The battery terminals should be checked to ensure that they
are tight and clean, and then the test should be repeated. If the terminals are tight, the batteries
should be replaced. Refer to Battery Removal section of this manual.
•
A slow drop of more than .8 volts during the fi rst few seconds indicates a weakened pair
of batteries. Evaluate the age of the batteries and the use they have received, and consider
replacing them.
•
If the voltage does not return to .1 VDC of the starting voltage at the end of the 5 minute
test, evaluate the age of the batteries and the use they have received, and consider replacing
them.
