18 Charging the maintenance free batteries
The amount of charge in your maintenance free batteries is depending on a
number of factors, including the way you use your wheelchair, the temperature
of the maintenance free batteries, their age and the type of maintenance free
batteries used. These factors will affect the distance you can travel in your
wheelchair. All wheelchair maintenance free batteries will gradually lose their
capacity when they get older.
The most important factor that is reducing the life span of your batteries is the
amount of charge you take from the batteries before you recharge them. The
maintenance free battery life is also reduced by the number of times you
charge and discharge the batteries. Normally the amount of cycles is between
300 and 700 times. To make your maintenance free batteries last longer, do
not allow them to become completely discharged.
Always recharge your maintenance free batteries promptly after they are
discharged. If your battery gauge reading seems to fall more quickly than
usual, your batteries may be worn out. If your wheelchair shows these
indications, please contact your local authorized supplier to have the
maintenance free batteries checked.
18.1 Battery level
The power level of the batteries is displayed on the LCD screen of the joystick
module.
If the maintenance free batteries are fully charged, all ten LED's on the top bar
light up. The more energy is used the more LED extinguish, starting on the
right side.
If only the red LED are still on, it indicates that recharging of the maintenance
free batteries is required.
