4. Charging the battery
CAUTION
The battery and charger are for the WHILL Model F only. Do not charge the battery by using a
non-designated charger or charge non-designated batteries with the charger provided with the
device.
There is a risk of malfunctions.
Do not use batteries with the cap damaged or cracked.
If you do so, there is a risk of electric shock, short circuit, and fire.
• If the device does not start properly even though the charged battery is inserted to the device and the device is
turned on after five seconds have elapsed, remove the battery, then attach the battery again after 10 seconds.
• The charger is for indoor use only. Do not charge the battery outdoors.
• The device decelerates when the battery temperature drops significantly in low-temperature (0°C or lower)
environments. If this happens, the drive speed on level ground is restricted to 4 km/hour at maximum.
Although the battery temperature is not the same as the air temperature or ambient environment, ensure that
the battery is not left for a long time in 0°C or lower environments before driving.
• The device sometimes comes to a stop if an attempt is made to go up steep inclines when the battery
temperature is low.
• The device decelerates if it is driven on a downhill slope with the battery close to fully charged. The device
decelerates considerably more the lower the battery temperature becomes.
• We recommend charging the battery regularly, each time you finish using it for example, so that the device
has a fully charged battery when it needs to be used. Insufficient battery power can be prevented by using a
fully charged battery the next time the device is boarded. Although the device can be used without the battery
cha
rged fully, in an emergency, the device may get stuck while driving if the battery charge level is low.
• If you have any questions about the battery, please contact your dealer or customer support.
