How long does a battery last before it needs to be changed?

Batteries only last about three weeks of continuous operation. I was not able to open the unit without breaking it. The top and bottom are connected by tabs that release by twisting the base 1/8 of a turn and prying apart, unless the plastic has melted - like mine.

My best guess is 4 to 6 weeks. A lot depends on frequency and brightness which for me is important.

So far, its been about 3 months. If you cut it on at night and off early mornings when going to work will prolong the battery strength.

I do not recall the last time I changed batteries since purchase, consequently the battery life appears to be a good and a non issue. Obviously battery life is directly proportional to devise use time.

I couldn't say exactly, but definitely a long time! I don't change my battery often. I have 3 batteries: 2 Wasabi and 1 Lumix, and I haven't noticed a difference between them. They're always full-power according to the camera indicator when I switch to a new one. I'd say on average I change my battery every couple weeks, but the one I randomly replace it with may have been sitting a month at least.

Should take somewhere around a little under 80 minutes on a battery that hasn't been abused too much.

You cannot replace this battery, at least without some electronics trickery. I have purchased three of these headphones and used the first two heavily for three years. They finally started falling apart and the battery life started getting bad, but I would estimate I wore each unit 3,000-4,000 hours before they wore out. I highly recommend them. Some might feel discomfort at first (due to pressure) but they conform to the shape of your head after a while.

Agree with Frank ... some lithium ion batteries have a life span of as little as 3 years. Yours is likely closer to 10 years old. Before you replace the battery, though, plug the camera in to power and see if it will turn on. If not, it may just be time for a new camera.

I do not know exactly, but I am going to say at least two years. They rarely need changed. Battery life is impressive.

I have not had to replace the battery yet. I use it about 30-40 minutes 3-4 times per week. I have had it for about 7-8 to months. I have no complaint on that issue.

Normal 6 months to one year, if it is original batteries from box, it may not fresh as we need store it inside warehouse for a while, you may change it soon

I have not had to change the battery yet. If you have a Batteries Plus in your area, I would suggest you take it there just to get their advice. That is what I will do.

It depends on the charge status of the battery. Sometimes 5 minutes will do it.

I change batteries after about 2 hours to avoid battery failure. I learned the hard way.

I don't know. I have not had to replace battery as of yet. You might call the company. They were very helpful to me.

I'm not entirely sure on that. But I've been using mine for a 3-4 months and haven't replace the batteries once. I use it on the go, so I turn mine off between uses, but I have forgotten to turn it off from time to time meaning it's on for 24 hours or so. Still have not needed new batteries though. Hope this information is useful.

Battery life is pretty good (I think). I don't actually keep a record of battery changes, but my impression is that I must change batteries about every 6 months. I carry an extra in my golf bag because unlike someone else said, there seems to be little warning that it is about to quit.
