We bought these for our H4n recorder which we used to record sound from the stage. We had 4 hours on the batteries and thought it might be worth a try. Can't beat the title and Heavy Duty? Well when we saw after the first show that the recorder was broken we thought it was a recorder or we didn't have fresh batteries (we use new ones for every show). So the next performance, we checked it after the first act, about an hour and a half later, and it was over. So maybe it's the batteries. We borrowed some Ray-o-vac batteries from the sound engineer and put them in for the second act. At the end of the show (another hour and a half) the recorder was still working and the batteries had 3 out of 4 divisions left. I came home and looked at the specs of these batteries but found nothing. I then noticed on the Panasonic site that it says "Heavy Duty" but then it says it's for "Low Power Devices". Nowhere in the Revain list is this; only they are heavy duty. So I have 40 batteries that I cannot return. Instead, I'm looking for Ray-O-Vac.
