Iriver H10! Help me please!

[llamadude]

Somebody please help me. My iriver h10 has been working fine until about 6 months ago, when rockbox refused to respond. I got my hands on another board, and they look the same except for a tiny internal battery.  The tiny battery looks corroded and dead.  Does rockbox utilize this battery in any way? Does this battery poser some of the controls?  The original firmware works fine, but it's no rockbox. Please please please help me. I miss my rockbox.

If you're talking about the 5/6GB version, that battery supplies power to the RTC chip when the normal battery is taken out, this keeps the date/time from resetting when you take the battery out. Try to find another one like it an connect it to see if it helps.

Where would i find such a batery? anyone know?

ps: does anyone have a bricked h10?

pss: ive got a h10 touchpad for whoever needs one.

What does the battey look like? Is it a small, silvery, "cell" battery?

See if you can take it out and read off to us any markings you see on it.

Have you tried booting into the original iRiver firmware to see if it isn't a problem with Rockbox rather than your H10? If the iRiver firmware works, I'd try rolling back your Rockbox to an earlier build.

Yea, it's one of those tiny, roud lithium batteries. The kind you find in watches. In fact, I have my broken H10 right here, let me check to see if there are any markings. It says: 3.3V 022F(or E) LNA. I'm guessing LMA is the company, and 022F(or E) is the model. It's about 6mm in diameter.

EDIT: Sorry about going off topic, but does anybody have a 5 or 6GB H10 hard drive they'd be willing to sell to me? I can't find one anywhere.

yes! abso - freaking- lutely!

i just got another bricked h10 off of ebay, and i got the working hd!!

hey man, sure. give me an email at dont_take_my_food@yahoo.com

it works, its UMS, and it's already goot rockbox loaded.  ive got a TON of h10 hardware, (screens, touchpads, boards, etc,) but no battery.  ill send u that hd in exchange for that board of urs.

What's the point of having an HDD without a board? Nonetheless, I emailed you.

llamadude: Pop it out and take it to either a jeweler's shop that specializes in watch repair, your local drug store, or Radio Shack. You should be able to find a replacement in one of those locations.

You would need to desolder it, but that would be the way to go.

I should clear this theme since it wasn't cleared 5 years ago.

In iRiver H10 its not a backup battery - it's ELNA 3.3v 0.22F Coin Cell Capacitor.
So it's not a "model", but just voltage and capacity "printed" on the coin
3.3 Volts and 0.22 Farad (which is the same as 220000 MicroFarad or uF)
Coin has steel terminals that are welded to coin and soldered to the board.
Part numbel seems to be ELNA DCK-3R3D224
Dataheet you can get here:
http://www.mouser.com/ds/2/129/DC_DCKe-4234.pdf
It seems to be that this part has been discontinued by the Supplier with No Replacement at this time.
You can look for analog with suitable specs.
I don't think you could find such a part in jewelery. More probably you could order it in radio shop.

Part is of type of Electrical Double Layer Capacitors (ELDC) aka Ionistor, which have relative high capacity.
You can read theory in Wikipedia:
http://en.wikipedia.org/wiki/Electric_double-layer_capacitor

BTW:
Manufacturer stated in datasheet that: "Unlike batteries, unlimited charge/discharge cycles; ideal for solar watches, solar calculators, solar remote control units, camaras and the like."
However our capacitors "look corroded" after a few years. As I realised, this "corrosion" is just dried up elctrolyte leaked from the capacitors due to overvoltage or most probably normal wear. For compare I have button sized Lithium accu in my watches (almost the same as RTC backup) which declared to work over 10 years (it works already over 5 years and still be OK... for a while .

If you can't find rare suitable ELDC you can replace it with 3V lithium button cell, but with DIODE(!!!) to avoid battery chagring by device!
