Only about 8 minutes because my kids run them full throttle at all times. I recommend buying a second or even a larger batter 3500 Mih etc. will give you more time.

I have ran the car thirty minutes before I see a slow down due to lack of power.

I can't tell you how many hours but I've had mine since May of last year and have only changed the batteries once. I have them on every night from about 7 to 12.

Pretty long. Months I would say. We got ours about 10 months ago and I think I have only replaced the batteries 2 or 3 times. Pretty good considering it is used almost every night.

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

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

depends on your weight. 3 or 4 hours for me when batteries were new, but unit is cheaply made and doesn't last long.

I have had mine for 3 months and have used it once or twice a day since then. I just changed the batteries in it today. So depending on you use I would say 2 to 3 months.

Not sure. I used it for a week, a few hours almost every night. I have yet to change the batteries since I got it.

We have had six of these units in our home for over a year. We replaced all batteries after approximately one year. One unit is outside in the cold and heat and it's batteries lasted a year. The unit will give a little chime note every three or four minutes when the batteries need to be replaced.

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.

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 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.

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

I do not have an exact time that the batteries last. I can tell you that I've used it numerous times and haven't really had any issues with battery life.

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.

Tough to answer. Length of time in use and volume will impact batteries. I often use it 4 hours a day and they last about two weeks.

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.
