Batteries and Battery Chargers 
 

Batteries 

Charge the batteries completely (8-12 hours) prior to first use. 

The ROMA 

Sorrento 

is supplied with closed battery packs which contains two 

34/36Amp, 12 Volt sealed lead acid batteries. The battery packs are situated 
under the front of the seat and can be removed by lifting them away from the 
chassis. 

Low temperatures, rough terrain and the weight of the user can affect battery 
performance. Your battery gauge is a guide only to the level of charge remaining 

in your batteries and will give its best indication while the scooter is moving. 
 

Note: Batteries recommended by ROMA MUST be used if they need to 
be replaced. An authorised ROMA dealer must carry out battery 
replacement. 

 
Battery Charger 

The battery charger is a 5-amp switch type off board. The battery charging ports 

are located on the battery pack* and the left side of the tiller (see images). *This 
special feature allows the batteries to be charged independently of the main 

scooter. 
Before using your scooter for the first time be sure to fully charge the batteries, 
this may take up to 12 hours. 

To charge the batteries connect the 3-pin male charger plug into the charging 
socket on the battery pack or tiller. Plug the 3-pin mains plug into a wall socket 

and switch on. A constant red light will show when the battery charger is 
connected and charging is underway (The green LED will flash if there is a break 
in the connection). The red light indicates that the batteries are receiving charge. 
The  green LED will light when the charging cycle is complete

Always turn off 

mains power to the charger before disconnecting the plug from the battery box. 

To charge off board, the battery packs must be arranged as shown in the 
following image as the contacts must connect to create a circuit. 
 

Caution! Do not charge the batteries for longer than 12 hours. Always 
charge the batteries in a well-ventilated indoor area. You must still 
maintain charging the batteries even if the scooter is not to be used 
for a prolonged period of time (2 to 3 weeks). Failure to do so could 
result in permanent damage and render the batteries unusable. 
Wherever possible do not interrupt the charge cycle until the batteries 
are fully charged. Continual interruption can permanently damage the 
batteries. If the charging lead should get damaged discontinue use 
immediately and seek a replacement from your dealer. ONLY USE THE 
CHARGER SUPPLIED WITH YOUR SCOOTER. Do not leave the charger 
plugged into to the charger port after the charge is complete. 
ALWAYS remove the keys from the scooter when charging. 

 

Disposing and recycling of used batteries 

Batteries must always be recycled correctly. Do not dispose of them with your 

domestic refuge. 

 
For further information regarding your nearest recycling facility please contact 

your local authority.
