Well, the Floureon brand rechargeables seem to be of decent quality: plenty of capacity, however they DO cause the restart issue, possibly because the male terminals are on the small side: allowing for a bit of movement which in turn disrupts the supply of power.
however, I tried Miguel's field fix with the bracken and it worked
I will also try a strip of tape around them to prevent the restart issue.
How has everyone elses SDC's been performing this summer? vacuuming up the shiny stuff one hopes!
