Ill vote YES these work fine as well.
The one thing I have noticed, is that they dont always charge back up to the same levels and that they loose about 0.10v per day just sitting around (so dont assume they will be usable in a pinch for time)... they also dont wear down at the same rate from show to show (not sure if that is related to the difference in shows (location, SPL, etc)), but I will still continue to use mine until the recharged voltage is lower than 9 and I am currently seeing 11.15 on average off the charger (with most readings once the batteries have cooled to room temp)
