Lithium Battery Pack Service
IMPORTANT: Do not open the lithium battery pack.
With the exception of the battery pack fuse, fuse
cover and labels, there are no consumer service-
able parts on or in the battery pack. If you open the
battery pack, you will void the warranty. The battery
pack is protected by tamper--alerting devices.
Lithium Battery Pack Care
When mowing, use the InfoCenter on your eFlex to
monitor the state of charge of the lithium battery pack.
Consistently operating the machine with a very low state
of charge willadversely affect the life of the battery pack.
If problems w ith the battery pack exist, an advisory or
fault may be identified on the InfoCenter display. Refer
to InfoCenter Display in this chapter for information on
advisories and f aults.
When finished with machine use for the day, park your
eFlex in a clean and dry garage or storage area that is
awayfrom direct sunlight and other heat sources. Do not
store the machine in a location where b attery pack tem-
perature could rise above 113
o
F(45
o
C).Ifthebatteryis
subjected regularly to excessive temperatures, the life
of the battery pack will be reduced.
Charge the battery pack when you are finished mowing
for the day to ensure that the battery is fully charged for
the next mowing. Lithium ion batteries do not have a
charge memory issue and do not need to be fully dis-
charged before charging them. Make sure that the bat-
tery pack is charged with the Toro lithium battery pack
charger that is specifically designed for the eFlex battery
pack. For best battery life, connect the battery pack to
the battery charger when the machine is not in use.
Keep the battery pack cover clean. A dirty cover will in-
crease the heat in the battery pack and will reduce the
energy capacity and life of the battery pack.
The eFlex lithium battery pack includes a fuseforbattery
circuit protection. For information on servicing the bat-
tery pack fuse, see Lithium Battery Pack Fuse in the
Component Testing section of this chapter.
If lithium battery pack service is required, contact your
Toro Distributor for assistance.
Lithium Battery Pack Storage
If the mower will be stored for more than ten (10) days,
ensure that the battery is connected to the lithium bat-
tery pack charger. If the battery pack is not c onnected to
the charger during storage, battery pack life will be re-
duced.
Do not store themachineina location where the temper-
ature will drop below --13
o
F(--25
o
C) or rise above 113
o
F
(45
o
C). Because storage temperature will affect the life
of the battery pack, avoid storing your eFlex in temperat-
ures outside of this range. Storage for long periods of
time at high temperatures will reduce the life of the bat-
tery pack, especially if the pack is stored with a high
charge. Where possible, store the machine in a cool (not
below freezing) location.
After ten (10) days, the charger will enter a storage
maintenance mode, adjusting the battery to a charge of
40% of maximum. This charge level during long term
storage will ensure the full life of the battery. If you do not
keep the battery pack connected to the charger during
storage, the high state of charge in the battery pack will
shorten thelife of the battery, especially if stored in warm
conditions.
Followprocedurein eFlex Operator’sManual for remov-
ing the machine from storage.
Lithium Battery Pack Shipping and Transporting
The US Department of Transportation and international
transportation authorities require that lithium ion batter-
ies be transported using special packaging and only be
transported by carriers certified to haul them. In the
USA, you are allowed to transport the battery when it is
installedonthemachineasbatterypoweredequipment,
with some regulatory requirements. Contact the US De-
partment of Transportation or the appropriate govern-
ment body in your country for detailed regulations on
transportation of your eFlex or eFlex battery.
The Toro Battery Shipping Kit includes instructions that
detail information on shipping the lithium battery pack.
Refer to Operator’s Manual for part number information.
These instructions are also available for download from
www.toro.com. Failure to ship the lithium battery pack
correctly can result in large f ines.
