Storage And Maintenance; Instructions On Using The Batteries - Invacare FDX User Manual

11.2.2 Storage and Maintenance

Follow the instructions listed below to ensure safe use and longevity of the batteries:
• 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.

11.2.3 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, tyre pressure, weight of the driver, way of
driving and utilisation of lighting.
• Try to charge the batteries always before you reach the red LED range.
