Jah -- I didn't monitor sonic performance during the batt test, so I don't know if the V3 exhibited any degradation. Just didn't think of it at the time - I figured the Grace folks wouldn't place the cut-off voltage so low that it would degrade performance, but...something to keep in mind if/when I run another test.
Daryan -- You got 7 hours out of what capacity SLA...7AH? 10AH?
