BATTERY CHARGING GUIDELINES
1.
Do not disconnect the charger cord if charging is not complete. The
battery life will be seriously shortened or decayed if the battery is
repeatedly used without being fully charged. Ensure you always charge
the battery fully every time.
2.
Always charge the batteries until the charger LED light turns green. This
means that bulk charging is complete. Never stop charging before the
LED turns green.
3.
Ideally, leave the charger switched on for at least two hours after the LED
has turned green. During this time this charger will trickle charge the
battery to optimise its performance.
4.
If you do not use your powerchair for a long time, still charge the batteries
at least once a week to keep the batteries in a usable condition.
5.
The ambient temperature will affect charging time. Charging time will be
longer in the winter.
6.
After charging, do not leave the charger plugged in to the powerchair, as
this will cause a power drain on the powerchair and temporarily reduce its
range.
7.
The batteries carry a one year manufacturer’s warranty. This warranty
only covers issues relating to manufacturing faults, and not faults relating
to failure to recharge the batteries as instructed above.
8.
Charge in a well ventilated space where it is not directly exposed to
sunlight. Do not charge in surroundings where it is humid or damp. Do
not cover whilst charging.
9.
Do not charge in temperatures less than -10°C or higher than +50°C as the
charger may not work well and the batteries or powerchair may become
damaged.
10.
When a battery is new off-the-shelf it is approximately two-thirds of its
optimum capabilities. During the first 3 – 6 months of use the batteries
will improve to a peak point at which they will remain for 50% - 60% of
their expected lifespan (if maintained and charged correctly, as described
in this manual). At this point the batteries will begin to deteriorate until
they will require replacing. It is for this reason that the batteries must be
correctly charged at all times else the peak point reached may not be the
batteries’ optimum capacity and their lifespan may be reduced.
