how long does the battery last?

I use rechargables, and I've never actually run it out in this one, but it's more than 2 days of straight reading.

Long enough for me! My daughter falls asleep with it on so I have to change the batteries every couple of weeks. I love having four of them!

Can't give exact time but they last pretty good time. They use reg AAA batterys.

it has a pretty good battery life we've had ours for a while and haven't had to replace them yet with occasional use

Hard to say. I use it to light my keyboard when I'm on my computer in the dark. It's lasted me for about 2 months now, but when I use it I usually only use it for up to an hour and I do use it quite often though.

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

Well, it depends how long you keep it on. In general, It lasts at least 9-12 hrs in a day when it's on, but if you use 'sleeping mode', it would be more than one day(at least one and a half day you don't need to charge it). Hope it helps.

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

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.

battery life is good (Haven't done an exact measurement, but it seems like I recharge about every 3 or 4 days). It has an automatic sleep function that preserves the battery life. Full charge in about 2 hours.

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

I still average about 2-3 hours on mine. I've had in the neighborhood of 15 months. Been a great battery.

I can't say over the long-term, but I have had mine for three months, I use it everyday for hours at a time, and I have not yet had to replace the battery.

it lasts as long as you dont use it. the battery does not lose its charge once it is charged

I don't know exactly how long the battery lasts (it said up to four hours in the book) but I enjoy movies on it in the evening and I never have problems with the battery running down. I have worked from it in other areas (unplugged) and it certainly keeps me on long enough.

Quite a while. I have owned this for well over a year now, and I have only replaced the batteries once.

I haven't actually timed it, but I've been able to use it quite a bit without recharging. I use quite a lot on Sundays and for hours at a time on other days of the week. Takes several days before I have to recharge. I have been impressed with the battery life.

2.5 hours is a long time. I have to keep mine plugged in constantly. The battery is terrible on this thing. After 6 months of use its even worse.

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.

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.

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.
