7 BATTERIES

7.3 BATTERY SYSTEMS _______________________________________________________
The Eclipse mower is available with either a battery
power module, a gas engine hybrid power module, or a
diesel engine hybrid power module.
1. The battery powered Eclipse has six, 8 VDC
batteries wired in series. Batteries must be
disconnected from the mower for charging.
2. The gas and diesel hybrid powered mowers contain
two separate battery systems.
a. A 48 VDC buffer battery pack, comprised of four
12VDC batteries wired in series. The buffer
batteries are charged by the hybrid generator
during operation. See Section 7.8 for charging
buffer batteries using an external charger.
b. A 12 VDC battery for engine operation.
7.4 BATTERY FILLING (BATTERY POWERED MOWERS)____________________________
When the batteries require additional water, distilled
water is recommended (never use water with high
mineral content).
The Eclipse mower with battery power module is
equipped with a battery filling system. Water should be
added AFTER the batteries have been charged so that it
will not overflow during charging.
However, batteries should NOT be charged if the
electrolyte level is below the top of the plates. If the level
has been allowed to go below the top of the plates, add
just enough water to cover the plates before charging.
Then after charging, check the level again, and add water
as required to bring it to the proper level.
To fill batteries using the battery filling system:
1. Fully charge the battery pack.
2. Fill battery filling system tank with distilled water.
Support tank at least 36 in. (1 meter) above
batteries.
3. Locate filling system connector on right side of
battery tray and connect to tank hose.
4. Flow indicator will start spinning and distilled water
will flow down to any batteries that require additional
water. Each battery connection has a float to
prevent over filling.
5. Observe flow indicator on tank hose. Keep tank
connected to batteries until flow indicator stops
spinning. Disconnect hose and store tank in secure
location for future use. Do not operate mower with
tank connected to batteries.
6. Periodically spot check the electrolyte level in the
cells. Excessive water consumption indicates one or
all of the following:
a. Overcharging.
b. High temperature operation.
c. The battery is nearing the end of its service life.
NOTICE
The buffer batteries can be charged using the same
battery charger that is used on battery power
modules. The charger is not included with hybrid
power modules and must be ordered separately.
CAUTION
Battery electrolyte is an acidic solution and should be
handled with care. If electrolyte is splashed on any
part of the body, immediately flush the exposed area
with liberal amounts of water, and obtain medical aid
immediately.
NOTICE
The 12 VDC batteries used on hybrid powered
mowers are sealed and do not require filling.
