PROPER BATTERIES TO USE DO NOT USE THIS TYPE OF BATTERY Fig. 7-4 Fig. 7-5 7.2.7 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, tire pressure, weight of the driver, way of driving and utilisation of lighting, if equipped. 60101877-B Controls System • Try to charge the batteries always before you reach the red LED range. The last 3 LED (one red and two orange) mean you have a remaining capacity of about 15%. • Driving with flashing red LED's means an extreme stress for the battery and should be avoided under normal circumstances. • When only one red LED is flashing, the Battery Safe feature is enabled. From this time, speed and acceleration is reduced drastically. It will allow you to move the mobility device slowly out of a dangerous situation before the electronic finally cuts off. This is deep discharging and should be avoided. • Be aware that for temperatures below 68 °F (20 °C), the nominal battery capacity starts to decline. For example, at 14 °F (-10 °C) the capacity is reduced to about 50% of the nominal battery capacity. • To avoid damaging the batteries, never allow them to be fully discharged. Do not drive on heavily discharged batteries if it is not absolutely necessary, as this will strain the batteries unduly and shorten their life expectancy. • The earlier you recharge the batteries, the longer they live. 47
