how long do batteries last

It depends on temperature and frequency of activation. I'm in NY and it's' been very cold. After about 2 months the units performance became erratic. Just replaced the batteries and it's working well in the snow and fridgid temps. Keeping the dogs away.

The repeller is motion activated, so battery life seems to be long. I'm still on the first set of batteries, and it's been a couple of months so far.

A few weeks. Yes, they don't last that long. BUT this is a very good unit. I know it's working in my yard.

The batteries will last approximately two years when in standby mode. If the alarm is sounding continuously, the batteries will last approximately five hours. With normal use the alarm will not constantly be in standby mode or sounding continuously. Therefore, the user can expect the batteries to last anywhere from 3-12 months depending on how often the alarm is activated.

The first set of Duracell batteries in one light on our front porch (activated a few times a night on average) lasted for four years. I had to replace them earlier this year so i don't know how long these second set will last.

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

They last quite a while. I mainly use them for my son's wireless remote for his Xbox 360, he plays everyday, somedays he plays allday and on average we usually have to recharge them every 3-4 months. I found them to be better than an OEM battery we've had.

It lasts quite a while. I don't use mine much but I have only put one set of batteries in.

I had one set of batteries last about 3 months.. the second one was still going at around 5 months when I took it off the wall.

I have used mine for at least 4 hours. After 6 or 7 years it still lasts over 2 hours.

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

On the higher setting, they probably lasted around 18-24 hours. On the lower setting, you could probably expect 24-36. We used them in Haiti and were pretty pleased with their performance. Ended up using half of the batteries that I expected to.

Guess I cant really answer that question. I put 6 D rechargables in it and have several fishing trips in with and it still has'nt used up the batteries, so its a long time. I would say I have over 24 hours of use on them and still going strong.

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.

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.

Usually the battery last between 4 to 6 hours. Just make sure you don't drain the battery. When you see that the battery is almost gone, charge it to prolong the battery life.

I'm still using the batteries that came with my chainsaw, my tree-trimmer and my weedeater. I made sure to buy items that all ran on the same batteries. I think my oldest battery is 3-4 yrs old. I did lose one because I dropped it on concrete. I am just now reaching the point where I need to replace my batteries. I use them year-round. I keep the charging all the time so on evenings or weekends I always have batteries to go. My batteries still work but it seems they don't hold a charge as long. So I would say 3 to 4 years.

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 use my lamp on and off for a week or two before changing batteries. If used steadily they would last somewhere from 6 to 10 hours I'm guessing before changing batteries but I'm using rechargeables. They dim steadily when the batteries loose charge. It's the best clamp lamp I've ever had and withstands heavy use. Very sturdy.
