6. BATTERY CHARGING AND CARE
6.1 BATTERIES
Always fully recharge the batteries after use. Never drain the batteries down until they are totally flat. For
ease of maintenance and reliability, all the Mambo powerchairs use off-board chargers.
To recharge the powerchair, follow the procedure below step by step:
1. Switch off the powerchair.
2. Connect the charger’s power cord onto the power outlet.
3. Locate the 3-pin charging socket at the end of the controller. Then connect the charger’s round plug to
the charging socket.
4. Turn on the switch on the charger. The charger should have an orange LED illuminated when charging
which will turn green when the bulk of the charging is complete.
5. To ensure optimum performance a 12 hour charge is recommended.
 Suggestion
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. Therefore be sure to
charge the battery fully every time.
2. Always complete the charging until the charge LED light turns green. NEVER stop charging before it
is complete.
3. When fully charged, the battery charger will still trickle charge the battery to ensure optimum range.
4. If you do not use your powerchair for a long time, it should be charged at least every week to keep the
battery in a fully usable condition.
5. Charging time will be affected by the ambient temperature. Charging time will be longer in the winter.
6. After charging, do not leave the charger socket plugged in to the powerchair, as this will cause a power
drain on the powerchair and temporarily reduce it's range.
7. The batteries carry a twelve-month 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.
Attention: Please follow the rules below to avoid accidents while charging.
1. Please use Mercury 24V chargers only, and recharge the battery to its full capacity every time. You may
damage the battery and powerchair if you use a charger which is not to the correct specification.
2. Never disassemble or modify the charger.
3. Please charge in a well-ventilated space where it is not directly exposed to the sunlight. Do not charge
in surroundings where it is humid or under rainfall and morning dews.
4. Do not cover with a waterproof cloth or other objects while charging.
5. Do not charge in temperatures less than -10°C or higher than +50°C as the charger may not work well
and the batteries may become damaged.
