Can you identify this battery?

Okay, I know this is very off-topic, but I also know that the Amiga community includes very knowledgeable tinkerers.

My 13 year phone's battery-backed up storage finally gave out. I took it apart and found this:

I can't make out all the details but I do see 5.5V printed on the side. This appears to be very similar to the leaky batteries used in old Amigas, just not as wide.

Does anyone know of a supplier? I suppose I could even do the watch battery socket hack if necessary. But since the original battery lasted so long, I would prefer to use the same part.

Thanks a bunch.

I did some more checking and found out that this is actually something called a "gold capacitor". Which explains the second number (barely visible in the photo) that reads "0.22F".

Digikey is one supplier I found, and this appears to be a good match:

Anyone want to confirm my findings? $2.06 isn't a bad price, but I do not know if a QTY of 1 can be ordered on this site. I think I will try my local electronics store first.

You're right on all those accounts (5.5v, 0.22F). They are the same as the PRAM caps in many Macintosh iBooks. And the suckers leak like Amiga NiCds! If you iBook suddenly stopped turning on or turns on intermittently, this could be the reason!

I've found them for your price (around $2-3) at Jameco which is local to me. I might have an extra one. I'll look to see if I still have it and if you don't find any, let me know. Shipping in an envelope should do it. I also have some crystals in case you're looking for any. Let me know.

Edit: Doh! yes, of course they're caps. Not batteries. Tired...

They are a special kind of electrolytic capacitors - reichelt.de has them for .66 €.
