 WARNING
Make sure power to the wheelchair is OFF before performing this section.
NEVER allow any of your tools and/or battery cable(s) to contact BOTH battery
terminal(s)/post(s) at the same time. An electrical short may occur and serious
personal injury or damage may occur.
The use of rubber gloves is recommended when working with batteries.
Always use a battery lifting strap when lifting a battery. It is the most convenient
method and assures that the battery acid will not spill. It also helps to prolong the
life of the battery.
Avoid storage or use near external flame or combustible products.
DO NOT tip the batteries. Keep the batteries in an upright position.
Invacare strongly recommends that battery installation and battery replacement
always be done by a qualified technician.
After ANY adjustments, repair or service and BEFORE use, make sure all attaching
hardware is tightened securely - otherwise injury or damage may result.
Battery terminal configuration shown below MUST be used. Batteries that have the
reversed terminal configuration MUST NOT be used - otherwise serious injury or
damage may occur.
 CAUTION
When connecting the battery cables to the battery(ies), the battery cable(s) MUST
be connected to the battery terminal(s)/post(s) as shown in FIGURE 11.3 on page
108 - otherwise damage to the battery may result.
For proper battery connection, batteries MUST use post style terminals with
mounting holes through the terminal.
