Commonly Asked Questions and Possible Answers
Why has there been a sudden loss of power?
1. Undercharged batteries. Check the BATTERY indicator. The BATTERY indica-
tor indicates the charge condition of the batteries while you are driving. The indica-
tor will not indicate the “true condition” of their capacity until the wheelchair has been
setting on, in an idle condition, for several minutes. The green area corresponds to a
good charge. The red area corresponds to a low charge, or a deep cycle condition.
It is possible to drive the wheelchair with the batteries in a deep cycle charge condi-
tion, but once they drop below a certain level of power, they will fail and you will be
stranded. If, while you are driving, the indicator falls into the red area, charge the
batteries as soon as possible. Charging will bring deep cycle condition batteries up to
full charge. You will not receive maximum battery life if the batteries are routinely run
to the deep cycle condition.
2. Under-inflated tires. Check for proper inflation (check the specifications for your
particular wheelchair).
3. Excessive weight on the wheelchair. Refer to the specification chart for the maxi-
mum rider weight.
4. There may be other motor or driving mechanism malfunctions. Consult with
your dealer.
Will leaving the batteries for a long time damage them?
Yes. Storage of batteries is very important to their life span. The very best way to
maximize battery life is to store them in a fully charged condition in a cool place. Then
periodically ( every 1-2 months!) charge to keep the batteries in this full charge condition.
Do not store in cold or freezing temperatures. Batteries should never be subjected to
freezing temperatures. Undercharged batteries can be ruined quickly in freezing conditions.
