How long do the batteries last?

Not sure I changed mine after six months as I do the smoke detectors. The batteries and the chime were working well, just my way of doing things.

My dad has has it for about 6 months and the batteries are still good. The chime part doesn't do that much unless someone rings the bell. With the large batteries in it I expect it to last a very long time. The transmitter part doesn't require batteries

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.

Depends on what kind of batteries you are using. I have two on my light. They seem to last about 2.5 to 3 hours before I need to change them out.

They last pretty long. Make sure you use quality batteries, like Duracell or Energizer. Don't forget to turn them off when not in use. I don't want to attempt to guesstimate how many hours, but we really don't have to change them often. If they start making funny noises, time to change batteries.

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.

These are not designed for continuous lighting, but for intermittent and for a couple hours at a time. If left on continuously, the batteries will last around 25 to 30 hours. These had been considered for a commercial display case but were turned down due to having to change the batteries every 3 days.

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.

I've had mine about a month now and I've used them for at least 20-30 hours while in the backyard on battery power. The sound is good, the range I am using is about 50 feet with minimal attenuating materials between (walls, doors, etc). I'm not sure how long the batteries will last. You can probably do the calculations based on average current draw and the capacity of C sized cells.

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.

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

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.

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.

Approximately 8 and sometimes 10 hours if I leave them on and if I buy really good batteries. They are easy to turn off and on to save battery life and easy to change the batteries

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

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.

I can't remember how the batteries are that came with them. I have some of these that are almost three years old and I don't think I've changed them more than twice. I have a few that are almost two years old now and one of them just barely started cherping a month ago. I'd say the battery lasts over a year at least. They last long enough that I haven't given it much thought.

Less than 4 hours for mine. The battery really does last a long time. I've had mine for several months and use them for up to 4 hours or more at a time, a couple of days a week. I have only had to charge them a couple of times so far. I am impressed with the battery in these.
