how long is the battery last?

The battery is pretty long-lasting. I don't know how many hours you can get out of it, but I use it as a modeling light with my speed light flash, and after using it continuously for 3 hours, it still has a good deal of oomph left. No noticeable weakening of the beam. The only thing to remember is that the battery dies quickly when it starts weakening. I think this is the best light I've ever bought -- nice and bright, and plenty long-lasting.

I don't use it all the time like everyday but I have purchase 6 of them for me and family members and we love them. Best purchase

I have not actually "test" how long a full changed battery can last. But after I used it for nightly walk several times a week ( not on for all the walk, only a few minutes per walk, but when it's on it is with full brightness ) about three months later I found the brightness is weakening. I know it is not a very scientific way of "testing", but that's what I know about the battery. It is decent but not great as far as battery usage goes. Hope it helps.

There's a rechargable battery. It lasts a long time. I think it says 10 hours.

I would guess several hours, I didn't keep it in constantly after a charge, but using it 20-50 minutes at a time a few times a week, it lasted over a month for me.

I'd say mine lasts just under 3 hours at the lowest power levels. The battery is easy to remove, so you can always buy a second battery to double your life.

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.

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

Usually the battery last between 4 to 6 hours. Just make sure you don't drain the battery. When you see that the battery is almost gone, charge it to prolong the battery life.

I do not have an exact time that the batteries last. I can tell you that I've used it numerous times and haven't really had any issues with battery life.

I've never had mine die on me but I've taken it for a six hour trip and it had about 25% battery power afterwards so I'd guess maybe about eight hours in total.

My battery last for a while. About 2-3 months, but I think it depends on how much it has to be used. The batteries are cheap at Walmart.

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 hard to say but I leave mine on charge the day prior to using for a period of time. I can get about 7hrs playtime.

If you leave it on constantly then probably only 1 day it's a tiny battery. but if you only use it a couple hours a day it will last.

I have run it for about 6 hrs before on a fully charged battery. Sometimes 7 depending on how often it is used. I keep a spare fully charged battery on hand just in case.

About 6 - 8 hours if you run the battery all the way down. Which I dont recommend because your batteries wont last very long.

It only lasts a 2 - 2 1/2 hours MAX for me. And I have my computer on the settings to maximize the battery life. Very disappointing.

I haven't timed it but, I would say hours. It blinks on and off when the battery gets low so you aren't surprised when it goes off
