24 BOSS 4.5, RF, P3 & P4 OWNERS MANUAL
1. The battery gage on the joystick console 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. Charg-
ing will bring deep cycle discharge condition batteries up to full charge. You will not see maximum battery
life if the batteries are routinely run to the
deep cycle discharge condition.
2. It is best to charge the batteries before they reach the deep cycle discharge condition. Short
charge intervals to keep a battery “topped off” are better than long intervals for bringing a battery up from
deep cycle.
3. Keep the batteries away from heat. Areas with excessive sunshine or excessive heat will cause
a faster loss of charge in the batteries. 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 maximize 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. The PaceSaver charger can be left con-
nected indefi nitely without damaging the batteries.
5. Loose connections can keep the batteries from delivering full 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.
6. Batteries should never be subjected to freezing temperatures. Discharged batteries can be quickly
ruined in freezing conditions.
WARNING:
Do not use a non-sealed liquid lead acid battery. Spillage of battery acid will cause severe
burns and will corrode metal components of the power wheelchair.
Charging Notes:
Regular use of your chair will require regular charging. It is a common misconception that batteries need
to be run into deep discharge before recharging. This is not true and can lead to damage of the batteries if
they are regularly discharged deeply before recharge. Likewise, if batteries are stored or used for a long
period of time without recharge, this may result in permanent damage to the batteries resulting in unreli-
able operation and shortened battery life. Maximum driving range of your wheelchair can be obtained if
the batteries are fully charged prior to a lengthy trip. Because the charger is a fully automatic charger, it
can be "on charge" for an indefi nite period of time without harm to the batteries.
Some chargers have a small cooling fan located inside the charger which is thermostatically controlled and
may come on as internal temperatures rise. This fan may operate at regular intervals. Do not rely on it’s
operation as an indication of charger output. Battery chargers are designed to operate at a high temperature.
