The chair won’t go above the speed allowed when the seat is raised beyond a certain point right now. I think it is probably due to a bad switch, but I’m not sure where to start first. I liked the chair and want to get it going again so I can put some of the wider/softer tires on it.

From looking at the Sonnenschein website it looks like they are one of the 512xx... models. To make sure I don’t order the wrong batteries, can anyone tell me for sure which model? The chair is a front wheel drive model about five to ten years old.

I’m searching for a variable voltage charger now with somewhere around ten volts to charge an MK or Sonnenschein battery.
