how long do the batteries last

Depends on the brightness set when on battery and how many applications are running. The brighter and more processes there are, the quicker the battery drains. If it's just for light use and not blasted on full brightness it should last about 3-4 hrs, at least that's on my laptop.

The HP 4530s battery has been very dependable. I've had the laptop for roughly 2 years and I still get a least 3 hrs. of use on the battery. Obviously how you have it set up - "Power Saver" mode versus "Optimized", screen brightness, when to turn off display and when it goes into sleep all make an impact (as well as what programs/software you're using). It has always met my needs better then other laptops I have previously owned. I hope this answers your question. You should not be disappointed.

Richard I can't say how long the batteries last because I have not changed my yet after having the light for more than a year. I don't use the light much--mainly to take care of coons that our dog trees at night. Probably a dozen and a half coons and it doesn't usually require the light being on for more than ten or so minutes for each coon. Hope this helps.

I don't leave them on all the time but at least 20 to 30 hrs prob more. They are a common size flat battery easy to replace and has like 3 settings of flashing and one solid. My batteries havent ran out yet.

My battery last for a while. About 2-3 months, but I think it depends on how much it has to be used. The batteries are cheap at Walmart.

They last about a year. You can buy upgrades for it ( more run time). Batteries aren't covered. They are expected to be replaced.

If I recall correctly they take AA batteries. The battery life would depend on the batteries, I guess. We don't use them for very long at a time so I am sorry I cannot be of much help.

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.

I use the Duracell AA batteries and I believe it takes 16 total. They last quite a while depending on usage.

We have been using ours since at least June of last year & the battery has not died yet. So they last a long time.

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.

About a half hour. Then the charge lasts about 10 minutes. Purchase multiple batteries!

Batteries will last 20 to 40 hours depending on factors such as quality of batteries and if headphones are being used to save power.

I have four of these, all installed since 9/2013. One of the batteries died after about 6 months, which kinda worried me, but the other three are still on the original batteries and still sound loudly when tested. So, 6 months to at least 17 months. These are nice little units, worth a few extra bucks for the small form factor.

several hours, really, I can't say. I have one and my son-in-law has one, both about 1 1/2 years old. Only charged twice each and not because it was low, just thought it needed it after a night of use calling coyotes.

Usually the battery last between 4 to 6 hours. Just make sure you don't drain the battery. When you see that the battery is almost gone, charge it to prolong the battery life.

On a set of batteries? Probably, I would say 8 hours. It's not very loud. It's good for home use.
