Depends on what programs you are running. But I usually get 4 hrs out of mine as a college student.

Lenovo rates it up to 6 hours (idle, dimmed screen, etc). Real world usage is probably around 4-4.5 hours.

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.

The most I have had battery life is a little over 2 hrs. If you charge it and don't use it right away it will die. But honestly for the money its a good price. Hope this helps.

Not long at all. Maybe 30 min from a completely dead battery. Lasts a good while too.

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 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 might not have understood your question, in that you want the time a battery will last, once charged (hours)? Since I turn my computer off and on there is no way that I can tell how many hours I get on a complete charge, couldn't even guess.

It' hard to say but I have had them last 24 hours on standby. With use and time as with all batteries it seems they develop memory and lose their capability to maintain a charge over a long period of time. I carry two batteries with me and switch them. From the beginning of my day until about 4 o'clock I usually have to change batteries or put it on charge.

I have charged the battery maybe 4 times now. I would say it lasts for a good 6-8 hours of on and being used time.

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.

My batteries like these (I have a few) have lasted well over a year. Average with daily use has been a year and half and more.

A very long time. I would say somewhere around 30 hours. The battery lasts forever though.

You can't ask such a basic question like "how long does the battery last"... there are so many factors.How fast your CPU is set to run. LCD on time. HDD spindown time. WIFI being used...The best way is to CHECK the battery with "BATTERYINFOVIEW" from google.Once you get the "designed capacity" from the program, you can calculate the TRUE capacity in MAH which will give you a more accurate representation of how long the battery will last compared to a stock battery.

they last pretty long for me. It really depends on the type of item your using these batteries for. But for me they always last at least 5 hours. Theyre pretty reliable for me. They also take like a day to fully recharge for me, i go to sleep & when i wake up their fully charged.

I use it on the bus to work, my commute is short about 45 min.; the battery last for about 4 days. After using the on, off, volume up/down etc. for a period of time, the printed data dissolve.

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.

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.
