How long does the battery last on high?

As another poster said, the low setting is blinding. Why do you need the high setting? Never mind, that is a rhetorical question. I am using it for about a month now, and I have not even recharged it once...

At least 1.5 hours on high, but over 2.5 on low. This light is blinding even on low. I glued some diffuser film to the face of the frame with instant glue to remove the mild hot (bright) spots. It turns night into day. Buy the second battery if you are going long. Warning -This light (LEDs) just shut off without warning when the battery is discharged. Usually at the worst time.

I have only used on high for several rides, but has always lasted at least 90 minutes on high.

I have had 1hr 15 mins out of it. You do need to leave it on charge until you need it. Even leaving it off-charge over night reduces the burn time.

Mine ran 2 hours 40 minutes on high today. Down to one indicator 20 min before end, flashing indicator 5 min before end.

When it is fully charged, it lasts about a week, and then the battery loses one bar. I presume it can go a month and be just about ready to "die." It never actually "turns off" otherwise--the clock display is always on. But this is just in standby mode, without using the features.

I just used mine for 6 straight hours, and 2 hours the day before, still going strong. I would estimate 10 hours full charge to dead.

At least three months of heavy use. No warning of the batteries dying yet either. You don't have to turn it off and on. It will turn itself off after roughly 10-15 minutes of being still and takes about a second to turn back on by moving it around. It's quite good, and probably even better with rechargeable batteries.

Iʻve found that if I have it on high speed my battery only lasts 30-40 minutes. On lower speed it may last an hour. Iʻve also found that if I donʻt turn it on and off when moving from place to place, it lasts longer. Hope this helps.

I don't know, there was some charge on the battery when I received it, and I plugged it in and left it, I don't think it took that long. Since then it didn't take long to top off the charge since I hadn't used it yet.

I have charged the battery maybe 4 times now. I would say it lasts for a good 6-8 hours of on and being used time.

Are you asking when it stops down (like 3 minutes), or when it runs out of batteries on high?

Sorry about the delayed answer. . . 3 hours on high beam is what my owners manual specs say, and 97 hours on lowest setting. I assume this is with the 18650 rechargeable battery and not on the AAA batteries. Hope this helps.. .

From what I can tell so far, when running continuous on high, the battery only last around an hour. But that probably isnt real accurate. My uses are on and off a lot. I dont usually run it for more than a few minutes at a time. I do know that this light does get hot to the touch when its been on for an extended period of time.

I never let my battery die completely, but I would say it lasts on my laptop about 4 hours.

With setting on "high", it held it's charge for a good 3 to 4 hours. I know it can last longer with high quality alkaline batteries.

6 minutes in "Max" mode. It will last longer in regular mode (about 20 min), but the vacuum really doesn't pick up well unless in Max mode - so realistically the battery lasts 6 minutes.

That completely depends on the speed you are running it. If you only run it at full speed, it may last two hours on a charged battery. If you run at the lowest speed, it can last up to 15 hours or so.

I use mine on high 30 to 44 min every morning. I charge it every 3 or 4 days. I have never ran it dry. love the light its very bright for the price. would recommend it to any one.

I have had mine for a couple of years. It does stay on for more than 4 hours. Unless they improved the battery draumatically you will not get 6 - 8 hours.

On a full charge, and, for me, I had it on the third setting (Blue) on constantly, onto my iPod, it last around 6 hours! So, if you want to run it for a long time. Quick charge during lunch breaks, coffee breaks, and so on.
