Battery lasts a long time, very bright, and great price. I work in security and I need a dependable light, this fills the bill

Not long. Seems like mine was dead after 4-5 hours of use over several months. Never replaced the battery so I've been stuck with a white, plastic bulb for years now. Wouldn't purchase again.

It lasts a good while. I have a large yard and only need to switch to the other battery for the last quarter of the yard. I have never run down both batteries if they were fully charged when I began.

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

the battery works quite well. it lasts at least one to two days if you consistently use it. although its off for a while, you still can turn it on without losing power not being used.

In my experience, a fully charged battery lasts 7 to 8 hours, depending on how loud you have it and how far from the base station it is.

Not long at all. Maybe 30 min from a completely dead battery. Lasts a good while too.

On average it will last between 4-6 hours depending on what it is you're doing. I tend to leave it charging overnight so that it's fully charged in the morning. When I start doing my college course work and browsing the internet the battery will last me a good solid 3-4 hours while in constant use.

I'm not sure about the battery life. But I haven't changed battery yet since I bought mine. Just be sure to turn it off after you use it.

That completely depends on the speed you are running it. If you only run it at full speed, it may last two hours on a charged battery. If you run at the lowest speed, it can last up to 15 hours or so.

I have run it for about 6 hrs before on a fully charged battery. Sometimes 7 depending on how often it is used. I keep a spare fully chargedbattery on hand just in case.

Battery is supposed to last about 8 hours but can vary depending on volume, etc. I haven't really pushed it that far to see if it will last that long.

It was lasting up to 20-25 minutes for me. I always keep it plugged in. Use it almost every day, several times a day. But now that I've had it for about 9 months, the battery is no longer lasting very long. I think maybe 5 minutes, tops, before it starts to lose power. I am here to check out the return policy, because I think I got a lemon. My last Dustbuster lasted several years with regular use. It's way too early for this one to be dying already.

I love this thing. Had it for a while and haven't replaced the battery. You should be fine for months

Greetings. Theoretically speaking, the batteries can last 100-120 hours. But it will also be affected by the battery type and usage. Thanks for your question.

Its a pretty long time. I charge it occasionally, but it has never died on me while I was using it.

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