SPECIFIC WET CELL BATTERY INFORMATION
Wet Cell Battery speci fi cations
- Use a combination of multiple 2-volt cell units to construct a 36 Volt DC battery pack system.
- Advance recommended battery pack capacity is a 305 AH @ 20 Hour Rate deep cycle battery system.
Note: The battery pack must fi t the battery compartment
size listed in Speci fi cations .
Wet Cell Battery Charger Speci fi cations
- Use a 36 Volt DC output charger matching the DC battery pack voltage and the input AC line voltage supply being used.
- When selecting a battery charger always 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 305 AH battery should be matched to a 36V, 20-25 Amp output charger on machines using (6) 6V batteries.
DESCRIPTION OF THE LOW-VOLTAGE CUTOUT FEATURE
All models discussed in this manual are equipped with a low-voltage cutout feature to prevent over-discharging of the batteries. When a machine’s battery pack
voltage falls below speci
fi cally de fi ned thresholds (voltage settings) the scrub system is automatically shut down. The cutout level is adjustable. The standard lead
acid battery (wet cell) setting is 1.72V per cell and alternate maintenance free battery (gel cell) setting is 1.81V per cell. The standard setting is factory selected and
should be used unless the battery manufacturer speci
fi es the higher cutout voltage.
Special Service Note: On all the 36V machines a minimum recharge voltage of 2.13 volts per cell must be reached to allow the scrub brush and solution system to
(reset) function again. A 36V-battery pack must increase to a 38.6-volt minimum.
DESCRIPTION OF THE BATTERY CONDITION INDICATORS
The Battery Condition Indicator will give an indication of the state of charge of the batteries, 5 vertical bars (or a green light) indicates a fully charged battery after a
complete charging cycle. The battery condition indicator will retain the state-of-charge even if the key has been turned off. The state-of-charge indication is reset to
full charge when the batteries have been recharged. It is also possible to choose between two different low-voltage thresholds depending on whether maintenance
free or standard batteries are being used
(have quali fi ed service engineer perform this selection*) . Note: The following percentages are based on useable
battery capacity not total battery capacity. Therefore, 100% discharge = 80% of total battery capacity for standard wet cell batteries or 70% of total battery capacity
for maintenance free batteries.
