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, pavement cracks, uneven and loosely packed surfaces, curves, and wind. All of these factors will affect
the distance or running time per battery charge. Below are a few suggestions for obtaining the maximum range per charge:
n Always charge the batteries fully prior to your trip.
n Plan your trip in advance to avoid inclines if possible.
n Limit baggage weight to essential items.
n Try to maintain an even speed and avoid stop-and-go driving.
What type of batteries should I use?
We recommend deep-cycle batteries that are sealed and maintenance free. Both sealed lead-acid (SLA) and gel cell are deep-
cycle batteries that are similar in performance.
Use these specifications to reorder deep-cycle batteries:
Why do my new batteries seem weak?
Deep-cycle batteries employ a much different chemical technology than that 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. Lead-acid 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 encounter
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 stabilise 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.
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 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.
