5.2 Main battery
Note:
The battery and charger instructions from Milwaukee
supersede those in this manual. For additional information, see
the manuals provided with these components.
The term “main battery” is used in this manual to describe the
Milwaukee
®
28-Volt DC, lithium-ion battery (Figure 9). The
control panel also uses batteries. See
Control-Panel Batteries,
page 37.
The main battery powers the belts. It is sealed for resistance
to precipitation, dirt, body fluids, cleaning solutions, etc. Use
only the Ferno-approved battery and battery charger. A battery
is provided with purchase of a chair or PowerTraxx retrofit kit.
For additional batteries or chargers, see
Accessories,

●
Lithium-ion batteries have no “battery memory.” You do
not need to fully discharge the battery before recharging it.
●
A typical fully-charged battery provides power to move
an average patient (250 pounds) up more than 200 stairs.
●
Typical charging time is about one hour. Actual charging
time varies based on frequency of recharge, depth of
discharge, and battery age. If a battery becomes deeply
discharged, extend the charging time.
●
Patient weight, extreme temperatures, and the combination
of using the chair to go up and/or down stairs affect the
amount of use available from each battery charge.
●
The manufacturer’s recommended operating temper-
ature
for the battery itself
is 14°F to 120°F (-10°C to
49°C). The battery may be used in temperatures outside
this range. Battery capacity can be affected if the battery
is stored for long periods below 0°F (-17°C) or over
150°F (66°C).
●
Recycle batteries at the end of their service life. Do not
dispose of batteries with municipal waste. See
Recycling
Notice,
page 4.
●
Do not open the battery. There are no serviceable parts
inside the battery.

Press the two red release buttons (Figure 9) to disconnect
the battery from the chair or battery charger.
●
To check the charge of the main battery, press the test button
on the battery. See
Battery-Charge Indicator,
page 15.
●
Store the battery ONLY in a cool, dry place. DO NOT
store where temperatures may exceed 120°F (50°C).
●
If two batteries are available, keep the spare battery
charged and ready for use.
