10 years? No way. Realistically one should probably expect 3 years of reasonable use. Over time the battery capacity will decrease. While the battery might not be totally dead in 3 years, if its capacity is less than half the original capacity, many might want a new player.


Way. I can believe this is plausible. Certianly not every unit as some are subjected to extremes in temperature and use, but when averaged out it shouldn't be that hard to imagine or expect. I have a Samsung cellular phone that is coming up on 9 years old, still with the same original Li-ion battery. It's used every day (with a few holidays off). Granted I'm not talking on it 24/7, but it is still ON drawing current. Also, I'll admit that I have to charge it more often now as the battery is getting noticably weaker, but the fact is it is really old and still works.

 

The Li-po battery is the next generation technology over the Li-ion, so I could see this lasting 10 years with care. Maybe not for someone who has their earbuds in 12 hours a day, but with moderate use and sensible care, why couldn't it last a decade or more?

 

I don't have the link handy to the post, but it was Sansafix recently who offered that he'd recycle someone's Fuze for them when the battery finally died, because they couldn't stand the thought of throwing it away and that these batteries were not the environmentally-correct and forward-thinking thing to use. He said to look him up in about 10 years. Smiley Wink

Re: Battery replacement?

Well I certainly seem to have sparked a lively debate, and many thanks for all your input. I'm very interested in the Lithium-Polymer technology and will be watching that as it develops and hopefully proves itself to be the answer we have all been searching for. But promises have been made before, and to date, most rechargeable batteries fail for one reason or another long before the device itself. I still don't accept the argument that it is too difficult and expensive to integrate user replaceable batteries: Mobile phone manufacturers manage it very well indeed. I'd be very happy with a player the size of my ancient Motorola RAZR, several years old and now on its third battery. By contrast, I have an mp3 player less than two years old that no longer holds a useful charge and is therefore beyond economic repair. Many people seem to find that acceptable but I do not. You can call me a dinosaur or whatever you want, but if something still works, I don't want to throw it away in favour of the next shiny new thing. It would also be very useful to be able to carry a spare charged battery. I still think this is a deliberate policy by manufacturers to create premature obsolescence, but I think they are missing a trick: I think lots of people have been caught out by non-replaceable batteries and are getting fed up with it. No doubt the debate will continue, but I shall continue my search for a more sustainable device.

Re: Battery replacement?

New to Forum so this may have been answered before but I've read this thread through and this brings up my question since buying my Sansa Fuze about three months ago.  With this type of battery how low should you let the power go before charging?  I know with some types of batteries it is better for the life of the battery to wait until it is pretty low before charging.  Is that the case here?  Thanks for your help and I have to tell you I am really happy with my Sansa Fuze I use it for audio books and have transfer 4 so far without any issues with the transfer or listening.  I love it.

Patty -

 

Your Fuze's battery prefers frequent top-offs with an occasional 'tall drink of water'. Don't run it down to the red zone every time. If you're like most new user's, you will be plugging it into your computer quite often to add new music to it, so it will take 'small sips' of power at the same time. Smiley Happy

Re: Battery replacement?

Tnanks Tapeworm and you do know your new users don't you?!  That is exactly what is happening.  I am using my Fuze for audiobooks like I mentioned so everytime I transfer the book to my Fuze I am plugging it in.  I cringed everytime thinking am I doing something to harm it by plugging it in and unplugging for what I felt were short periods of time and now I'm finding out from you it is a good thing topping off the battery with some well needed power.  Thanks for the info and it will probably never get down to the red because of this.  Smiley Happy  Right back at you.  Take care, Patty

Oh...

 

And here I was thinking that it's better to always let it empty itself completely before recharging it! Smiley Surprised Luckily I've only recently bought it so I've only recharged it one time so far, I'll be sure to recharge it before it gets to 0% power next time, thanks!!!

 

So these new kinds of batteries don't suffer the memory effect the older batteries had, that if you recharged them before they were completely empty they would more rapidly lose capacity?

I doubt that the Fuze electronic would let the battery go down to 0% power, because rechargeable batteries usually don't like to be totally discharged. And what they actually hate is to be lie about almost empty and be drained by doing nothing, instead they like to work on a regular basis. But of course I am not a professional electronic specialist. I only know that when my power hungry camcorder puts out the empty signal, the replaceable batteries are still about half full and can power up other equipment for quite a while. Someone told me that charging electronics today is intelligent and able to learn, so to fully charge battery powered equipment and then let it be discharged to the empty signal for one or two cycles in the beginning gives it a chance to do its job optimally. Does the Fuze provide different working conditions to its battery?

Re: Battery replacement?

What I have see with the latest firmware is that the battery meter seems to go down much faster then with earlier firmware.. I confirmed this by downgrading the firmware long enough to confirm this..  With the latest firmware if the battery meter is down to 1/4 or a little less (still green) and I look under setting I have 49% battery left..  This is not a big deal but for some users one may think that there battery is getting weak do to use or age, when it's really not!

*His* 8GB Silver Fuze v01.02.31A also 8GB MicroSDHC card installed *Hers* 4GB red Fuze with 16GB micro SDHC card! Firmware v01.02.31A still installed. Acquired another 8GB Fuze also with firmware v01.02.31A now..

No, those were NiCad rechargables that were most common 20+ years ago, and to a lesser extent, NiMH batteries like those in power tool packs (although even some power tools are now using Li-ion packs).  Battery memory effect is, for the most part, a thing of the somewhat distant past.  Certainly nothing you have to worry about with modern portable electronic device like a DAP or cell phone.  The best thing to do with modern devices is to just charge them when you're not using them, and don't worry about the battery.
