Another thought had crossed my mind actually. Something in Sony's battery (protective circuit) that makes it propriety which prevents a different battery from communicating. 

Or in this case accept a charge. The new battery will be here in a few days.

New battery arrived - same thing, won't charge.

Ok, I now have this sorted.

I've taken one up on Sony working right around their system making the Walkman run on external / interchangeable batteries and Its quite an easy painless process. What you need is a 14500 3.7v battery, the kind used in some high powered torches. Be aware these batteries are not your regular 1.2v or 1.5v AA battery used in common devices but instead 3.7volt. They're however the same size as an AA battery.

1) Here's an example of the battery used: http://www.ebay.com.au/itm/Free-Shipping-2x-1200mAh-14500-3-7v-Li-ion-Rechargeable-Protected-Battery-New-/201143743937?pt=AU_Electronics_Batteries_Chargers&hash=item2ed519f5c1


2) Another thing you'll need is a battery casing to put it all together.

Here's an example: http://www.ebay.com.au/itm/271633240002?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

(keep in mind you only need one battery, the above casing supports two though I set it up for a one battery assembly) 


3) Last thing you'll need is the original battery harness which was attached to the stock Sony battery, this is very important as the Walkmans mother board connection depends on this proprietary plug, without one you'll be pushing to get this job done.



When you have everything, open the Walkman then carefully drill a hole in the back of the Walkman casing about 1cm from where the connection is on the mother board. Poke the wires through and solder the original battery harness to the positive and negative wires, be sure to tape them off or use heat shrink you don't want any shorts inside the Walkman.



There will be a white wire as well on the original harness, disregard it, chop it off clean or tape it off. You don't need this as I'm aware it's just for monitoring charge and temperature purposes. All you want is the red / black wires.





Attach the battery compartment to the back of the Walkman, I used double sided tape for now but will secure it with something else later (probably dual lock velcro). Make sure you don't plug anything in until you have everything soldered taped off and secure!


 



Here's what the Walkman runs off now, an interchangeable 14500 3.7volt -1200mAh battery, there are others at around 2300mAh I'm going to try. Keep in mind again you do not need two batteries, this was just the best case I could find and I've altered the wiring so the case works with one. You could even try the next size up 3.7volt 18650 batteries which go up to 4000mAh, I simply used what batteries I had here for the time being.

 





And there you have it, one Walkman I've been listening too all afternoon.

See, because the original Walkman battery was 3.7v 1280mAh, we're basically using exactly the same thing (minus 80mAh in this case) so there's no reason why it shouldn't have worked. Best of all, if the Walkman goes flat you can simply hot swap to a fresh battery, hell, you can carry 4-5 if you want in those battery storage cases and take it camping. Now the Walkman can live way past any internal batteries life span. Keep in mind when you connect to PC for file transfer the battery still will not charge, this must be done externally with a 3.7v battery charger.

Run times with 1200mAh 14500 battery are being tested and so far proving well.

Now that is awesome.

 Good work there. :beerchug:

I've ordered these 2300mAh batteries. Knowing Chinese batteries they won't be exactly 2300mAh, but hopefully a little more than the 1200mAh currently in use.

http://www.ebay.com.au/itm/251609888181?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Everything is working well though. Battery percentage works with Android Battery Mix app and we're losing about 10% every 2 hours simply playing music. Wifi works, apps, everything like a normal Z Walkman. The only thing you might lose when switching batteries is the time / date, possibly the brightness setting (we will see).

From something about to go in the garbage bin no thanks to Sony, this is a good outcome.

I have another idea, why not use the empty batterybay for another battery and connect them in parallel? double the running time.

What do you think?

I had thought about it, though I don't exactly have the right connections to add a second battery to that casing and hold it 100% secure.

 If anything down the road I might change over to this casing linked below using the slightly larger 18650 battery rated at 3100mAh.

http://www.ebay.com.au/itm/201142854115?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

That battery is Panasonic branded and probably much closer to it's real life specs.

As it is atm, the 1200mAh UltraFire batteries are looking at getting about 12 hours (just rough guess atm) of FLAC per charge. I have two atm.

It's working very well though and I'm super happy about saving the Walkman. I will keep reporting in with updates.

Thank you, I'm pretty chuffed myself. Proof a Z Walkman can be brought back from the dead.

Everything still running fine here and I have a small update.

When you change batteries you don't lose any settings, this means brightness level, screen time out, sound settings (for example turning off key sounds), volume levels, the Walkman retains everything I can see, including continuing where you left off and resuming. Removing the battery and changing it (at least in just 30 seconds) doesn't seem to effect anything (except the time) .

Could be worse.  Wish there were subforums for devices, this really should be stickied!  

Maybe OP can revise?

 

My Walkman Z may have a faulty battery.  Not sure how it is configured, but it drops from 100%>80% really fast and gets around a few hours of usage before needed a charge.  Could be a calibration issue..

 

Might have to put mine on life support like yours, but it would be a damn shame because it looks so sleek :(
