Caring for the Lithium Ion
Battery Pack
WARNING
The battery pack contains high voltage, which
could burn or electrocute you.
• Never attempt to open the battery pack.
• Do not place anything in the connector on
the battery pack other than the wire harness
connector that came with the product.
• Use extreme care when handling a battery pack
with a cracked case.
• Use only the charger designed for the battery
pack.
Charging the Battery Pack
Charge the battery pack when you are finished mowing for
the day to ensure that it is fully charged for the next day's
mowing. Unlike other battery types, lithium ion batteries do
not have a charge memory issue and do not need to be fully
discharged before charging them.
Refer to the Lithium Ion Battery Charger Operator's Manual for
detailed instructions on charging the battery pack.
If you will be storing the mower for more than 10 days, ensure
that you place it on the charger and leave the charger turned
on. After 10 days of inactivity, the charger automatically
switches to storage mode, during which it reduces and
maintains the charge to 40% of maximum. Refer to
(page 41)
for more information on storing the machine and
for removing the battery from storage mode.
Transporting the Battery Pack
The US Department of Transportation and international
transportation authorities require that lithium ion batteries be
transported using special packaging and only be transported
by carriers certified to haul them. In the US, you are
allowed to transport the battery when it is installed on the
machine as battery powered equipment, with some regulatory
requirements. Contact the US Department of Transportation
or the appropriate government body in your country for
detailed regulations on transportation of your eFlex or eFlex
battery.
For detailed information on shipping the battery pack, refer
to the instructions (3373-934) included with the Battery
Shipping Kit (Model 120-4600). These instructions are
available for download from www.Toro.com.
Caring for the Battery Pack
As with all rechargeable batteries, lithium ion batteries have
a life span during which they hold a sufficient charge to
perform the work for which they are intended. As time goes
by, the total amount of work the battery is able to complete
on a single charge gradually diminishes. The following table
lists the approximate expected work that the machine should
be capable of over the first 5 years of use:

Note: Your results may vary depending on the distance you
need to transport the machine, the contact setting of the bed
knife, and other factors as discussed in this section.
To achieve maximum life and use from your battery, apply
the following care guidelines:
•
Do not open the battery pack. There are no user
serviceable parts inside. If you open the pack you will void
your warranty. The pack is protected by tamper-alerting
devices.
•
Store/park the machine in a clean, dry garage or storage
area, away from direct sunlight and heat sources. Do
not store it in a location where the temperature drops
below -13 degrees F (-25 degrees C) or rises above 113
degrees F (45 degrees C). Temperatures outside of this
range will damage your battery. High temperatures
Storage
during storage, especially at a high state of charge, reduces
the life of the batteries.
•
When storing for more than 10 days, ensure that the
machine is in a cool location, out of sunlight, and
connected to the charger.
•
If you are mowing in hot conditions or in sunlight, the
battery may overheat. If this happens, a high-temperature
alert will appear on the InfoCenter LCD display. In this
condition, the machine no longer operates with the reel
engaged and the machine slows down.
Immediately drive the machine to a cool location out of
the sun, turn off the machine, and allow the battery to
cool fully before resuming operation.
•
Keep the battery pack cover clean. The white color
reflects sunlight and slows the heat buildup in the battery
pack. A dirty cover increases the heat in the battery pack
each day and reduces the energy capacity.
•
Adjust the bed knife to reel contact to be as light as
possible. This reduces the power needed to run the reel
and increases the amount of work the machine performs
on each charge.
