Anyway to put in a better battey? It really doesn't last 7 hours if you have wi-fi and average brightness. I just took it out and "4 1/2 hours left"

I don't believe you can change the battery but I am surprised by your numbers. I've gotten over 9 hours while driving a projector from the video port for at least half that time. Granted I do dim the display and set the processor to max power savings but even when I run it full out I get at least 4 hours.

The brightness of the screen and activity of the wifi make a big difference. If you have the screen on high and watching youtube it is going to last about 3.5 hours. With the screen brightness low and just messing around reading newspapers online it will last up to 6 hours.

It's last I good amount but not that long really. I mean if you have your brightness all the way up its obvious that the battery will drain faster.

While I have not specifically timed battery life under high or low settings, my observations are that on the high setting, the light lasts on the order of several hours but the brightness decreases fairly early on. The light still provides useable light when the brightness wanes but do not expect the light to be "300 lumens" for more than an hour or two. I do not use the light on the low setting.

Not well the battery last about 2 hours not good for lit room. But it is a good product.

i am not sure..i would guess at least 3 years...As for how long the battery would hold a charge:Depnds on how you use it...I had the wifi on and was playing a 3D game for 2 hours with full display brightness and after 2 hours i had 40% battery left...i got tired of playing so I am not sure how much longer it would last.....you could set the display brightness to 50% if you are just browsing the internet and it may last 3 hours with wifi on.....

That depends on the setting. I've never had it on long enough to go out. I usually use it on the brightest setting and have had it last >90 min without dimming. I believe the manufacturer states that it can last 2 hours on that setting. Lower settings will obviously last longer.

It lasts about two hours on lowest brightness. I have a white MacBook unibody from 2009 so the older model may be sapping the battery a bit.

Seems like it will last all night if you have it in full sunlight during the day. Mine gets less than 6 hours during the day and is still on, though it be dim at 4am.

I ran mine for 2.5 hrs on the brightest mode, just to see what it can do. Didn't see any drop in intensity and still had battery left. How much don't know. My other lights are over $200.00 each so was real impressed with how long it lasted so far.

Depends I have about 3 to 4 hours on batt live at one time, it can be up two 6-7 if you are not using a lot of apps! Some people say 12 hours(hard to believe though.)

Many factors affect battery life. I can usually get 4-5 hours out of it if I am not doing a lot of surfing and I dim my screen as I notice the battery getting low.

Also keep in mind that battery life is shorter the higher the brightness setting.

Thanks for the info. I hope to goodness that the lamp life is not 3,000hrs! I've been waiting years to buy a projector that doesn't require rip-off bulb replacements. My own HS201 is on a UPS truck at this very moment, waiting to be delivered to my house...

I have owned mine since the beginning of November 2014, and by the middle of December 2014, the light burned out. It also won't hold a charge. Without being able to replace the bulb and/or the batteries, I wish I'd purchased a different model. If the light lasted and the charge held, this would be 100% Awesome!!! (BIG IF)

It's not my favorite flash light, try loading the battery in a different direction. I often need to tap the flashlight to get it working, even with 3 batteries it only last 15min of continuous usage.

I've seen a good 4.5 hours from mine. About a year old at this point. If screen brightness is down and wireless transmitter off, the indicator will show over 6 available.
