Battery Technology
<div class="IPBDescription">aren't you disappointed?</div> I for one am. Spending 7 bucks on 2 batteries just to have them run out in 3 hours (give or take) on a cd player. Everything in technology is progressing at an amazing speed, except for these crappy batteries that don't have enough charge to even run a cellphone.
Thats all I really have to say, its a pretty useless post, but if anyone else feels the same/different way, care to share?

Because I for one have found the wonderful technology that is....
The Rechargeable Battery!
That was a few years ago.... PLASMA REACTORS! >_<
But, the thing is, technology has been getting better. I have a new CD walkman and a VERY old one. The new one takes 2 batteries and they last for hours and hours and hours and hours. The old one takes 4 batteries and lasts around about 23 minutes. The point is, technology has got far more efficient with power usage, if you find your batteries are getting used really quickly, maybe it's your CD player, not the batteries.
Hell, i've got a Minidisc player that uses 1 battery and lasts for months at a time, even on cheap batteries.
Either the CD Player sucks, or the Batteries do. I bought an eight pack of batteries for $5 and my CD Player takes hours to run go down a little bit. Tough Luck.
Batteries may not be advancing, but everything else is.

Indeed. I've noticed that I last longer on a single charge than before.

i do agree that battery technology hasnt improved much, I want my disposable nuclear reactor <!--emo&:(--><img src='http://www.unknownworlds.com/forums/html/emoticons/sad.gif' border='0' style='vertical-align:middle' alt='sad.gif'><!--endemo-->
the ba-5590 ,battery(or li-so2 battery), wich uses the so2 chemistry has ben the main battery type used by the us military in communication applications over the past 10 - 15 years.
it is the only lithium technology currently available that has a proven successful record in combat situations and is the most cost effective solution available for the us military. but this battery is not powerfull enough for the landwarrior system. the battery company saft will produce some military type high capacity batterys for commercial use.the first battery that saft will produce with this new technology will be a ba-5590 based battery which is the highest volume battery purchased by the us military.
Or...you know. You <i>could</i> just claim yourself a sun. <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif'><!--endemo-->
And as multiple people have said - it's more a question of how <i>well</i> one's electronic appliance uses the battery than a question of the power of the battery itself. Battteries alone are a pretty easy concept. Unfortunately, finding an affordable alternative chemical reaction that lasts a long time and an be as easily be controlled is a daunting task.
Of course, the new lithium ion batteries have proved to fit that bill pretty well. I think we'll be seeing a lot more about them in the near future.
I've heard rumors that some countries in Europe are trying to control this by forcing ink cartridge makers to recycle the majority of the materials or face fines/taxes. If we could tax Duracell and Energizer for each non-earth-friendly battery they make, I'm sure they'd change their tune pretty quick. It'd be better for us all, really -- no need to waste as much time finding, buying, and replacing dead batteries as often, with an environmental bonus to boot.

I concur in all those points. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->
Unless you HAVE to have super-high stamina on a device, go with those cheap-o batteries. At a wholesale club I get a brick of 48 toshiba AAs for 10 bucks.
Just wait till ion batteries come out.. the ones that use electrons instead of molecules to store stuff. Read about them in Popular Science- they hold more, charge faster, and last almost forever.

Note the ENORMOUS battery pack fitted to the dudes belt.
Of course, as has been said, thanks to consumerism and capitalism, disposables are "in" because they're a neigh limitless source of revenue for the company, and the mindless "bargin" hunter populous doesn't care enough to seach out alternate sources...
And since I don't think it's been said enough, $7 for two? Tell me its not USD, cause then I can understand, but 4 Energizer batts are only $7 USD... Sam's club has like 80 packs for $10...
Lithium batteries are disposable, but last longer in high drain devices. However, for the price, I would ignore these for CD players. They do last a long time, run well in cold weather, and rarely leak, but are very expensive ($10-$12 USD for a 4 pack). They don't recharge, either (at least not in AA form).
Rechargeable batteries are a much better decision for high drain devices. Here are the types available in AA form:
<b>Nickel Cadmium</b>: DO NOT PURCHASE THESE. They contain 'memory' which means that one must drain the batteries entirely before recharging. If this is not done each time, the battery charge will diminish.
<b>Nickel Metal Hydride</b>: These are by far the most long lasting recharageable batteries available for AA or AAA. Batteries usually cost $10-$12 (USD) for 4 AA or AAA. Chargers can be anywhere from $10-$20 (USD).
<b>Alkaline</b>: Rayovac recently released recharageable alkaline batteries. These do not have memory. These must be charged in chargers that accept recharable alkaline batteries. This means that a new charger must be purchased for all those with NiMH batteries. A NiMH/Alkaline charger can be found for $20 (USD) from Rayovac. Rechargeable alkaline do not last as long as disposable alkaline, but only take around 1 hour to recharge.
It has been said that rechargeable batteries don't last long on a shelf (one forum user said three months without charging would reduce the life of the battery). However, in my experience, I have been satisfied with the life of rechargable alkaline (for short trips, since they don't last very long in high drain devices) and NiMH (for longer trips).
i got a battery in my mp3 player that has a 12 hour charge... if you use it more and wear it in it could go up to a 15 hour charge.... proud of it
