Invacare® Storm®⁴ Series
•
Always store the batteries fully charged.
•
Do not leave the batteries in a low state of charge for an
extended length of time. Charge a discharged battery as soon
as possible.
•
In case your mobility device is not used for a longer period
of time (that is more than two weeks), the batteries must be
charged at least once a month to maintain a full charge and
always be charged before use.
•
Avoid hot and cold extremes when storing. We recommend to
store batteries at a temperature of 15 °C.
•
Gel and AGM batteries are maintenance-free. Any performance
issues should be handled by a properly trained mobility device
technician.

Instructions on using the batteries
CAUTION!
Risk of damaging the batteries.
–
Avoid ultra-deep discharges and never drain your
batteries completely.
•
Pay attention to the Battery Charge Indicator! Charge the
batteries when the Battery Charge Indicator shows that battery
charge is low.
How fast the batteries discharge depends on many
circumstances, such as ambient temperature, condition of the
surface of the road, tire pressure, weight of the driver, way of
driving and utilisation of lighting, if fitted.
•
Try to charge the batteries always before you reach the red LED
range.
The last 3 LED (two red and one orange) mean a remaining
capacity of about 15 %.
•
Driving with flashing red LED’s means an extreme stress for the
battery and should be avoided under normal circumstances.
•
When only one red LED is flashing, the Battery Safe feature
is enabled. From this time, speed and acceleration is reduced
drastically. It will allow you to move the mobility device slowly
out of a dangerous situation before the electronic finally cuts off.
This is deep discharging and should be avoided.
•
Be aware that for temperatures below 20 °C, the nominal
battery capacity starts to decline. For example, at -10 °C
the capacity is reduced to about 50 % of the nominal battery
capacity.
•
To avoid damaging the batteries, never allow them to be fully
discharged. Do not drive on heavily discharged batteries if it is
not absolutely necessary, as this will strain the batteries unduly
and shorten their life expectancy.
•
The earlier you recharge the batteries, the longer they live.
•
The depth of discharge affects the cycle life. The harder a
battery has to work, the shorter is its life expectancy.
Examples:
– One deep discharge stresses the same as 6 normal cycles
(green /orange display off).
– The battery life is about 300 cycles at 80 % discharge (first 7
LED off), or about 3000 cycles at 10 % discharge (one LED
off).
The number of LED can vary depending on the
remote type.
•
Under normal operation, once a month the battery should be
discharged until all green and orange LED are off. This should be
done within one day. A 16 hour charge afterwards is necessary
as reconditioning.

Transporting batteries
The batteries supplied with your mobility device are not hazardous
goods. This classification is based on the German GGVS Hazardous
Goods Road Transport Ordinances, and the IATA/DGR Hazardous
