How long do the batteries last with daily use? The specs say 10 hours on average but I am not sure how to quantify that.

I've had one for a few months and use it every day with no issues. I've had similar products before and the batteries last for years. If you think about it these work the exact same way your car remote does, and those batteries last several years with daily use.

I love this thing. Had it for a while and haven't replaced the battery. You should be fine for months

I wish I could answer your question. I only kept the machine for about a week. I did use it with the batteries for about 8 hours each night. As far as long term life of the batteries in the unit, I am not able to answer. Sorry, I am not much help.

don't really know. I have an average size battery, fish for 2-3 hours, have never run down the battery.

Can't just answer that without a few considerations. Our experience was easily a couple hours, depends on how fast you run it and how it's used. As the batteries get older, that time will shrink a bit, as all batteries do normally. We were thinking and I think it would go longer for sure. Hope that helped.

4 to 5 hours I believe... depends on what your doing with them, constant music shorter battery life...

I get about 6-10 hours depending on how I am using it. If you use it for longer periods for listening to music its closer to 6. But if you are using it more as a way to answer the phone, then its up into the 10 and beyond. I love mine. If the battery life was longer it would be perfect.

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

I have had mine on about 12 hours of use. Still have the factory batteries in it. The camera batteries going dead is the problem I run into when do time lapses.

I've had mine for almost two years and have changed the battery once. Over a year on the current battery. About 7 hours a day average browsing use.

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.

In standbys or light use such as occasionally checking emails and answering phone calls the charge last me all day (14hrs). I get that with the original battery also. It is important to note that it took about 3 charging cycles to get this performance. Out of the box after original charge I only got 8 hrs, but in my case performance improved after more use. Heavy use gets me about 6-8 hrs depending on what I am doing.

I didn't do any scientific measurement. My opnion is therefore subjecive. It appears that these batteries do last. This key is to get them fresh. Batteries do lose power with time if you let them sit. Some lithium button batteries that I purchased on e-bay were two years old and lasted about a week in my guitar tuner, which is way too short. I blame it on the age of the batteries. Those 9 volt lithium batteries don't seem to have this issue. We'll see in a few years.

My experience is that the batteries last approx. 4-5 hours. I use mine for work and I love it. Problem is I found the exact light at a boot store a month after my purchase from Amazon for only $4.95!!!!!

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

Where did you hear that? Of course not. I use mine daily and it usually lasts for 2-3 days based on my reading, web surfing and emailing activity. I let the battery completely run down after I first charged it and it lasted almost 11 hours. On average I get at least 10 hours of active use on it, but I usually charge it every three days.

Carol,I've had no issues with my batteries. I bought a second more inexpensive one (different brand) also without any issues. Sometimes I get as much as 8-10 hours. Hope that helps.Ed

Batteries last according to power consumption of usage. Anywhere from 1hr to 3 hrs depending on what your doing. Keep in mind that Core i7 processors draw more power when used at high percentage than most other processors.
