Found another source that has a more manageable shipping cost to Canada. It's supposed to be $8 for anything under 5 lbs, customs-cleared, so no customs charges. I'll wait and see if that's the case after I receive it.
Yesterday, I received the new cap and replaced. The problem I ran across is the unit didn't turn on when the cap was in, but turned on with it removed. Since I ordered 2, I replaced the 1st one with the 2nd and still the unit would not turn on. Now with the cap removed it still will not turn on. I have checked the "lock all" switch and it is not engaged. The unit power button lights to orange, when first connected to the dock, then changes to green. I have checked everything I can think of with no success. Anyone have any ideas? BTW does the isolation pad serve any purpose?
For those in the UK (without access to the low cost super-cap);
My rechargable lithium cell is working fine and has been for months.
[Edit]
If there is sufficient interest in replacement super-caps (here in the UK), I could probably arrange a bulk-buy (say 20) from either Mouser or Farnell. Send me a PM if you're interested

I have just changed my backup batt with the exact same one that you used from cpc, but it still does not work, if I test the voltage to it with the battery in its 2.6 v. But as soon as I remove my battery the backup batt winds down to zero in about 15 secs. Do you think the backup battery is a duff one and to try another one.Or could it be something else .
I haven't tested the hold-up time of the lithium rechargeable (I usually swap out the battery immediately), but 15 seconds does seem to be too short. Make sure you give the cell a good few minutes to charge before testing.
Might be worth swabbing the area around the battery with isopropanol (or other circuit board cleaner) just in case there's some conductive contamination shorting-out the cell. I measured 2.8v at the capacitor pads with main battery in place, so it sounds like there's something dragging the voltage down on your machine.
At some point I may replace the lithium cell with the correct cap, but ATM it's working OK, so until I can get hold of the cap at a sensible price it'll stay.

Sorry I've only just notice this. Did you get it sorted out? (sound like a solder short - clean then area where you've been working thoroughly.)
The isolated pad is just a mounting for the super-cap.
Sorry it has a taken awhile to reply. I never did resolve the problem. I thought, at one point, that I inserted the cap backwards; positive touching the isolation pad, but I don't recall. I guess I should just get a new one. :(
My Axim has recently started to do this too - I don't have the tools (or the guts) to open mine up and replace the backup capacitor, but at least I now know what the problem is. Since I don't lose data (just date and time) - I'll just keep resetting it whenever I have to swap batteries (which isn't often thankfully).
:approve:
OK, I'm going to do this. But instead of trying to solder the battery to the pad, I'm going to use epoxy and/or Kapton tape to hold the battery in place. Getting the cap hot enough to solder that hidden pad is probably destructive.

Crap! I never thought mine would need this fix! I rarely change my battery since I usually don't run one down during the day and just recharge every night. I have 2 extra batteries and cycle them through every once in a while just to keep them in use. Swapped batteries this morning and the time reset - I've only had my PDA for slightly less than 1.5 years. I have no qualms about taking mine apart, but am not sure I will. It's not really that big of a deal to me to reset the current time for now, but that may change if I wind up having to swap batteries on a regular basis.

Hi,
I've developed a small app that I believe it could be useful with a non-working capacitor (like mine). Whenever you want to swap batteries, just tap an icon placed in the system tray, and answer yes to the confirmation message. Current date is then written into flash and restored on power up (adding one minute, which is more or less the time it takes to replace the battery and boot the Axim). It isn't extremely exact, but you can restore the date and time with an acceptable error.
Is anybody interested?

While investigating the continuing problem with my ax's backup cap/cell (see: http://www.aximsite.com/boards/x51-h...r-problem.html), I found the axim very temperamental if there was no cap fitted, if you have killed the cap by reversing it (unlikely but...) then it may be causing your boot problem.
