WARNING! Corrosive chemicals contained in batteries. Use only Lithium-Ion batteries to
reduce the risk of leakage or explosive conditions.
Why does my new battery seem weak?
Like nickel-cadmium batteries, Lithium-
Ion batteries have a “memory” effect. Lithium-Ion batteries are
specifically designed to provide power, drain down their charge, and then accept a relatively quick
recharge. If the batteries are continually recharged after only being partially discharged, they lose their
ability to hold a full charge.
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 FeatherChair and are promptly shipped with a full
charge. During shipping, the battery encounters 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 will take a few “charging cycles” (a full 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 battery will provide reliable performance and extended battery life. Keep your power
chair’s battery fully charged whenever possible. Batteries that are infrequently charged, repeatedly
charged after only a partial discharge, 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 reflection of the care it receives.
How should I store my power chair and its battery?
If you do not use your power chair regularly, we recommend maintaining battery vitality by charging
the battery at least once per week.
If you do not plan on using your power chair for an extended period, fully charge the battery prior to
storage. Flip the battery switch to the off or “0” position, disconnect the battery, and store the power
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.
What about public transportation?
The FeatherChair-supplied Lithium-Ion batteries are designed for application in power chairs and other
mobility vehicles. Transport of the item on commercial aircraft is subject to federal regulations and
airline policy. We suggest you contact the carrier’s ticket counter in advance to determine that carrier’s
specific requirements, and to ensure your power chair and its Lithium-Ion battery are permitted.
What about shipping?
If you wish to use a freight company to ship your power chair to your final destination, repack your
power chair in the original shipping container if possible and ship the battery in a separate box.
