6.0 BATTERY AND CHARGER
6.5 Low battery levels (Fi 6.3)
WARNING
ALWAYS be aware of the battery life. Check it frequently. It is best to carry a
spare battery when taking prolonged rides. Battery level (D) is shown on the
controller display. When battery level reaches the last battery indicator light
(one light remaining), change to a replacement battery.
1.
First get the wheelchair to a safe place. Turn the power button off and
switch to the replacement battery. If no replacement battery is available,
leave the power button turned off while driving.
2.
The battery should only be changed by someone trained in proper battery
installation.
6.6 Battery safety
WARNING
The battery on the device is not very large but stores a large amount of charge.
Improper use can cause damage or in certain circumstances lead to burns or fi re.
1.
Only use the battery for the intended purpose of power assist for a
wheelchair.
2.
Keep the battery out of reach of children and anyone who is not familiar
with it.
3.
When transporting the wheelchair, remove the battery from the device.
4.
When the battery is not in use, store it in the travel bag.
5.
If the battery housing is damaged, a corrosive liquid (KOH) can be emitted.
Avoid any contact with the skin and discontinue use, if any damage to the
device is noticed.
6.
Do not allow battery connection clamps to come into contact with wires or
metal.
7.
Do not expose the battery to impact; do not add parts to or remove parts
from the battery.
8.
Do not expose the battery to heat or place near fi re or water.
9.
Do not use a broken or damaged battery.
10.
Do not disassemble or modify the battery.
11.
Do not charge or store the battery near pets or children.
6.7 Lithium Ion battery
WARNING
Temperature
a.
While travelling, if the internal temperature of the lithium ion
battery becomes too high or too low, the battery will not provide
power to the unit. The power assist function will not operate.
b.
If the unit is in the drive position it will not operate. It may be
necessary to manually remove the drive unit from the wheelchair.
c.
When descending down a slope on the wheelchair, the drive motor,
contrary to normal operation, generates electricity and charges the
battery. Charging a lithium Ion battery in this way when its
temperature is below 32°F (0°C) or above 113°F (45°C) will cause its
deterioration. To protect the battery in these conditions, the device
may stop itself.
2.
Charging:
a.
The Lithium Ion battery uses the specialized plug when charging the
battery in the unit.
b.
The battery can be removed to charge.
c.
Do not use a charger other than the one provided with the specifi c
battery.
Failure to heed this warning may result in damage to the battery and/or the
charger unit.
6.8 Checking the battery (Fi 6.4)
The battery capacity and charging progress (E) is shown on the controller. The
total capacity is shown by LED indicator lights. Each light represents about 30% of
the total capacity of the battery.
1.
What each battery level means
There are four LED lights (E) on the battery display. (Fig. 6.4).
2.
Lithium Ion battery life:
a.
When the battery can no longer be charged, the battery indicator lamp
no longer lights.
b.
Recycle battery. Do not dispose of in bodies of water or sewer
systems. Dispose of in accordance with local, state, and federal
regulations.

6.9 Charger safety
The charger for the device is a very sensitive piece of equipment. Improper use
can cause damage or in certain circumstances lead to burns or fi re.
1.
When charging always use the charger supplied.
2.
Always charge on a level surface. After use do not keep it plugged into the
power outlet.
3.
Keep the charging unit out of reach of children and anyone who is not
familiar with it.
4.
Do not use chargers that have a damaged cord, or chargers that have been
dropped.
5.
The charger design is focused on dust-proof and water-proof (IP21). Please
do not use it in direct sunlight or high temperature environment
(32°F to 113°F [0°C to 45°C]).
6.
Do not use batteries not designed for the charger.
