The extended life battery generally lasts about 2.5 hours of continuous use.

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.

The batteries with intermittent use, lasted about 4 1/2 to five months. It may have been a bit longer, but no more then 6 months. I don't have any complaints. The screen shows enough detail with a night light outside.

I had one set of batteries last about 3 months.. the second one was still going at around 5 months when I took it off the wall.

I've got this same set on my bike and I use rechargeable batteries in mine. They usually last about a month to a month 1/2 before having to be recharged. I've been using the same batteries since I got this set of lights about 4 years ago.

I put new batteries in last year after I first installed the lights. I am still using the same batteries. Usually I leave mine on for about 2 hours at a time. I've probably used mine 6-7 times so far with the same batteries.

I've tried cheap batteries and expensive batteries and there is a difference in this type of device. Niteize sells replacement batteries that seem to last about 6-8 weeks with a daily 15-30 minute walk (usage). With the cheap batteries I was experiencing two weeks and they would go dead. Bottom line, you get what you pay for. As another response stated,you simply pry the back plastic off to gain access to the batteries - each device requires two batteries.

I just change the batteries and don't bother with the other stuff. batteries last anywhere from 2 weeks to 3+ weeks depending on how much I use it.

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.

On the higher setting, they probably lasted around 18-24 hours. On the lower setting, you could probably expect 24-36. We used them in Haiti and were pretty pleased with their performance. Ended up using half of the batteries that I expected to.

The first set of Duracell batteries in one light on our front porch (activated a few times a night on average) lasted for four years. I had to replace them earlier this year so i don't know how long these second set will last.

Approximately 8 and sometimes 10 hours if I leave them on and if I buy really good batteries. They are easy to turn off and on to save battery life and easy to change the batteries

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.

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

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

Not long, had to buy an extra 3 pack of batteries to keep on hand. Never leave home without an extra one.

I don't know how long the batteries are supposed to last, but this seems unusual for them to die weekly. I ran mine last year for approximately 4 hours per week and unit battery still worked this year.

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.
