[Supras] Anyone have any issues with the Exide Sub

[Jeff Mohler]

Then..why are you dropping voltage at idle?

Thats -not- normal, and its not the battery, it should be able to maintain
steady voltage even at low RPM, even if its not PEAK voltage.

You could load test the battery, see what real reserve it has..but..youve
had multiple cells now..
