what is the overall life of the battery, if the battery fails over time can I replace it?

I use mine for both calls and streaming Pandora while I work. On a full charge using it heavily for five hours for music and then phone calls the rest of the day (7-8 hours); I rarely run out of juice. I don't know about replacing the battery. hope this helps. also to extend the battery life it helps to disconnect the headset from your phone or tablet when not using it.

I don't know about replacing the battery. It doesn't appear that you can remove it, but I'm not sure. As far as the battery life, my wife says she gets about 3-4 hours of continuous use watching a movie or YouTube videos. She has never only used it for calls alone. I hope this helps you.

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.

It is replaceable. If you use it less than 5 minutes per use a lithium battery should last a year or so.

Like the others said I guess it's in the item specs. To be honest I've never had to replace them or anything. I have two of these and one has been going for a few years. Admittedly they only get used on occasion but the batteries have held up.

The battery is removable, so as long as you can find a similar version of it, you can replace it.

Check with Optima. They tell you to take the battery back to where you bought it. Amazon will not take this back if it fails after a year. So that makes the 3 year warranty pretty much useless. But don't take my word for it. Check with Optima. You've been warned.

I am not sure, since I have not had to replace the battery. I will tellyou this I have had it for over a year. However, it does not get used all the time.

I can't say for sure. There are four small screws on the back. It's possible that you can get at the battery by removing them, but the instructions don't say anything about replacing the battery, so you would be on your own. Since the warranty is only 90 days, if the battery dies beyond that time, you have nothing to lose by trying.

You would have to contact the seller for Warranty info. However...These batteries aren't guaranteed for 'long'. Our history has been they last about 3 years. I feel we get our monies worth.

I don't expect to ever have to worry about the battery. These type of batteries last through thousands of charge cycles so if it fails in 10 years I will just buy a new one.

how long does a battery last? If I have not used it for more than a year will the battery still be good or do I need to replace it?

There are some guides online to tell you how to replace the battery. It involved de-soldering and soldering, so really only do-able for advanced DIYers. I tried and failed (but learned a lot about soldering on the way, so the $15 I invested was not completely wasted). Of course doing so will also void any warranty, so it's really only something that you will want to attempt if you have nothing to lose.

Sorry I can't provide an answer, but I'm in the same boat as you. Have you inquired about it via their customer support? I've been trying to locate the warranty information they sent with the battery so I can see what kind of stuff falls under it.

It varies, but usually, they tell you to replace any battery after one year or if you notice your items are not working as great - then it is time to change.

I have one that I've been using for almost three years and it's still going strong. Just change the batteries when it starts getting sluggish or acting weird and it'll come back to life.

Typically, battery can last up to 3 years, if kept on regular charge cycles. We recommend changing battery every two years.

Sorry, I've never tried to replace the battery, so I wouldn't know? I really don't use mine anymore and I'm looking to get rid of it. It's just collecting dust in my garage.

There are some batteries that can be replaced. There is apparently another internal battery that can only be replaced by sending back to factory. It is claimed to have a long life.
