My wife had the SCS Burst rechargeable for about a year. It worked okay in the beginning but not as well as her initial ketamine treatments but that doctor retired so this was the only route available with the doctors here. After about 10 months, her CRPS leg started going out on her and she noticed the stimulator was not as effective. 12 months in, her battery overheated (much like a cell phone battery) and burned her from the inside. Since then, she has been having worsening bowel issues and cannot pass stool on her own. The battery was removed and replaced the the SCS non-rechargeable but was only turned on for a short time. The battery is a lot bigger and seems to be making the bowel issues even worse than before. We found a different doctor who will go back to the ketamine treatments that had originally worked for her. She will be having the current battery taken out.
