I don't know how long the battery lasts. I didn't use it much and I got a $3,000 hearing aid before the first battery was done.

I have not used batteries in my unit yet. I have seen in some reviews that the batteries don't last too long.

I am not qualified to say how long the batteries will last based on your description but would assume based on my past experience that they will have a fairly long life compared to other style batteries. Unfortunately they are not rechargeable.

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.

Don't bother. The batteries last a week. Maybe. Without ever turning them on. Have tried several batteries and even exchanging. I would turn them on once for 5 minutes, turn it off. Come back a few days later and they don't turn on and need new batteries.

I've had them HOLD there charge for 4 months of non use! up to 2 months of off and on use and for at the irish fest shooting and video taping 2 - 4 hours depending on how hard I'm going They do hold up well I cannot complain! Those batteries that only cost a few dollares and ya I've tried them! NO.....don't hold the charge for long and don't last that long either. I've had the cheapies go in 2 - 3 years you know freshly charged and Dead in 30 min.

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

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

Not long at all. I had to stop using mine. When you put batteries in you get about 8-9 good hours, then light begins to dim. It is worthless!!

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 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.

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.

Yes, I was actually surprised the batteries lasted a month. Figured they'd get used up fast but not in this case. Really works too. Hope this helps.

the battery life lasts approx 4-8 hours...sometimes longer if not used continuously.

I wish I could answer your question. I only kept the machine for about a week. I did use it with the batteries for about 8 hours each night. As far as long term life of the batteries in the unit, I am not able to answer. Sorry, I am not much help.

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.

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