Not long. May be 2 hours. I don't move it around and it is not an issue for me.

They last very long, I bought this in July 2013, and I just recharged the D batteries at the beginning of December 2013. The batteries weren't even drained, I just wanted to make sure it wouldn't die before I went on vacation.

The battery lasted about as long as most. I bought a back up, so I never worried.

Wel we don't run the lights all the time so I only know that I have only changed the batteries once so far. We run them when we have guests over. It appears that they last pretty long though.

I had read somewhere online that people had the batteries last 30days. I found that after 48hrs the motion detection started to be significantly less sensitive until I put fresh ones in again.

Generally lasts about 20-30 minutes of continuous use with fresh alkaline batteries. If you switch it off when not in use, you can get as much as 40 minutes out of it total.

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.

Depends on how you [ab]use them. If you often run them all the way down, and/or run them down only 1 or 2% and back up to 100%, they may last less than a year (or only take half a charge after a while). If you seldom run them below 30%, and don't recharge until they're 90% or less, they may last 5 years or more.

I've had them for more than 1-1/2 years without replacing the batteries but they're not always on. We like it a lot.

I believe the first set of batteries lasted about two years, but it also depends on usage and how many people are using it and how often.

I've had this for months but I don't read every night. It's still going strong for me. Just realize the batteries are going to have to be replaced eventually. If I had to guess, I'd bet the batteries would run constantly for 48 hours and still be useable.

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.

Can't give exact time but they last pretty good time. They use reg AAA batterys.

they last pretty long for me. It really depends on the type of item your using these batteries for. But for me they always last at least 5 hours. Theyre pretty reliable for me. They also take like a day to fully recharge for me, i go to sleep & when i wake up their fully charged.

I use them alot , most of the day in fact, and I can get around 5 hours (talking on Skype and listening to Youtube videos) of use out of them before they need recharged. They take about a hour to recharge ( I just use them with the charging cord plugged in)

The rechargeable batteries in mine last about 8 hours on a full charge with the radio playing. When I use alkaline batteries I get about 20 hours of play time.
