How long do the batteries on this device last?

I bought this a several months ago and they are still going strong! Not sure for the longer haul because I have not had the product long enough to have them wear out yet. Hope that helps.

I've used mine everyday for 9 months and they are still working... So a long time!

Not sure still using the original . It's been a few months I believe. I continue to turn it on and off when in use and not. I also bought a whole sleeve of batteries as well so I didn't have to find them but so far so good still working great

It lasts quite a while. I don't use mine much but I have only put one set of batteries in.

I have had it for a few months. Use it a few hours a week. Haven't had to replace the batteries yet.

The device takes a standard 9 volt battery. I have no idea how long the battery will last. Mine is still going strong. My in laws have a couple of unruly Dogs that jump all over the furniture and me. I quietly pointed this thing at the Dogs and they recoil and stay well clear of me. I have only had to use it four or five times. They stay away, and it stays in my pocket. No one knows I have it. It may or may not work for you. For me, it has done what I wanted/expected.

I've tried cheap batteries and expensive batteries and there is a difference in this type of device. Niteize sells replacement batteries that seem to last about 6-8 weeks with a daily 15-30 minute walk (usage). With the cheap batteries I was experiencing two weeks and they would go dead. Bottom line, you get what you pay for. As another response stated,you simply pry the back plastic off to gain access to the batteries - each device requires two batteries.

Its a pretty long time. I charge it occasionally, but it has never died on me while I was using it.

I have been using the device for two months only and very few times until it dies. The longer I have experiencie is almost 7 hours. I hope this is useful

If you mean continuous usage I have had one last about 8 hours. The great thing though is the unit has another battery charging in the base and you can easily slip one out of the unit and slip the charged battery into it from the base unit in about 30 seconds or less. The battery re-charges in the base in an hour or so and you are ready to go again. This unit has such a better design than TV Ears I could not believe I wasted my money on TV Ears for 4 years before I found these.

4 to 5 hours I believe... depends on what your doing with them, constant music shorter battery life...

the battery life lasts approx 4-8 hours...sometimes longer if not used continuously.

Most batteries last 4-5 days depending on how many hours you have them on each day.

On a set of batteries? Probably, I would say 8 hours. It's not very loud. It's good for home use.

Battery charge lasts about 5 to 6 hours. I bought 2 of them and just change to the spare it I am watching that long!I don't worry about the battery life for the price :)

About 48 hrs. My Mother and daughter kept theirs on so they could keep up with each other. When they tried turning them off to save battery power, that seemed to eat up the battery life even faster. They are not using them at all now. It goes through batteries too fast and I still have not been able to find a charger that fits the adapter plug on the side.

Don't know actual battery life on device(never kept track) but probably not going to last long enough for what you want.

I can't give you exact hours but I can tell you that my sons use their players at campouts for many hours and I have never seen them go off. I have never used mine for an extended time on battery.
