Battery Storage
Requirements
Note:
You do not need to remove the batteries from
the machine for storage.
Refer to the temperature requirements for storage in
the following table:
Temperature Requirements for Storage
Storage Conditions
Normal storage conditions
Extreme heat—1 month or
less
Important:
Temperatures outside of this range
will damage your batteries.
The temperature that the batteries are stored
at will affect their long-term life. Storage for
long periods of time at extreme temperatures
will reduce the battery life. Store the machine in
the normal storage conditions indicated in the
temperature-requirements table.
•
Before you store the machine, charge or discharge
the batteries between 40% to 60% (54.3V to
57.3V).
Note:
A 50% charge is optimal to ensure a
maximum battery life. When the batteries are
charged to 100% before storage, the battery life
shortens.
If you anticipate that the machine will be stored
for a longer period of time, charge the batteries
to around 60%.
•
For every 6 months of storage, check the
battery-charge level and ensure that it is between
40% to 60%. If the charge is below 40%, charge
the batteries between 40% to 60%.
•
You can use a multimeter to check the charge level
when the machine is off. Refer to the following
table for the amount of voltage that is equal to the
charge level:
Voltage
57.3V
55.4V
54.3V
•
After charging the batteries, disconnect the
battery charger from power. Disconnect the
power connector during storage to minimize the
discharging of the batteries.
•
If you leave the charger on the machine, it will
shut off after the batteries are fully charged and
does not turn back on unless the charger is
disconnected and reconnected.
Temperature Requirement
-20° to 25°C (-12° to 77°F)
25° to 55°C (77° to 131°F)
Charge Level
60%
50%
40%
Storing the Charger
1.
Disconnect the power to the machine; refer to
Using the Battery-Disconnect Switch (page
2.
Disconnect the power supply cord from the
charger and coil it securely.
3.
Examine the power supply cord thoroughly for
signs of wear or damage. Replace it if it is worn
or damaged.
4.
Examine the charger thoroughly for worn, loose,
or damaged parts. To repair or replace parts,
contact your authorized Toro distributor for
assistance.
5.
Store the charger with the power supply cord in
a clean, dry place where it will not be bumped or
damaged and not exposed to caustic fumes.
