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
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:
l
Charge 18 hours prior to initial usage.
l
We recommend charging the batteries daily after 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.
l
When the battery indicator reaches the red LED range,
charge the batteries for at least 16 hours, even if the
display reads that the charge is complete.
l
Try to provide a 24 hour charge once a week to make sure
that both batteries are fully charged.
l
Do not cycle your batteries at a low state of charge without
regularly recharging them fully.
l
Do not charge your batteries under extreme
temperatures. High temperatures above 86 °F (30 °C) are
not recommended for charging as well as low
temperatures below 50 °F (10 °C).
l
Use only charging devices in Class 2. This class of chargers
may be left unattended during charging. All charging
devices which are supplied by Invacare comply with these
requirements.
l
You cannot overcharge the batteries when using the
charger supplied with your mobility device, or a charger
that has been approved by Invacare.
