VI. BATTERIES AND CHARGING
How can I get maximum range or distance per charge?
Rarely do you have an ideal driving situation such as smooth, at, 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 will aect the distance or running time per battery charge. Below 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 baggage weight to essential items.
Try to maintain an even speed and avoid stop-and-go driving.
We recommend charging your batteries for at least 48 continuous hours once per month to improve battery
performance and battery life.
What type of batteries 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 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 dierent chemical technology than that used in car batteries, nickel-cadmium
(nicads), or in other common battery types. Deep-cycle batteries are specically 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 specic demands.
Fresh batteries arrive regularly at Pride and are promptly shipped with a full charge. During shipping, the batteries
encounter temperature extremes that may inuence 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 will take 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 will be well worth it
to take the time to break in your battery properly.
How can I ensure maximum battery life?
A fully charged deep-cycle battery will provide 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.
NOTE: The useful life of a battery is quite often a reection of the care it receives.
How should I store my power chair and its batteries?
If you do not use your power chair regularly, we recommend maintaining battery vitality by charging the batteries
at least once per week.
