Need a replacement battery and charger for my Electric Bike/Scooter?

I bought it over 7 years ago, the business is no longer there.  The scooter is a no-name.  
1. It no longer will charge and I need to replace the battery.
2. The lights no longer go on high beam.

Where do I start?

I do not live near a large city - this would have to be DIY.

Got a picture of the battery ?

That isn't the battery in the picture with the Letter/Number combination?
Can't tell from the context. There's no voltage rating I can see, or Ah figures.

Like Steve said please show the battery at the feet.
This scooter could really go 40 km/h or 22mph ?
How far before pedaling when it was new ?
