How long dose last the batteries

Depends on your light (LED vs Incasescent), the lumens, and use... Could range from 180+ hours with a 15-20 lumen LED to just 2-3 hours with a 120 lumen incandescent. Check out the lumens factory message board for more details...

It really depends on your personal use. My husband uses his to go hunting to get in & out of blinds, tracking blood trails, etc. I use mine just when I need it and they last a long time for me.

I have not timed it but it is way less than a regular flashlight. I have a bright surefire flashlight that I use at night when I take the dogs out. But off hand I'd say monthly they need changing.

It depends on what you're using it in . Some flashlights will use them up in 20 minutes others will last for 10 hours or more

depends on what the use is and the time you use it they are the best batteries I have ever used

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

I have had mine for 3 months and have used it once or twice a day since then. I just changed the batteries in it today. So depending on you use I would say 2 to 3 months.

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.

About a half hour. Then the charge lasts about 10 minutes. Purchase multiple batteries!

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

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.

A very long time. I would say somewhere around 30 hours. The battery lasts forever though.

Regular batteries (AA I think) and they last a pretty long time. I've had my first set about two years now and maybe have replaced batteries once, maybe twice. Wear them an average of 9 -12 hours a week.

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.

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

Sorry I missed this. My wife uses it and says she has 8-20 hrs and still the same batteries. Said she loves it though !! Hope it helps

If I recall correctly they take AA batteries. The battery life would depend on the batteries, I guess. We don't use them for very long at a time so I am sorry I cannot be of much help.

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

Thanks. How many batteries? According to your experiences, do they last for 7 months as expected?

I personally do not knwo as I used them for a teaching aid in a project but depending on what batteries you use they can last anywhere from 24-48 hours continuous (LEDs on). The consumption on it in standby mode is very little (~70 micro Ah) so depending on if it is placed in a high volume traffic area or not will also determine how fast the batteries deplete. The consumption when it is on and lite is ~70 mAh.

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.
