How long do the batteries last?

We have only used it as a corded appliance. Never had to rely on the batteries. So sorry, but we love the machine, makes sleeping much easier, and in an apartment, is indispensable!

Never used ours on the batteries. We have it placed close to a plug in at home.

I do not know exactly, but I am going to say at least two years. They rarely need changed. Battery life is impressive.

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

The batteries so far have lasted for 7 to 8 showers. Not long ones and I did not change the batteries yet since I bought it.

Hi there....I can't say exactly how long the batteries last, but I do know that we went to Haiti and ran two of them ALL night while we slept for one week, and never changed the batteries. Hope that helps.

Well we have had them for almost 2 weeks and one has never been turned off and is still going strong. We haven't used them as much as we thought though. So even though the batteries have not died with it being on I still wouldn't be able to tell you how long they last if you're using them consistently. Overall I would say they conserve the batteries well.

Pretty long. Months I would say. We got ours about 10 months ago and I think I have only replaced the batteries 2 or 3 times. Pretty good considering it is used almost every night.

Yes, batteries last around 6-8 months. Two AA-'s in the motion sensor and the speaker plugs into a wall outlet.

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

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.

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

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

They are 'D' batteries . They last long enough. Still like radio. Its a very simple radio.

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 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.

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.
