how long do the batteries last on full or low power ?

About an hour. I only use that when its needed. It is so bright that it looks like a helicopter light! Normally I don't need that much light. the saver setting is still quite bright as well

Mine have been used over 3 hours and are still strong. Using Energizer batteries.

I typically use the head lamp for 30-45 minutes at a time on high power and will get about 10 hours of run time before noticing a drop off in the light level.

Well we have had them for almost 2 weeks and one has never been turned off and is still going strong. We haven't used them as much as we thought though. So even though the batteries have not died with it being on I still wouldn't be able to tell you how long they last if you're using them consistently. Overall I would say they conserve the batteries well.

After fully charged, a 10% power remaining message at 3 and 1/2 hours, a low power message followed 15 minutes later and shutdown after a total of usage time at 4 hours. I was on several web sites during this time. Hope this helps, it really is a great lab top.

low battery. batteries drain fast if you leave it on all night. better to use timer and it saves the batteries over time.

I find that at full charge the batteries last more than 4 hours. I think it is a great idea to keep a spare charged. Especially if you are editing or taking video as well.

Average Battery Life is about 4 hours. The product description, (That MOST people seem to ignore), is "UP TO 5 Hours." 5 Hour Battery Life IS NOT Guaranteed. On a FULL charge, battery lasts 4 to 4.5 hours.

I charge mine over night and then use till it starts to slow down then over night again. I have forgotten about them in the charger for about three days, they were hot, and over the years it seems to shorten the life of the battery. so 8 or 10 hours for full charge.

It takes 8 hours for both batteries to be fully charged from empty to full. But most of the time you probably find some capacity remains in the battery, so it will take mostly less than 8 hours. Charge it every night before you sleep, and it should be fully charged when you get up. With full charge, it can run about 20KM which is about 12.5miles. (testing on flat surface running non-stop).

Mine runs a minimum of 30 minutes on a full charge. I've never run it out so I'm not sure how long it might last.

Hi there....I can't say exactly how long the batteries last, but I do know that we went to Haiti and ran two of them ALL night while we slept for one week, and never changed the batteries. Hope that helps.

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.

Li-ion, after full charging run time is approx. 3.5 hours on full bright and 7 hours on low setting.

probably about 3 plus hours -we use it for travel so it is usually being plugged in every night or during use. Never have had a problem with too little battery.

I can't give you exact hours but I can tell you that my sons use their players at campouts for many hours and I have never seen them go off. I have never used mine for an extended time on battery.

I never let my battery die completely, but I would say it lasts on my laptop about 4 hours.

I power them down when I sleep by opening the small door. Then the batteries last about three weeks. There is a warning tone about an hour before the batteries fail. After about 6 months the Game Ears are performing flawlessly
