Yes, they're $89 each, but they have them in stock as of 9/15 @ 3:15PM... I've had batteries on backorder in various places, and found this vendor today.

http://www.partstore.com

With the 6000's limited production run, seems like it's a good thing to keep an extra battery or two around for the long haul.

Best Regards,
Stac
speculatrix
site still advertises the batteries, same price, so I hope they still have stock.

thanks for the top tip.

Apparently the lifespan of a litium ion battery is measured from production date. (based on some stuff I read recently). If this is so, then a "new, sealed" batery of the same date as the one I'm using might not live that much longer than the one in my Z. Hardly worth $100 even if one could be found.

Does anyone have any useful and informed insight here?

My conclusion is (as you can see by me recent post in 6000 hardware) is that some kind of enclosure that uses off-the-shelf batteries and snaps into the 6000's battery well is the best solution. The problem design and constuction.

True. But, there are a bunch of factors that determine how fast it degrades.

If you want to keep an LI-ON battery for storage, you get the best life by doing the following:

1) Discharge to 40%
2) Seal (to prevent moisture) and refrigerate.

I've seen numbers that the battery will lose < 1% / year of capacity in these conditions.

thanks ! that is useful info

I contacted our supplier for the 6000's in Japan and they cannot get the EABL-09 I have no idea why and they didn't understand it either. However we can get the cf/battery extender that does include 1 EABL-09 It takes us 2 weeks to get it and they are quite expensive but it doubles your battery for the 6000. I know its not the best solution but it is a solution none the less.

Well vendors, keep us updated. I will happily buy two EA-BL09 from the first vendor (who ships to the US) who gets new batteries in stock. wink.gif

Hey all,

I just got off the phone with a friend of mine who is a Missionary in Japan. He's gonna poke around and see if he can find any locally in stores etc. that might be catching dust. If he has any success he'll get back up with me and let me know how many he can get and what the price would be. I told him that I'm sure if anyone else is interested in getting a spare or three we'd definitely make it worth his while. Plus the shipping would be much cheaper if he could ship them all at the same time.

So if you're interested go ahead and send me a PM and I'll toss you back a reply when I know more. I'm actually fairly spooked about this issue- not being able to purchase replacement batteries would be more than a minor problem in the future. If this drops through we will have no choice but to find a way to create a viable replacement ourselves, and I find that very disinheartening.

Be Safe,
-NeuroShock

I'm definitely in for it, if the price to England is less than US$75.

I am also working on this problem. I have a battery manufacturer looking into making these. Once the prototype is done and has been tested we will let you know.

I would definitely prefer newly created batteries over batteries that have been sitting on a shelf for a year. Considering I am getting rid of the expansion sleeve (loved the functionality, but hated the bulk), I might consider an extra battery.

This would be awesome. I hope you are able to find a solution to it. I've thought about purchasing the expansion sleeve for the 6k, but I am not keen on the additional bulk added to the unit.

Thanks.

you might take a look at doing something different..like making a snap-in battery pack that takes AA or AAA or some other commonly available battery. I was planning to look into this myself, but you are in a better position to do so, if inclined, I think.

a pack that takes 6 AAA might not stick out very far....and would provide plnty of cheap power. The design could easily be applied to make clamshell battery packs as well.

given a AAA is @ 850 mAh... that is a total fo 5100 mAh per pack... though I guess some useful power will be lost in the voltage regulation, etc.

Long life and off-the-shelf batteries would be a real help for travelers, I think.

I think this is a good idea, but in order to be truly practical, it would need to integrate with the 6000 charging circuit, or else one of two annoying things would happen: Either you would need to lug around an external battery charger, or a lot of spare batteries. The 6000 is bulky enough as it is...

If you need 3.7 volts then you will not get 5 Ah you will get 1500 maH or so with two lots of 3 in parallel. I don't think it would be too sucessful at all. Paralleling NiMH isn't a good idea anyway and the power weight ratio is crap comapred to Lithium polymer.

oops. er, yeah more than 1.5 volts is needed.

custom lithium polymer is beginning to show serious problems with lifespan and replaceability. Given that a Z will run for a while off a 9 -volt (with a regulator, etc) surely there is a decent off-the-shelf option? Especially given that the newer Z's don't boot without a battery? It isn't so much that it is a better choice for "new" performance, it is a better choice for the longevity of the device, given the expense, obscurity, and mortality of appropritate lithium polymer batteries. power for weight means precisely nothing when comparing easily available (if heavy)power to a dead and irreplaceable (though light) custom battery.

If marc can deliver lithium polymers at a good price and a steady supply, that would be nice, but I'm afraid that we are going to be faced with a limited run and the same problem down the road.

I have had a standing order on Amazon for a 6000L battery, just inc ase they had any come in.

I received a notice a few minutes ago that the order has been filled! According to Amazon, they have two in stock at about $75.

Amazon Link to 6000L batteries

There are also two used ones listed for $59.

Good luck!

I still think that using those cheap Nokia LI-ION BL5C batteries is the best way to go. . .

no, he's referring to the idea of taking Nokia-compatible batteries and converting them to 6000 ones, like some guy here is doing for 7xx/8xx/1000/3xxx.
