On average how often do the batteries need to be replaced if this is used every night for a full night's sleep (approximately 7-8 hours)?

We use it every night plus naps snd we change the batteries every couple of months. I actually can't remember the last time we changed them!

We use it for nap time as well as nightly for about that long and have only had to replace them about once every 2-3 months.

I can only speak from our experience; my son is 2 months old and we have used it every night since his birth (and sometimes during the day), and have not yet had to change the batteries. :)

I use mine about an hour at a time and can easily use it for 6-7 times over about about a week before I hear the battery low notice.

Haven't really ever timed it maybe(keyword) 6 or 7 hrs, usually i'll let it recharge after it dies when i go to sleep, sorry can't give you a precise time frame.

I would say 6 to 8 hours. I usually have them in the vapor through the night while my kids sleep

Seven minutes, which is average for this size. I'd recommend getting extra batteries.

Good, I assume. I have been using it 8+ hours/ day for 5 dats a week and I've had it over a month now and haven't had to replace the battery yet.

My son uses it at work and he plays it for at least 8 hours straight. However he then charges it each night not that it needs it but "just in case" I hope this helps

Can't say exactly, but around 8 hours. Usually plug it in the night before we use it.

I've had it close to 8 months and use it an average of 5 to 10x per week and have not changed the batteries once.

I don't leave them on all the time but at least 20 to 30 hrs prob more. They are a common size flat battery easy to replace and has like 3 settings of flashing and one solid. My batteries havent ran out yet.

I have only had mine for a few months and never turn it off. My husband has had one for over 2 years, never turns it off, and has never needed to replace the batteries. Supposedly they have a battery life of up to 36 months. Hope this helps.

About 6 - 8 hours if you run the battery all the way down. Which I dont recommend because your batteries wont last very long.

I've had mine for almost two years and have changed the battery once. Over a year on the current battery. About 7 hours a day average browsing use.

varies of course, but I'm told (by mom the user) as long if not longer than the ones sold by the audiologist... sometimes like a week.. (battery removed during sleeping)

I changed the batteries on mine after more than a year of use; the stock batteries were just generic. I haven't changed them again after replacing it with good batteries over a year ago. I use mine about three to four times a week for several hours at a time. Just switch off when you're not using it.

I'd say ours last about 3 weeks, considering it stays on for a half hour at a time and we usually put it on 2-3 times a night it's not too bad but we will probably invest in rechargeable batteries for it. It is a lifesaver though!!!
