10. Battery Charging
The battery charger supplied is special to your Mystere and so it may not be suitable for any other powered
mobility product. Only use the charger supplied with your Mystere as other makes of chargers may permanently
damage your batteries and would void the warranty.
The charger is a switchable type to match both 110v and 220/240v power supplies. It should be set at 220/240v
(as supplied). It also has an ON/OFF switch at the rear. Make sure this is ON (110v applies USA only).
To charge your batteries follow these simple steps.
1. Switch OFF your Mystere and remove the key.
2. Plug the charger lead into the socket located at the rear of the handlebar console (Fig 5.1).
3. Push the plug from the charger into a suitable wall outlet and switch on.
4. You will see 2 lights on the front of the charger.
The red light will be indicating mains on and the other one will be amber indicating that the batteries are
charging. When the amber light changes to green, the batteries are fully charged.
5. When the batteries reach their charged state, the charger will automatically stop charging. The lights
will, however, still be on but the batteries cannot overcharge.
6. 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.
7. 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.
8. 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.
9. For the best results your batteries really need to 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.
You will find that the distance that your Mystere 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.
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 Mystere with charger switch 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 Mystere 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. This is particularity important to sealed batteries such as the
type in your Mystere.
If your Mystere is to be stored away for some time, make sure the batteries are fully charged before storing.
Fully charge the batteries before re-using it.
Every six months, check the connections on the batteries, making sure they are tight and clean.
Batteries carry a limited warranty from the original manufacturer, which is subject to a stringent
wear and tear clause. Any battery faults due to a defect by the original manufacturer will normally
become obvious within the first two months. Any gradual deterioration in performance after this
period is normally associated with fair wear and tear; misuse or accidental damage is not covered by
the manufacturer’s warranty.
