Overall Battery Life (years)

Does anyone have any idea how long (how many recharges) the battery will take before it goes TU?  Is the battery replaceable?  Will SanDisk replace the battery and if so how much?

Is this one of those units that is a throwaway when the battery is no longer any good? 

It will take several years for a lithium ion battery to be dead completely, but there will be a substantial loss of capacity in about three years. For example, at three years my iPod’s battery was down to 2 hours on a full charge, from 12 hours originally. At four years, its still an hour or so, but it isn’t completely dead.

The Sansa press release says the battery isn’t replaceable, so technically its a throwaway. Third-party kits may become available at some point, but since its a new device those won’t show up for a couple of years.

Are there 3rd party kits available now for other non-replaceable MP3 player batts?

wow i didn’t know that…

its gonna suck in 4 years to buy another mp3 player after i just bought a 133 8 gb player…

The Fuze battery should last longer than 4 years, right?

This brings up another question. Is there a right way and a wrong way to re-charge the Fuze batt?

I have yet to fully discharge it because I keep plugging it back up to load more media before the batt life is half way used.

Li-Ion batteries don’t usually die suddently, they typically experience a protracted death that starts around the third year. Forunately the Fuze has some pretty substantial battery life, so a 50% or even 75% reduction in battery life still gives you several hours per charge. There are third-party companies that sell replacement batteries for several other brands of players, but I haven’t seen any for Sandisk (yet). Keep in mind, Sandisk sold e-series replacement batteries, so there probably wasn’t much demand for third-party batteries.

Some (plagerized) general tips for improving LiIon battery life:

  • Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life is mainly cause by heat rather than charge / discharge patterns.
  • Batteries with fuel gauge should be calibrated by applying a deliberate full discharge once every 30 charges. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely. (I’m not sure if this applies with the Fuze)
  • Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.

speaking of battery life just today i had a charged battery and about 4 hours of continous the battery was low(red) and then it shut off. i think it had to do with me keeping it in my hand for about 3 hours,it was very hot.

I forgot to mention: LiIon batteries are also typically rated at about 1,000 full drains. So if you drain it from 100% to 75%, for example, that is 1/4 of a full drain. If you use an mp3 player on battery a lot (i.e. several hours a day every day), that could come into play.

This somewhat sucks :(…I mean why can’t they use a separate battery (like the minidisc player)? It is a terrible thought to know that this fresh out of the bos fuze i have just bought will have to be thrown away in 3-4 years. I honestly just want one good player where i dont ever have to worry about going through whats good or not when wanting a new one. One good player i can settle with lol. I wonder if it can be replaced with the right engineering…I suppose this is one piece of news i looked over before buying my Fuze…if i had known this, i probably would’ve waited to see what else Sansa will bring out. For some reason this news is very discomforting to me. It seems to me that it could be either a direct or indirect marketing ploy. I mean i just spent money on this Fuze thinking this was “it”. Now i know that within 2-3 years im DEFINITELY going to have to get a new player, after i’ve bought a skin for this thing and everything. I’ve had to allow 2 minidisc players sit in dust because of odd problems and now, as good as my Fuze will look years from now, it too, with its skin and all will have to be tossed away… Sansa i hope youre reading this, and in the future it would probably be more beneficial for us consumers to have a battery that can be replaced, allowing us to keep such a wonderful player known as the Fuze. I see no reason why this should not or cannot be done. 

*P.S - what is a “3rd Party Kit”?

This is not an issue unique to Sansa. Most recent MP3 players don’t have replaceable batteries. The reason is simple - not having to worry about making the device easy to open and/or the battery easy to replace allows the designers to make a smaller, thinner player. Players with non-replaceable batteries have always outsold players with replaceable batteries because size is a bigger issue to buyers.

A “third party kit” is a product sold by someone other than the original manufacturer. They’ll typically include a battery, instructions, and perhaps a tool to pry the device open. Typically they cost about $20. The Fuze is selling well enough that I expect these will start showing up in a couple of years.

