Fully charge both the new battery, and the
remaining original batteries. (specific gravity =
1.265 minimum, use a hydrometer)
Use a replacement battery that is close to the
same age as the remaining original ones.
Do not run the machine as long for about 20
cycles. For example, if you used to get 4 hrs
runtime, only run it for 2.5 hrs, and then charge
the batteries completely.
Opportunity charge. Equalize after 30 days.
The above steps will provide the best opportunity
for the new battery(s) to join the pack.
ACTIVATION OF DRY CHARGED
BATTERIES
NSS supplies some batteries in a “dry charged”
condition without any acid (electrolyte) in the battery.
The batteries cannot be used in this condition; they
must be activated by the addition of the battery acid
(electrolyte). Failure to follow this procedure will cause
severe damage to the batteries.
Materials Required
1.265 Specific Gravity, Sulfuric Acid, to fill batteries.
Rubber gloves and safety eye protection handling
Sulfuric acid.
Plastic funnel to pour Sulfuric acid into batteries.
Adjustable wrench and pliers to install battery cables.
Filling Procedure
Remove the cap from each cell of the batteries.
Fill each cell with Sulfuric acid fully to the bottom of
the access hole.
Allow the batteries to absorb the acid for a period of
one hour. During this time the acid level in each cell
will drop and the batteries will become warm.
Refill each cell with Sulfuric acid to a point 1/4” (6mm)
below the bottom of the access hole.
Replace the cap in each cell of the batteries.
Neutralize any spilled acid with bicarbonate of soda.
Rinse the battery case clean with clean water and dry
the battery case.
Batteries are heavy - use two people to install.
Refer to wiring diagram inside the battery
compartment. Align batteries in compartment as
shown on diagram.
Install battery cables as shown on wiring diagram
Tighten bolts and hex nuts with a wrench.
Caution
: Do not short across two terminals with a
wrench.
Loose or improper battery connections will cause
battery or machine damage and possible personal
injury.
Connect the charger to the machine and allow it to
perform one complete charging cycle, (8 – 12 hours).
Liquid level adjustment during the life of the batteries
should be made with distilled water.
If dry charged batteries have been filled with acid
(electrolyte) and are placed in storage, the batteries
must be recharged every 30 days to prevent damage.
BATTERY AUTO-FILL INSTRUCTIONS
WARNING:
When working with Lead-Acid batteries
and Battery Acid observe all battery manufacturers’
safety precautions.
Caution:
This option is not for well or tap water.
Connect the regulated hose system to water supply.
Aim the purge into drain or bucket and turn on water
supply. When air is removed from the system
disconnect quick coupler by pushing the button
labeled CPC.
Check the system for leaks by connecting the
regulated hose system quick connect to the Auto-Fill
quick connect. After connection the red balls in the
flow indicator will spin indicating water flow. When
the balls stop spinning check the system for leaks and
IMMEDIATELY
disconnect the quick coupler.
Place the dust cover over the male quick coupler on
the Auto Fill system. Turn off water supply and
remove the regulated hose system. Reinstall the
purge quick coupler and store in a safe place.
We recommend you remove the hose swivel and
valve from one cell to check the electrolyte level after
the first fill.
Battery Charger
The onboard battery charger supplied with this machine
is capable of charging lead acid batteries from 185 to
350ah capacity. There is no need to change algorithms
or settings based on battery manufacturer, or battery
size.
The charger can also be set to charge flooded (wet)
cell, AGM, or Gel batteries. LED’s on the charger
indicate which type of battery the charger is set to
charge. One setting is for Flooded and (most) AGM
batteries, the other setting is only for Crown and Trojan
AGM and GEL batteries.
Depending on the battery charger model, the charger
can operate on 100/115/230 VAC 1ph 50/60 HZ power,
and will automatically detect these input voltages.
Before connecting the battery charger to power, check
the label on the battery charger to verify the proper
input power.
Determining Your Battery Type
CAUTION: DIFFERENT BATTERY TYPES HAVE
DIFFERENT CHARGING REQUIREMENTS. FAILURE
TO PROPERLY IDENTIFY YOUR BATTERY TYPE
AND SET THE CHARGER ACCORDINGLY WILL
RESULT IN BATTERY DAMAGE, AND VOID THE
WARRANTY.
Your machine may have been ordered with batteries
installed at the NSS factory. The standard battery type,
normally supplied by NSS, is the flooded (wet) cell lead
acid battery. Gel and AGM sealed batteries may also
be available at customer request.
