POWERCHAIR/SCOOTER CHARGING TIPS*
1) Fully recharge any new battery prior to its initial use. This brings the battery
up to about 90% of its peak performance level.
2) Give the batteries another full charge of 8 to 14 hours after using the first
day. The batteries should now perform at over 90% of their potential.
3) After four or five charging cycles, the batteries top off at 100% charge and
last for an extended period.
Batteries and Charging- Frequently asked Questions
How can I get maximum range or distance per charge?
Rarely do you have an ideal driving situation such as a 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 30-35 psi 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.

Why do my new batteries seem weak?
Deep-cycle batteries employ a much different chemical technology than
that used in car batteries. 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.
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.
REMEMBER: 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 batteries fully charged whenever
possible. Batteries that are infrequently charged or stored without a full
charge may be permanently damaged, causing unreliable operation and
limited battery life.
How should I store my power chair and batteries?
If you do not use your chair regularly, we recommend maintaining
battery vitality by charging the batteries at least once a week.
If you do not plan on using your chair for an extended period, fully
charge the batteries prior to storage. Disconnect the battery harnesses
and store the chair in a warm, dry environment. Avoid temperature
extremes, such as freezing 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.
