Battery Characteristics
1.
The travel distance may be shorter than usual, depending on the
terrain, temperature, and the method used to charge the battery.
•
When using the wheelchair in locations where there are frequent
inclines and numerous curbs, the battery consumes more power
than under ordinary travel conditions, resulting in a shorter
travel distance.
•
At low temperatures, battery operation is somewhat weaker, and
the travel distance is shorter.
•
If the battery is repeatedly charged before it has completely run
down, the capacity decreases, and the travel distance is shorter.
(If refresh charging is done properly, this can be avoid)
•
The above problem is particularly likely to occur if the battery is
charged with a high ambient temperature. (The recommended
ambient temperature range is 10 to 30 degrees C.
2.
Even if the battery is correctly used, the performance
deteriorates gradually with the passage of time.
•
The service life of a nickel hydrogen battery varies depending
on the way it is used, but is approximately one year or 300
cycles. (This can also be judged by looking at the capacity
display after the battery has been charged.)
•
As the level of deterioration advances, the capacity display
becomes less stable. We advise consulting the dealership where
the battery was purchased, and replacing it with a new without
waiting until deterioration has proceeded too far.
3.
The capacity diminishes naturally even if the battery is not used
(self discharging).
•
Even if the battery is not used for a long period of time, the
remaining capacity display should be checked periodically, and
the battery recharged at appropriate intervals. If the battery is
being stored for a long period of time and it is not possible to
charge it, the fuse should be removed from the battery, to
suppress self – discharging. (When the fuse is removed, the
capacity display lamp no longer lights correctly, but operation
returns to normal when the battery is charged again.)
