n Infrequent Use
If you use your power chair infrequently (once a week or less), you should charge it at least once per week for
12 to 14 hours.
NOTE: Keep the batteries fully charged and avoid deeply discharging the batteries. Do not charge the
batteries for more than 24 hours.
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, footpath 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:
n Always charge the batteries fully prior to your trip.
n Maintain 2.4 bar (35 psi) in pneumatic drive tyres.
n Plan your trip in advance to avoid inclines if possible.
n Limit the baggage weight to essential items.
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 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 the specific demands of your
power chair. 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 stabilise 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.
