IX. BATTERIES & CHARGING 

 

CHARGING YOUR SCOOTER 

To charge your scooter, position the front of the unit next to a standard electrical 
outlet. Be certain the freewheel levers are engaged, and the power is turned off. Plug 
the charger into the scooter, and then into the electrical outlet. When the batteries 
are fully charged remove the charger from the scooter. 

SUGGESTION – The lights on your charger indicate different charge 
statuses. The light indicators can be found on the charger itself, or the 
manual provided with the charger. In most cases your charger will show a 
red or orange light when charging, and a green light when fully charged.  

BATTERY BREAK-IN 

To ensure maximum use from your new batteries fully charge the scooter prior to 
initial use for 8 to 12 hours. Operate your scooter until the battery gauge shows half 
capacity, and then give your scooter another full charge for 8 to 12 hours.  

BATTERY MAINTENANCE & CHARGING HABITS 

To ensure maximum life from your batteries, and continued use of your scooter please 
follow these charging guidelines based on your usage: 

SUGGESTION – If you use your scooter on a daily basis, charge the 
batteries as soon as you are finished with the day’s activities, and leave it 
on the charge until you are ready to use the following day. 

SUGGESTION – If you use your scooter infrequently, charge the batteries 
once a week for 10 to 14 hours.
