how long does the battery last in continues use?

The longest I've continuously run the light on a full battery, at full power, is one hour. Of course, there are multiple batteries that are compatible with this light so you may just want to research the capacity of each battery at the same wattage and you should be able to narrow it down to the most efficient. Hope that is helpful.

Never done a rundown test but I have used it for over an hour without it dying. They have extended batteries as well. Remember, the LED does not come with a battery and it uses Sony batteries. Using the regular battery should get you 1-2 hours and the extended should double that. I rarely use it at full power as well.

I don't typically use it for more than 3 hours or so at a time but it seems to hold a charge when not in use pretty well so I would say 6 hours or more would be fair.

Overall the battery life is good. For a heavy user like me it lasts for 2.5 to 3.5hrs. its good. the only drawback is it has a inbuilt battery. which means its not user replaceable.

I don't have a definite answer for you- but I can say that we took it on a 5.5 hour flight using it on and off throughout the flight and the battery lasted the whole time.

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

30 or so minutes to charge. . With continuous use, it stays charged 4 or 5 hours. Actually I've never had them go dead on me if that means anything

I have had mine for about a month. I always forget to turn it off so I cannot tell you how long the battery lasts because I have not needed to recharge yet.

Usually around 6-8 hours. I've never had the battery die on a full days use.

Battery is supposed to last about 8 hours but can vary depending on volume, etc. I haven't really pushed it that far to see if it will last that long.

It holds a charge for quite a while. We tend to get a solid 6-8 hours of use out of a single charge.

Up to 4 hrs, but it takes awhile to drain the battery. Everyday use for a week and still running in a single charge.

I have used it for 6 hours, and it still had a charge. Don't know average, I charge it after use.

I didn't use it continuously to test the actual running time. But, through the first uses 9when I ran the battery all the way down) I added the times up and it came out to between 4.5 and 5 hours.

From full charge, the battery typically will last 1-1.5 hours with continued usage.

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.

I'm not sure about continuous battery use without plugging it in, but I've only had to replace mine once so far. It definitely lasts a long time!

The battery lasted multiple times of me using this keyboard for several hours. You have to be careful to turn it off when it is done. I haven't had to replace the batteries yet, though, and I have used it maybe 5 times for 2-4 hours each.
