We're going on four months so far and no issues. We are using Eneloop rechargeables and use it appr. Twice daily for 30 minutes to 3 hours.

I suppose it would depend on how often and how long you use it. Also what kind of batteries you buy. We use ours often, and sometimes for a long time, and I've only had to replace them once, after about 2 months. You might even consider rechargeable batteries, and have an extra set ready to go. Save a bit that way.

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.

Greetings. Theoretically speaking, the batteries can last 100-120 hours. But it will also be affected by the battery type and usage. Thanks for your question.

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.

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.

About a good 6 hours maybe 8...I bought them as a Christmas gift for my two kids and to be honest I don't allow them on longer than an hour but my husband used it for 6 hours straight. Pretty good product I honestly can't complain.

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

Not long, had to buy an extra 3 pack of batteries to keep on hand. Never leave home without an extra one.

Wel we don't run the lights all the time so I only know that I have only changed the batteries once so far. We run them when we have guests over. It appears that they last pretty long though.

My battery last for a while. About 2-3 months, but I think it depends on how much it has to be used. The batteries are cheap at Walmart.

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.

We have had six of these units in our home for over a year. We replaced all batteries after approximately one year. One unit is outside in the cold and heat and it's batteries lasted a year. The unit will give a little chime note every three or four minutes when the batteries need to be replaced.

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.

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

Quite a while. I have owned this for well over a year now, and I have only replaced the batteries once.

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
