9.1.1 The main fuse
The entire electric system is protected against overload by two master fuses. The master fuses are
mounted on the positive battery cables.
NOTE
A defective main fuse may be replaced only after checking the entire electric system. An
Invacare® specialised dealer must perform the replacement. You can find information on the
fuse type in chapter "Technical specifications" starting on page 84.
9.2 Batteries
9.2.1 What you need to know about batteries
Power is supplied by two 12 V batteries. The batteries are maintenance-free and only need regular
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 approx. 10 - 20 charging cycles. How fast the batteries
discharge depends on many circumstances, such as ambient temperature, condition of the surface
of the road, tyre pressure, weight of the driver, way of driving and utilisation of lighting.
