Temperatures outside of these ranges 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. For
temperatures above 25°C (77°F), only store the machine for the appropriate amount of
time indicated in the table.
• Before you store the machine, charge or discharge the batteries to between 40% and
60% (54.3V and 57.3V).
Note:
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
54.3V
55.4V
57.3V
• After charging the batteries, disconnect the charger plug from power during storage to
minimize the discharging of the batteries.
• The machine and charger will shut off after the batteries are fully charged and does not
turn back on unless the charger cord is disconnected and reconnected.
