How long do the batteries last?

I've had them a month and have used them for hours at a time and they are still working. I didn't think they were gonna last this long to be honest. They take watch batteries in case you were wondering.

On the higher setting, they probably lasted around 18-24 hours. On the lower setting, you could probably expect 24-36. We used them in Haiti and were pretty pleased with their performance. Ended up using half of the batteries that I expected to.

I cannot answer that fully. I have not left them on long enough for them to lose charge. I have the manual at home. So I would guestimate 15 hrs? Maybe more, maybe less. Best bet is the manual, what it says, but if you don'g actively correct them for a long period I would think it would hold charge a little longer

Not sure. I used it for a week, a few hours almost every night. I have yet to change the batteries since I got it.

It' hard to say but I have had them last 24 hours on standby. With use and time as with all batteries it seems they develop memory and lose their capability to maintain a charge over a long period of time. I carry two batteries with me and switch them. From the beginning of my day until about 4 o'clock I usually have to change batteries or put it on charge.

Batteries will last 20 to 40 hours depending on factors such as quality of batteries and if headphones are being used to save power.

I use them alot , most of the day in fact, and I can get around 5 hours (talking on Skype and listening to Youtube videos) of use out of them before they need recharged. They take about a hour to recharge ( I just use them with the charging cord plugged in)

Two double A batteries, and they last about 30 hours. I walk an hour a day, and change the batteries once a month. Sorry it took me so long to get back to you.

Regular batteries (AA I think) and they last a pretty long time. I've had my first set about two years now and maybe have replaced batteries once, maybe twice. Wear them an average of 9 -12 hours a week.

Not long. about 15 mins. of run time. I bought a second battery so i could easily swap them out and keep going.

Hard to say because I only turn them on when I'm taking them out for potty time at our lake house. I can say that one of them got stuck on and I had to remove the battery to turn it off. If you look around online you can find batteries for these pretty cheap. Overall they are not super high quality but do pretty well.

Depends on use. We used ours for 2 nights(all night long) before we replaced batteries. We used cheap batteries

I can't tell you how many hours but I've had mine since May of last year and have only changed the batteries once. I have them on every night from about 7 to 12.

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

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

They will last all night and probably 2 to 3 nights. They are powered by three 1.5 volt lithium batteries and can get pricey. However, they are nice and soothing. They contiuously change colors

Can't give exact time but they last pretty good time. They use reg AAA batterys.
