Hi there, the included battery lasts approximately 3 hours on high, 5 hours on medium, and 8+ hours on low. After these points the light intensity will drop significantly but will still run for several hours before going out completely.

I haven't tried to run it all the way down since the laptop is usually stationery except if I move around the house with it but I know will last at least 35-40 minutes and not still had around half battery according the battery meter on the taskbar. This is the 2nd battery I have purchased. The 1st one was for a laptop for my mom a while ago and it's still working but again that laptop is not used that much off house power. For $20 bucks I'm satisfied

No actually the battery life is pretty good. When it's fully charged I would use it for about 3-4 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.

I've had it for about two years now, and the battery life on it is about two hours, give or take. It's definitely better than the one I replaced, though. I'm still a little disappointed that I have to practically keep my laptop plugged in just to be able to use it for longer periods. Hope this helps!

I can't say that I've check on the battery life. It seems to last pretty long. I will check this week and try to repost.

It actually has it's own built in battery. It lasts about 5-6 hours, which isn't too shabby.

My $15 version is sealed also. Even with the display on continuously, the estimated battery life is 4 to 5 years. I plan to simply buy a new, improved version when that happens. There may be a more expensive version with a replaceable battery.

I've been testing mine out recently - I run for about 2hours, 2hours 15 mins. It usually lasts 2 such days - so 4- 4 1/2 hours- which is quite disappointing. I have a feeling indoor battery life maybe slightly better. I was looking for the "rated" battery like myself. Would be nicer if it went a week without charge.

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.

I've had mine installed for just under 60 days and the battery life still boasts duration until 2020. That's with all "senses" in use. Assuming that's accurate information, that would be awesome.

I got this on Aug 2013, and now it is only 6 monthes or so, and I use it not daily, but once--weekly, so the battery is still good, not 30mins, over 1 hr no problem. never measure it.

The battery life is pretty good and lasts a while and the battery is rechargeab. Hope that helps :)

Actually, my first full charge took almost 48 hours. I initially thought the battery was defective. However, every charge after the first one has been relatively "normal" (4 hours or so for a fully depleted battery). I'm very pleased with the battery's performance. It lasts for slightly over 48 hours with GPS, Wi-FI, and Bluetooth turned on; and normal call/text/surfing use.

Very long. I can sometimes get into some lengthy gaming marathons, and the battery has never been an issue. I estimate 4-6 hours depending on volume and battery health. Also note that you can use the device while it is charging, but the included cable is too short. If this is a major concern consider purchasing a longer USB cable with a Micro-B termination on one end.

The battery last longer but takes the same amount of time to charge. I think that it's what you where asking, if not let me know and i'll try to get a better answer for you.

With installed 800mA battery, after 100% charged, it last about 3 days. We had a test on a 2400mA battery, it last about 7 days.
