How long do the batteries last?

I have had mine for over 2 years and the batteries are still working, in four different units.

I don't know yet, because I am still having troubles connecting it to my VERA 3 home automation system.

No idea 2years and counting. Works very well provide a solution to a near impossible wiring task. Good luck

I have had mine for over a year, it controls two lights that are used daily, I replaced the batteries only once.

I've had this in and working for over 2 years now and haven't needed to swap out the batteries yet. It shuts itself down when not in use, so it will not relay Z-Wave messages, but that helps keep its batteries from draining.

depends on your weight. 3 or 4 hours for me when batteries were new, but unit is cheaply made and doesn't last long.

They come with batteries. Not sure how many because I've never had to replace them yet.

It says on the box that the batteries last up to 55 hours. I would assume that is on the low setting. Other than that, I am not sure how long they would last on high. My daughter uses one of these for weekend camping trips and says they last a good while, but she has never paid attention to how long in hours.

9 to 10 hours depending on setting and batteries used. I usually get at least 9 hours using rechargeable batteries.

it depends on how long you play it, but most of the time the batteries last for about 2 to 3 weeks. It also depends on the type of batteries you buy.

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 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.

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

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

The rechargeable batteries in mine last about 8 hours on a full charge with the radio playing. When I use alkaline batteries I get about 20 hours of play time.

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

It takes 2 C Batteries, they last a long time, we just go to the dollar store and buy them, last 3 to 5 days.

I have four of these, all installed since 9/2013. One of the batteries died after about 6 months, which kinda worried me, but the other three are still on the original batteries and still sound loudly when tested. So, 6 months to at least 17 months. These are nice little units, worth a few extra bucks for the small form factor.

We usually don't use ours for more than 90 minutes of continuous use. They could probably hit 2 1/2 hours with a decent battery, but it might be a stretch. I don't know if you need them to run continuously for the whole time, but we try to conserve power by turning them off when not actively in use. We're running them on Energizer rechargables.

I haven't exactly timed it and as one who has multiple batteries, I don't may that close attention and I don't run them all the way down...but I'd say about 30 mins on average.

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.
