CHARGING THE BATTERIES (CONTINUED)
The following lights indicate the percentage of discharge in the battery pack:
Battery Voltage
Indication Standard Alternate
Green 33.5+ 33.7+
Green/Yellow 33.4 33.6
Yellow 32.8 33.4
Yellow/Red 31.9 33.2
Red 31.3 33
Red Flashing 30.6 32.8
BATTERY TESTING
A battery problem is usually recognized by the machine operator, as a decrease in the machine’s running time. This condition is usually caused
by one (or more) “dead cell” in the battery system- that is, one (or more) cell that is putting out less voltage than the other cells.
Note: Always charge batteries before testing.
There are 2 ways to fi nd a dead cell:
• Use a hydrometer to check the specifi c gravity (or “state of charge”) of the fl uid in each cell. A dead cell is one that reads 50 points (or more)
lower than the other cells.
• Use a voltmeter to check the voltage of each battery with the pad drive motor running. The battery with the dead cell will read 1 or 2 volts
lower than the other batteries in the system.
If the batteries in the machine are more than 1 year old, it’s usually best to replace the whole set, rather than replacing just one battery.
BATTERY SPECIFICATIONS
Use a combination of multiple 2-volt cell units to construct a 36 Volt DC battery pack system.
Nilfi sk-Advance recommended battery pack capacity is a 395 AH @ 20 Hour Rate deep cycle battery system. Note: The battery pack must fi t the
battery compartment size listed below.
Battery compartment size
Height 17-1/2 inches (44 cm)
Width 22-1/2 inches (57 cm)
Length 25 inches (63 cm)
BATTERY CHARGER SPECIFICATIONS
Use a 36 Volt DC output charger matching the AC input line voltage supply to be used.
Always when selecting a battery charger follow the recommendation of the battery supplier to match the proper charger DC output amperage to
the amp/hour rating batteries being installed. This will prevent the battery pack from being over or under charged.
The recommended 395 AH battery should be matched to a 36V, 25 or 36 Amp output charger.
