How long do the batteries last?

If you get good batteries, will last at lest a few weeks. Also depends on what kind of surface you are running the tank on. IE thick carpet and doing a lot of turns, hard floor etc. I am happy with battery life.

I use the light for 1 to 2 hers at a time during orchestra rehearsals 1 night per week and church services on Sunday mornings. 1 set of batteries has lasted for about 3 months and I just had to replace them. I think the info that came with the light said they should last about 10 hours of continuous use.

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've never replaced the batteries. We've had it at least 3 years if not longer.

My experience is that the batteries last approx. 4-5 hours. I use mine for work and I love it. Problem is I found the exact light at a boot store a month after my purchase from Amazon for only $4.95!!!!!

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

I use the Duracell AA batteries and I believe it takes 16 total. They last quite a while depending on usage.

I am going to say probably 4-5 hours on average if they get a good charge during the day. I now need to replace the battery in one of them, but I have had them for about 4 months. The others I have are still going strong.

Thanks. How many batteries? According to your experiences, do they last for 7 months as expected?

I put new batteries in last year after I first installed the lights. I am still using the same batteries. Usually I leave mine on for about 2 hours at a time. I've probably used mine 6-7 times so far with the same batteries.

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.

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

I fall asleep with them on, and the charge lasts at least eight hours with the volume on a low setting. I have never left them on longer than that, and I recharge them each morning.

Really couldn't say - I use these infrequently. I will use them nightly for a week or two, then turn them off. Only use them on dark winter evenings. Still using the batteries from last year, therefore. So - I will hazard a guess that they last a long time, maybe several months if not used daily.

We have been using ours since at least June of last year & the battery has not died yet. So they last a long time.

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

I haven't timed them. I use it for about 10 or 15 minutes per day, and I have to change the batteries on average once a month.
