how long do batteries last

I have only had mine for 3 months and wild animals around my place set it off a lot but batteries are still going strong where as my Radio Shack alert system(cheaper) would only last a month. Very pleased with these.,

Mine last at least 6 months, but a couple have lasted close to a year. It depends on the battery, weather, and how much traffic you have to trigger the alarm. The lithium 9 volt batteries do not work correctly because the voltage is too high and it causes lots of false alarms. Hope this helps.

Do not change batteries enough for it to be a problem. Probably depends on the brand. Maybe once a year

I have used mine 8-9 times each time was about 30-45 minutes. I have not replaced the batteries yet, but I do keep an extra set in my truck. I use lithium, due to the cold weather.

My batteries like these (I have a few) have lasted well over a year. Average with daily use has been a year and half and more.

One or two hours at most. The worst thing is to run them all the way down, then put on the charger and forget about them. If you will look on Amazon. Under some or the batteries, they give you the do's and don't of how to get the most life out of your batteries.

I had fantastic luck with regular double A batteries as well. Generally, they would last for maybe about 8 hours of life, and I always got accurate battery life readouts, and was always able to replace them when they got low without any issues.

The rechargeable batteries last about 8 hours of continuous play. They are great for travel. Regular AA batteries might last 3-4 hrs of continuous play.

I kept them on 24/7 as part as a door decoration, and the batteries lasted about a week. They were cheaper batteries though. But I would imagine you might need to replace them once or twice to last all season. Beautiful lights though!!

Depends on how you [ab]use them. If you often run them all the way down, and/or run them down only 1 or 2% and back up to 100%, they may last less than a year (or only take half a charge after a while). If you seldom run them below 30%, and don't recharge until they're 90% or less, they may last 5 years or more.

I had read somewhere online that people had the batteries last 30days. I found that after 48hrs the motion detection started to be significantly less sensitive until I put fresh ones in again.

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

I do not have an exact time that the batteries last. I can tell you that I've used it numerous times and haven't really had any issues with battery life.

I've got this same set on my bike and I use rechargeable batteries in mine. They usually last about a month to a month 1/2 before having to be recharged. I've been using the same batteries since I got this set of lights about 4 years ago.

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.

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.

depends on the batteries you use... I guess. but mine last for about half a year

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

Can't give exact time but they last pretty good time. They use reg AAA batterys.
