Traveling
with a battery in your wheelchair or scooter
Both
automobiles and electric wheelchairs (or scooters) use
batteries, but not all batteries are the same or used
for the same purpose. Automobiles use a battery to start
the engine to get the car underway, while wheelchairs
use a battery as their continuous source of power. For
this reason, traditional car batteries will not work
very long, or at all, in a power wheelchair. Instead,
power wheelchairs and scooters need a "deep-cycle"
battery capable of delivering hours of continuous power.
The
"deep-cycle" cousin of the traditional automobile
lead-acid, "wet-cell" battery can also be
found on a power wheelchair. Wet-cell deep-cycle batteries
on power wheelchairs is not the type of battery we recommend
for any sort of travel. Traditional wet-cell batteries
contain sulfuric acid that can spill from a tilted battery
or leak from a hairline crack in the battery case. Any
acid that escapes from a wet-cell battery will corrode
your wheelchair, your wiring, or maybe some important
part on an aircraft. That is why most air carries refuse
to carry spillable wet-cell batteries when they remain
attached to a wheelchair. Travelers should expect airlines
to remove the wet-cell battery(s) from their wheelchair
and seal them in a chemical-proof, spill-proof container.
At the other end of the flight the wet-cell batteries
and the wheelchair will be delivered separately...most
often left on the jetway for you to reassemble.
For
traveling, we recommend sealed dry-cell or gel-cell
batteries. These batteries also contain lead plates
and sulfuric acid but since they are sealed, their acid
can not escape, cause damage, or crash a plane. If the
case around the battery cracks, the material inside
is dry, or like Jello®, and takes a long time to
leak. Gel and dry cell batteries may be a little more
expensive but, for their ease of traveling on aircraft
and their low potential for leaking acid on your wheelchair
or an important airplane control, they are a worthy
investment.
An
important note: If you are changing battery types from
wet-cell to dry-cell or gel-cell, you must have a battery
charger designed for your new type of battery. Dry-cell
and gel-cell batteries require a special type of charger.
When
traveling on an aircraft, we suggest making it easy
for the airline personnel to disconnect the main power
wire from the battery. Hard to find and hidden connections
invite the airline staff to remove the entire battery
box. This may mean some disassembly of your wheelchair
at the beginning of your journey and could mean that
removed parts might night make it to the destination
with your wheelchair and battery. If the main power
wire connects directly to the side of your battery box
make a small label covered by clear tape reading "Disconnect
Battery Here." If the main connections are hidden,
have a repair shop install new "quick lock /quick
release" connections in a visible location. Mark
each side of the "quick lock /quick release"
connection with a small label reading "Disconnect
Battery Here." Colored electrical tape (available
from most hardware stores) wrapped around the wire near
the "quick lock /quick release" connection
also helps to identify the power disconnect point.
When
it comes to traveling outside of the USA, a little more
rocket science is needed to charge your battery. The
standard US electrical current is 110 volts while European
standard current is 220 volts. The discrepancy in current
means that plugging your 110 volt battery charger into
a 220 volt European powerhouse outlet will overwhelm
your charger with an extra 110 volts, overload your
circuits and destroy your wheelchair. To prevent this
you must use a "step-down converter" that
will step-down, or reduce the 220 volts European current
to 110 volts. HOWEVER...not just any step-down converter
will work. The converter units are designed to handle
different power requirements. Less expensive units can
be used for electric shavers and CD players, heftier
models for hair dryers while beefy commercial models
are for wheelchair batteries. We recommend contacting
the manufacturer of your wheelchair to learn their recommendations
and power requirements. Many manufacturers offer their
own products, or can recommend products from other manufacturers
that will not void the warranty on your wheelchair.
REMEMBER...there are no inexpensive "deals"
when it comes to purchasing a step-down converter for
a power wheelchair. Without a properly rated step-down
converter, your first attempt at charging your battery
in Europe will be your last!
