I don't know the lifetime of the battery or if it can be replaced. Each charge hold about a week of daily use if set in one of the blinking modes. So far the battery is working fine.

I actually spoke to Cygolite about this when I was deciding between this and the Expillion series and the guy said that you could send it to them and they'd replace the battery. I don't remember how much it was, but frankly by the time this gives out there will be a better version out for the same money. Case in point: the Metro 360 which was released for 2014. Not saying don't have the battery replaced, but weigh the cost / benefits before you do.

No, it's not considered user replaceable. Though here is a video of someone taking it apart, and he shows how you would replace the battery if you're adventurous and careful, and if batteries are available: http://www.youtube.com/watch?v=aI1Lm_-1djY&mode=related&search=

I can't say over the long-term, but I have had mine for three months, I use it everyday for hours at a time, and I have not yet had to replace the battery.

Yes, replacement batteries are available, but not for the purpose of swapping out of to extend ride time. If the battery were to stop holding a charge it can be replaced.

It is not designed to replace the battery. It should last a few years before it dies though.

Yes it can be replaced by the consumer. The one side cover opens and the battery comes right out.

Could this battery be found and replaced with a little bit of technical expertise?

yes the battery can be replaced, and it is hard to open it up. I had to ask my husband how to do it.

You might be able to. Unscrew the sides and if the rechargeable battery isn't soldered in, it might be replaceable.

I don't know about the overall lifespan of the battery, but I do believe replacements are available or at least new pens are and I don't believe they cost much. It's like 15 dollars for a whole new pen. I've had mine for a year now, with daily usage reaching over 8 hours a day sometimes and I've gone as long as 2 months without ever charging it and still no sign of it slowing down.

No it cannot be replaced, since it's more than 2 years old and out of warranty they will not fix it citing un availability of parts. You will need to buy a new one. If you are good at taking things apart and soldering you can try to dismantle it and get an after market battery.

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.

I don't believe that the battery is replaceable. The package says that it is a rechargeable NiMH. You might be able to get at the batteries by removing the two small recessed screws near the bottom of the timer.

I do not believe you can replace the battery. I contacted the seller of mine about this and got conflicting info. They lastly told me to pry off the back to replace the battery which I believe will break the unit if attempted. My 2 still work so I have not tried it yet.

But, to your second question, the battery is not replaceable. There are sites on the internet where you can find out how to replace the battery though. My guess is that by the time the battery dies it will be time for a new model anyway. The battery should last at least 5 years I am being told.

I'm not sure if the battery can be replaced, most likely no. What I do know is that I played mines for about 8 hours at full volume before the battery died so I'd say that's decent. The type of battery it is you would probably get a couple hundred recharges. You may want to alternate between using it till the battery is completely drained and using it while charging. It will help to extend the battery life. Hope this helps.

It is a built in Lithium battery. So, I'm assuming no way to replace it. They are asking me to assume the charge of shipping and send a $9.95 check for possible repairs because mine stopped working. That would probably be what you would need to do if yours needed a new battery. Since I've had mine less than 6 months I'm not a happy camper. Probably will not send it back. (This is their idea of a guarantee, I guess.)
