Useful Battery Information
1. The battery indicator in the control panel takes into account time as well as battery
voltage to provide a more accurate estimate of battery capacity while you are driving. The
display simulates a bar graph where all LED's lit represent a full state of charge and a single
red LED represents the lowest state of charge. If, while you are driving, the indicator falls
into the red area, charge the batteries as soon as possible. Charging will bring deep cycle
condition batteries up to full charge. You will not see maximum battery life if the batteries
are routinely run to the
deep cycle condition.
2. It is best to charge the batteries before they reach the deep cycle condition. Short
charge intervals to keep a battery “topped off” are better than long intervals for bringing a
battery up from deep cycle. The charger can be left on overnight or for several days at a time,
but once the batteries are fully charged, it is best to unplug the charger.
3. Keep the batteries away from heat. Areas with excessive sunshine or excessive
heat will cause a faster loss of charge in the batteries. Charging the batteries longer than
necessary will also introduce heat into them. Heat will cause the batteries to lose their charge
and also shorten their life.
4 Storage of batteries is very important to their life span. The very best way to maxi-
mize battery life is to store them in a fully charged condition in a cool place. Then, periodically
charge EVERY ONE TO TWO MONTHS to keep the batteries in this fully charged
condition. Batteries should never be subjected to freezing temperatures. Undercharged
batteries can be quickly ruined in freezing conditions.
5. Loose connections can keep the batteries from delivering their power. Visually check
the battery wire connections in the battery box periodically for looseness. Always connect
the red wire to the positive (+) battery terminal. Connect the black wire to the negative (-)
battery terminal.
WARNING:
Do not use a non sealed liquid lead acid deep cycle battery. Spillage of
battery acid will cause severe burns, and will corrode metal components of the power wheel-
chair.
