peak electricity rates. The charge time may be as much as ten hours depending on the state of charge in
the battery. This time may increase as the battery gets older. It is not advisable to put batteries on
charge that are already fully charged.
6.
Always disconnect the mains supply before disconnecting the battery. Do not leave the charger connected
to the battery when the mains supply is either switched off or disconnected. This may cause the battery to
discharge.
7.
The battery should not be run completely flat or you may find that you are unable to recharge it. (Contact
your local dealer or TGA.)
8.
If the Powerpack is going to be put away or stored for some time, always ensure the battery is fully
charged before storing. To avoid battery deterioration, the Wheelchair Powerpack should not be left for a
period of two months or more without charging.
9.
Although to get out of trouble the batteries can be put on charge for a short period of time, continual
charging in this manner will shorten battery life and performance will be reduced.
10. For the best results and to prolong battery life try to run the battery down by at least 50% before
recharging and in addition it is always best to go through a complete charge cycle each time.
11. For the best results it is very important that your battery is cycled for the first 10-15 charges. This means
run it down as much as you safely can in use and then give it a full charge. Your battery will not work at
its best until this process has been carried out.
Care! Warning
• Do not allow charger to get wet or use in the rain
• Do not smoke or use a naked flame while your batteries are being charged
• Do not use the charger if it has received a sharp blow, been dropped or otherwise misused in any way. Take it to a
qualified technician for inspection
• Do not dismantle the charger. This will void the warranty.
• For a complete charge – Do not switch off, unplug or interrupt the recharge cycle until the charging cycle has
completed. Make sure that the charger indicator light is green before you unplug your charger.
