How many hours/days before the batteries are exhausted i.e, are these for a short outage or could they last a couple of days?

I haven't tested it (Thankfully) but I think I read in the packaging that it would last up to 48 hours. They are really fine LED lights so I could imagine it would last several hours for sure.

They turn on for 30 minutes, then off to conserve the battery. Then the remote allows you to manual turn on for unknown amount of time.

I am not sure if they will last days. I had an outage the other day and it lasted about 3 hours during that time the lights were on but started to flash so, I am not sure if they were about to go out or not. My lights came back on before mr beam went out. I hope this helps.

They will last through the night but only one (or maybe two) nights. The battery would quickly be extinguished and you would probably spend a lot on replacing the battery every other night. I also use a nightlight but I use a small light that plugs into the wall with a nightlight bulb in it. I also have one of these http://www.amazon.com/GE-Flower-Design-Incandescent-51386/dp/B002DNG9A2/ref=sr_1_18?ie=UTF8&qid=1410570644&sr=8-18&keywords=night+light which works really well. Hope that helps! These Mushroom lights are still fun and are really good for a few hours a night!

I bought them too. The batteries are probably dead. A similar thing happened to me. Mine lasted a couple of weeks with occasional use. Because they are "wireless", the system is always active even though the lights aren't on, looking for a signal to come on. Had I known of the short battery life BEFORE I purchased them, I wouldn't have bought them. Good luck to you.

five to six hours is the best I've gotten from them. If your getting 4.5 hours of use out of them you're doing ok. I've had 2 sets and they both got about 5 to 6 hours of use before I had to plug them in. Bob

Leon, I've had mine go for 3 full days with intermittent use maybe 3 to 4 hours a day, before I've become afraid they are going to be dead and charged them.

These are not designed for continuous lighting, but for intermittent and for a couple hours at a time. If left on continuously, the batteries will last around 25 to 30 hours. These had been considered for a commercial display case but were turned down due to having to change the batteries every 3 days.

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.

I would think so, but I wouldn't know since I havent used them yet. I got them as a back up. since eventually battery packs go out I figured I would only use them if an emergency occurred. Put them with bug out stuff (Hahahah i a prepper), figured If I get 6 months to a year of light with sun power in a OMG situation, the 12 bucks was worth it :) I should crack one open to see serial number or pack to see if they are available for back ups......hahaha back ups for my back ups couldnt hurt!

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

I would do one of two things. Charge them for 24 hours. Or send them back. Mine only lasted about 3 charges. That still put them roughly the price of a good disposable battery, but these are not high quality.

I am presently out of town and unable to look at the ones I have. I have never had a problem. They are always well charged and quite btrght when darkness falls. I will be home the end of the first week in Feb and would be happy to check and see if the batteries are replaceable. Off hand I think they may not be, I recall they are well sealed.

I personally do not knwo as I used them for a teaching aid in a project but depending on what batteries you use they can last anywhere from 24-48 hours continuous (LEDs on). The consumption on it in standby mode is very little (~70 micro Ah) so depending on if it is placed in a high volume traffic area or not will also determine how fast the batteries deplete. The consumption when it is on and lite is ~70 mAh.

Mine are still on the original batteries and I've used them through 3 dinner parties. They have run approximately 12 hours for me and there is still light. They are led lights so they pull very little off the batteries.

No idea... But when they worked, I loved them.... Then they didn't, after about 15 hours of use.

I had fantastic luck with regular double A batteries as well. Generally, they would last for maybe about 8 hours of life, and I always got accurate battery life readouts, and was always able to replace them when they got low without any issues.

I have not had to use them as of yet. If you are using them as lights in a dark area or tent - you should probably have spare batteries around.

I've had a couple of these and even when new I don't get more than an hour out of a charge. Currently it's about 30-45 minutes. I've never found the batteries to replace the original and my belief is they aren't replaceable. I just buy another WLB26B since they are relatively cheap and I like them because of the light output.