Why do you think you’d need a new one in 2-3 years? The battery life should still be pretty good in that timeframe. I’d expect to get 8-10 hours of play time for four or so years. And technolgy changes so much that a 4-yo player isn’t very desirable - for example, I could have replaced the battery in my old iPod, but its black&white screen is hard to read, even a new brand battery only lasts 12 hours, its only 20GB but several times as big as a Fuze, and its a hard drive so I have to pamper it.

Well bdb, you do have a point but i think ultimately it all boils down to personal preference. I’d love to keep my player for 4+ years. If i love it now, trust me, i’ll love it then lol. Here is hoping for one of these kits someday because the Fuze is honestly an incredible player.

I don’t have a problem with this because I purchased Best Buy’s 2-year replacement warranty. By the time 2 years comes around the player will probably be aching to be replaced–not because it’s dying, but simply because better tech for the same price will have come out.

Plus, by then I will probably have expanded my musical horizons enough to need a much bigger player. 

The future Fuze name may refer to Cereberal Communicator (CC) support too.

For those of you with the facial wrinkles to prove it, remember Our Man Flint (James Coburn)?  Look up " The President’s Analyst".

If not, pick up the DVD. 

Sansafix , will CC support be in the future?  So far, the Fuze supports “total sound”.

Your Fuze will last for several years on that wee LiPo cell, and will have lots of scrapes and bruises by then.  Knowing SanDisk, there will be a 32GB one on the store shelves by the time that cell wears out.

Never underestimate the value of recycled technology.

My 8GB Fuze is currently in a silicone case with a screen protector, and loaded with an 8GB Sandisk microSD card, so it’s not going to be damaged, and the storage capacity is rockin’ for now.  I’m sure in a couple of years, I’ll want a newer, shinier version, but I look forward to passing it off to a friend or relative to enjoy as well, as I did with my e250 and c240.  The c240 went to a friend to listen to audiobooks through Rockbox, the e250 to another friend to use under Rockbox as well.

Investing in a replacement batter for the Fuze before handing it off can guarantee several more years of active life for a user that probably would do without a PMP for the forseeable future… well worth ~$20, in my belief.

    Actually, the Fuze has a Lithium-Polymer battery, not a Lithium Ion battery.  See http://forums.sandisk.com/sansa/board/message?board.id=sansafuse&thread.id=1 for general information on the Fuze.  According to information I’ve read online about Li-Polymer batteries they are supposed to last nearly twice as long (in years) as Li-Ion batteries.  They also last longer in between charges.  (Compare, for example, how the Fuze is rated at 24 hours vs. 20 hours for e200.)

If you can reasonably expect a Li-Ion battery to give you 3 good years of service, then I’d think you can also reasonably expect the Li-Polymer to give you from 5 to 6 years of service.  Technology does change very quickly in the electronics industry, so in 5 or 6 years you’ll probably want to upgrade your player anyway.  You can expect advances in flash drive technology in the next 5 to 6 years.  Where the current Fuze and e200 flash drive players have 2 to 8 GB of flash memory, the capacities in 5 to 6 years will likely be much higher.  Samsung recently announced a 256 GB flash drive. 

Hi,

When I connected my sansa e200 to the “Altec Lansing inMotion Portable Stereo System”,I was just trying it out(let me clarify) but after I disconnected only the lights of the mp3 were on and the screen was black, it was like if the mp3 was freezed. Then I hold the Power button to turn it off so that the device powered down, after that, I turn it on but nothing happen. And the back of the mp3 start heating up. My question is: Was it because of the battery? Was it because of the stereo system? or some of the things inside the mp3 was burnt…?.

Is that “Altec Lansing inMotion Portable Stereo System” specifically designed for use with the Sansa?  Never plug a Sansa’s 30-pin connector into anything designed for iPod because it can (and usually does) cause serious damage to the Sansa.

Yes, it was designed for the Sansa…

It’s important to have the latest version of the firmware for your Sansa to operate correctly with a dock.

SanDisk has addressed docking compatibility issues in the latest releases, whether your device is an e200 or Fuze.

Be sure to check your firmware version.
