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 wind, hills, or curves. More often
you are presented with hills, sidewalk cracks, uneven and loosely packed surfaces, curves, and wind. 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 fully charge the batteries prior to your trip.
! Maintain 35 psi (2.4 bar) in pneumatic drive wheels.
! Plan your trip in advance to avoid inclines if possible.
! Limit baggage weight to essential items.
! Try to maintain an even speed and avoid stop-and-go driving.
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 that are similar in performance.
WARNING! Corrosive chemicals are 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 much different chemical technology than that used in car batteries, nickel-cadmium batter-
ies (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. AGM and Gel-Cell 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 at Pride and are promptly shipped with a full charge. During shipping, the batteries encoun-
ter temperature extremes that may influence 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 to take the time to break in
your battery properly.
NOTE: The useful life of a battery is quite often a reflection of the care it receives.
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.
