4x 18650 cells may last 5 hours in low. Used about 2 hours in low, still bright.

I used it out in the field while hunting, very bright and if constantly on, lasted one full hour. If used off and on, went one week between charges. Hope this helps, great unit and want the next size unit.

I use it on patrol and usually recharge it once a week. I have had the combination of the ultra fire rechargeable batteries as well as the flashlight for over a year and it works great.

In low mode one gets much longer battery life due to the fact it is only supplying 275lumens light output; which most of the time is still a very intense bright white light; yet at the same time it only has use only about twenty percent of the total power one normally uses when on the highest mode setting; this is usually an acceptable compromise in real life primarily because of how our eyes work and this also allows one to extend and save on the normal inevitable wear and tear on ones lithium ion batteries over time also as well.

Mine came with rechargeable batteries. I have never let them completely run down but when the lights on its brightest setting you can start to the the beginning to get a bit dimmer in about 15 minutes. Then I just recharge and go again. I hope this helps. Oh and it is very very bright!

I imagine it depends on the power drain of the particular brand of aids that you have. I have Phonaks, and the batteries typically last about 3 days.

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

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.

I just plug the batteries in for around 8 hours and use em. It works well for me. I hope this helps. I had also purchased new batteries and I charged them overnight the first time. GOOD LUCK

It would depend on the batteries that you put in and how long you let it run.

Depends on the quality of the batteries I used cheap ones almost apnth the good ones about six months energizer or Duracell

A long time. They are built really good. Now the problem you will have is the battery. For long storage take the battery out of the housing. Keep it Dry and you should be able to use many times. I suggest you buy some extras batteries.

I bought about 16 of these for our smoke detectors because I am so tired of them quitting on me after a year; the batteries were within the year so I am comfortable I will get close to eight years; and at this point if I can get 3-5 years, I will be ecstatic. I hope this answers your question.

Part of this answer is going to depend on the quality of battery you buy. here is my experience. I used Energizer batterys for the week of my vacation. The radio was on for about three to five hours for five days (20 hours or so) When I got home I took the batterys out and went back to using the cord because the radio stays in the house. i tested the batteries and they still showed an almost full charge so I put them with my spare flashlights. I would guess that the batterys would have lasted better than twice the time I used them for.

Depends on the strength of the charging supply. A couple hours. I do them overnight.

The batteries for the lawmate PV900FHD should last approx. 2 hours I haven't run mine until it has died yet though.

No the battries are item specific. however tbey are rechargeable and last a fair amount of time per charge.

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

That's a very good question, I wanted the answer to that exact question. The answer is "NO" it dosn't, however, it takes two AAA batts which I thought would deplete quickley, that's not the case, I'm still using the first set I installed, nothing special, regular life batts. so far (6 mos or so) 10's of hours of use, works well every time. I really like this thing!

The expected life span of these batteries is approx. 1 year give or take a few months. My last set lasted 2 years

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