How can I get maximum range or distance per charge?
Rarely do you have an ideal driving situation such as smooth, flat, hard terrain with no hills or curves. More often you are
presented with hills, pavement cracks, uneven and loosely packed surfaces and curves. All of these factors affect the
distance or running time per battery charge. The following are a few suggestions for obtaining the maximum range per
charge:
! Always charge the batteries fully prior to your trip.
! Plan your trip in advance to avoid inclines if possible.
! Limit the baggage weight to essential items.
! Maintain 2.4 bar (35 psi) in pneumatic drive wheels.
What type of battery should I use?
We recommend deep-cycle batteries that are sealed and maintenance free. Both AGM and Gel-Cell are deep-cycle
batteries and are similar in performance.
WARNING! Corrosive chemicals contained in batteries. Use only AGM or Gel-Cell batteries to
reduce the risk of leakage or explosive conditions.
Why do my new batteries seem weak?
Deep-cycle batteries employ a different chemical technology than those used in car batteries, nickel-cadmium (nicads), or
in other common battery types. Deep-cycle batteries are specifically designed to provide power, drain down their charge
and then accept a relatively quick recharge. Deep-cycle batteries should be charged as often as possible. They do not have
a "memory" like nickel-cadmium batteries.
We work closely with our battery manufacturer to provide a battery that best suits your power chair's specific demands.
Fresh batteries arrive regularly and are promptly shipped with a full charge. During shipping, the batteries encounter
temperature extremes that may influence their initial performance. Heat robs the charge from the battery, and cold slows
the power available and extends the time needed to recharge the battery (just as with a car battery).
It might take a few days for the temperature of the battery to stabilize and adjust to its new ambient temperature. More
importantly, it takes a few "charging cycles" (a partial drain, then a full recharge) to establish the critical chemical balance
that is essential to the battery's peak performance and long life. It is well worth it for you to take the time to break in the
batteries properly.
How can I ensure maximum battery life?
A fully charged deep-cycle battery provides reliable performance and extended battery life. Keep your power chair's
batteries fully charged whenever possible. Batteries that are regularly and deeply discharged, infrequently charged or
stored without a full charge may be permanently damaged, causing unreliable power chair operation and limited battery life.
How should I store my power chair and batteries?
If you do not use your power chair regularly, we recommend maintaining battery vitality by charging the batteries at least
once a week.
If you do not plan on using your power chair for an extended period, fully charge the batteries prior to storage. Disconnect
the battery harnesses and store your power chair in a warm, dry environment. Avoid temperature extremes such as freezing
conditions and excessively hot conditions, and never attempt to charge a frozen battery. A cold or frozen battery should be
warmed for several days prior to recharging.
