how long does the battery last?

I'm not sure if there is some confusion regarding how it is powered but I don't want to seem like a jackass but it depends. Unit is powered by 4 "AA" batteries (not included), if you use high powered batteries I think you could get 6-12 hours of use at moderate volume. If you use cheap batteries at high volume maybe 3-6 hours, again depends. Friend I bought it for uses the AC adapter, when we used it with batteries (standard alkaline) it lasted 2+ hours without dying, I hope this helps.

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

The battery lasts around 3-4 hours fully charged. I found it very useful to keep it plugged in while using it at home.

Pretty long. Months I would say. We got ours about 10 months ago and I think I have only replaced the batteries 2 or 3 times. Pretty good considering it is used almost every night.

Hi,I have mine since two years ago, the battery had a duration between 2 and 3 hours, but since one year ago it last around 30-45 min.

Less than 4 hours for mine. The battery really does last a long time. I've had mine for several months and use them for up to 4 hours or more at a time, a couple of days a week. I have only had to charge them a couple of times so far. I am impressed with the battery in these.

I tend to keep mine on power save, it seems to last pretty well. I'm not sure and exact answer on a number but several hours.

the battery works quite well. it lasts at least one to two days if you consistently use it. although its off for a while, you still can turn it on without losing power not being used.

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.

The battery will last for 10 hours, but only when kept at a moderate volume. If you crank the volume up near max, the battery will last about 5 hours.

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.

Battery life is pretty good... A whole day if your actually using it.. I've left it sitting and it's lasted around 3 weeks without usage on one charge.

Not long. about 15 mins. of run time. I bought a second battery so i could easily swap them out and keep going.

I can't say I have ever measured the battery life but we are happy with it. As long as it was plugged in overnight, it usually makes it through the day, because we set it to suspend after 15 minutes of idle time and we rarely use it for more than 30 min straight. If I ever take it with me to work somewhere for an extended period, I just take the cord with me, it is pretty light.

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.

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'm not sure. I keep it plugged in. Sorry I can't be much help regarding the battery life.
