VIPER STRETCHER BATTERY (E)
The integrated 37 V battery is a rechargeable battery with capacity
of 5000 mAh and a battery management system (BMS) to extend
its life.
When secured in the VIPER Loading System with a powered
integrated charging system, the stretcher hydraulic system is
disabled, ensuring it cannot be moved up or down when loaded.
Battery Features:
●
Press any height control button to display the approximate
battery charge (1 to 5 bars)
(D) Charging indicator lights (5): When the control height
●
button is pressed, the number of lights illuminated indicates
approximate battery charge. Lights flash green when the
battery is charging in the vehicle on the loading system or
when charging with the supplied external mains battery
charger when outside the vehicle.
(E) Temperature icon: A blue flashing symbol indicates a
●
low battery temperature. A red flashing symbol indicates a
high temperature of one of the electronic components. If the
problem persists, inspect the stretcher.
Sleep Mode: After a period of inactivity, the stretcher will
●
enter Sleep Mode to conserve battery power. Press any height-
control button on the transporter to wake the transporter
from Sleep Mode.
Charging: The integrated charging system (ICS) uses power
●
from the ambulance electrical system to automatically
charge the battery while the stretcher is secured in a VIPER
Loading System. Alternatively, it is possible to charge the
stretcher outside of the vehicle using the supplied external
mains charger which connects to the connector under the
backrest (Figure 4). The recommended ambient temperature
for charging the battery is 0°C - 25°C. Charge the battery in a
stable temperature environment.
Balancing: During balancing the voltages on the individual
●
cells of the battery are equalized. This process starts when
the battery has been fully charged and may take several tens
of minutes. Battery Balancing is indicated by flashing all five
indicator lights.
Fully charge the battery immediately upon receipt of the
stretcher and before using the stretcher. Shipping regulations
require the battery to be shipped with a maximum 30%
charge. Failure to charge the battery in a timely manner can
damage the battery.
To charge a battery inside an vehicle, use a VIPER Loading
System with integrated charging system.
Charge Ferno batteries only with a compatible Ferno charger.
A fully charged new battery allows approximately 50 lifts
cycles with a load of 100 kg. This value is indicative only.
As the battery ages and the number of charge cycles increases,
the number of lifts per fully charged battery decreases. This is
a natural process.

NOTICE
VIPER
Improper charging can cause injury and damage. Charge
the battery only with an approved adapter and Ferno
charger or integrated charging system (ICS).
Modifying the battery can cause injury and damage. Use
the battery only as designed by Ferno.
Use only the original charging adapter. Using a non-
original adapter may cause damage to the product.
Do not connect the charging adapter when the stretcher
is in use or with patient on it. There is a risk of injury to the
operator and patient.
When connected to an external AC voltage network, the
stretcher meets the requirements of protection class I.
To avoid the risk of electric shock, the stretcher must be
connected to a power network with protective earthing.
When the battery capacity drops below 20%, start
charging as soon as possible. There is a risk of the
electronic system shutting down when battery charge
drops below 20%
Fully charge and balance the battery at least once every
2-4 weeks, depending on how often you use the stretcher.
There is a risk of battery failure if this is not followed.
Improper maintenance can cause injury and damage.
Maintain the stretcher and battery only as described in
this manual.
