Battery Charging; A Guide To Safe And Lasting Batteries - TGA MAXIMO Operating Instructions And Owner's Handbook

10. BATTERY CHARGING

The battery charger supplied is special to your Maximo and so it may not be suitable for any other powered
mobility product. Only use the charger supplied with your Maximo as other makes of chargers may permanently
damage your batteries and would void the warranty.
To charge your batteries follow these simple steps.
1. Switch OFF your Maximo and remove the key.
2. Plug the charger lead into the socket located on the battery case.
3. Push the plug from the charger into a suitable wall outlet and switch on.
4. A red light on the charger will come on advising power is on.
5. An orange light will come on indicating it is charging.
6. After a further period of time a green light will show advising the batteries are fully charged.
7. At this time the charger can be disconnected and the Maximo is ready for use. NB At the point the green light
comes on the charger will automatically stop charging although the light will still be on. The batteries cannot
overcharge.
8. Although to get out of trouble the batteries can be put on charge for a short period of time, it is always best to
go through a complete charge cycle each time. Excessive short period charging will be detrimental to battery life.
9. 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.
10. Depending on the depth of the discharge, the minimum time taken to recharge serviceable batteries fully will
vary up to 12 hours. Please note that this time may increase as batteries get older. During periods without use
(perhaps during the winter) it is wise to charge the batteries every 4 to 6 weeks.
11. For the best results your batteries must be cycled for their first 10-15 charges. This means run them down as
much as you safely can in use and then give them a full charge. They will not work at their best until this process
has been carried out. It can also prolong battery life.
You will find that the distance that your Maximo can travel will gradually increase over the first few weeks of use
as the batteries reach their optimum efficiency after approximately 12 cycles of discharge and recharge. NB When
the charger is plugged into Maximo an automatic inhibit device will shut down the scooter stopping anything being
used whilst plugged into the charger.
From time to time the type of charger may change so please read instructions on charger.
Care! Warning
All TGA lithium battery packs contain a temperature sensor. When this sensor records a temperature of 10°C, the
internal circuit board will stop the battery charger from working in order to protect the battery cells. Once the
battery pack reaches a temperature of approximately 20°C it will then allow the charger to start working again.
This is only relevant if the pack drops below 10°C, so long as the battery pack is stored and remains above 10°C
then the charger should work as normal, standard room temperature is sufficient
Care! Warning
* 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.
* Do not dismantle the charger. This will void the warranty.
* Do not leave charger plugged into your Maximo with charger switched off as this may discharge your batteries.
* For a complete charge – Do not switch off, unplug or interrupt the recharge cycle until the charging cycle has
completed.

11. A GUIDE TO SAFE AND LASTING BATTERIES

* For longest life, your batteries should be recharged after reasonable use.
* If your Maximo is not used for a period of time, a refreshing charge should be given every 4-6 weeks. Never
leave your batteries in a discharged condition.
