Invacare® AVIVA® Storm RX
The battery isolation switch A is located on the right
front side of the battery box.
The battery isolation switch is an additional safety
feature of the controls protection system. When the
system is overloaded, the battery isolation switch
switches off automatically. In a hazardous situation or
when the mobility device starts to behave erratically,
the battery isolation switch can be used to isolate the
battery source quickly.
Also, it can be used to switch off the power supply of
your mobility device manually, when the mobility
device is transported without surveillance, for example
while traveling in a plane. Refer to2.5 Travel
Information, page 8.
Use the battery isolation switch A to disconnect
the power.
Disconnect (O) — Push the switch towards the
l
FRONT of the wheelchair. The power will turn off.
Connect (I) — Push the switch towards the BACK of
l
the wheelchair. The power will turn on.
7.4 Batteries
Power is supplied by two 12 V batteries. The batteries
are maintenance-free and only need regular charging.
In the following, you find information on how to
charge, handle, transport, store, maintain, and
use batteries.
7.4.1 General Information on Charging
31
New batteries should always be fully charged once
before their first use. New batteries will be at their full
capacity after having run through approximately 10 -
20 charging cycles (break-in period). This break-in
period is necessary to fully activate the battery for
maximum performance and longevity. Thus, range and
running time of your mobility device could initially
increase with use.
Gel/AGM lead acid batteries do not have a memory
effect like NiCd batteries.
7.4.2 General Instructions on Charging
Follow the instructions listed below to ensure safe use
and longevity of the batteries:
Charge 18 hours prior to initial usage.
l
We recommend charging the batteries daily after
l
every discharge even after partly discharge, as
well as overnight. Depending on the level of
discharge, it can take up to 12 hours until the
batteries are fully charged again.
When the battery indicator reaches the red
l
LED range, charge the batteries for at least
16 hours, even if the display reads that the
charge is complete.
Try to provide a 24 hour charge once a week to
l
make sure that both batteries are fully charged.
Do not cycle your batteries at a low state of charge
l
without regularly recharging them fully.
Do not charge your batteries under extreme
l
temperatures. High temperatures above 86 °F (30
°C) are not recommended for charging as well as
low temperatures below 50 °F (10 °C).
Use only charging devices in Class 2. This class of
l
chargers may be left unattended during charging.
All charging devices which are supplied by Invacare
comply with these requirements.
You cannot overcharge the batteries when using
l
the charger supplied with your mobility device, or
a charger that has been approved by Invacare.
Protect your charger from sources of heat such as
l
heaters and direct sunlight. If the battery charger
overheats, charging current will be reduced and
the charging process delayed.
7.4.3 How to Charge the Batteries
Refer to the user manuals for your remote and battery
charger for the position of the charging socket and
further information about charging the batteries.
