It's mostly just me trying to nudge Hans, as I had earlier on in Post #31:

When I spoke to Hans last weekend at the Netherlands Meet, he acknowledged that there has been some discussion in that general direction...

That would be quite cool, this thread is a bastion of wisdom- I know what kind of rechargeables to use, and how best to open the little beastie. Damn the torpedoes, open the wallet, iQube will be mine.

...I dunno. It strikes me as "6 of 1, half-dozen of the other". Whether or not rechargeables are shipped installed in the iQube, it seems clear to me that the owner is gonna have to open that battery compartment eventually.
So why delay the inevitable? Is it not better just to learn the procedure straight away and feel confident & comfortable with it, than to dread having to do it cold, perhaps just a year or so down the road?

Ray Samuel does the calculations on his web site for one of his battery powered amps to show how the battery will last something like 8 years of constant use before needing replacement. I'm not into the techie side of things so I let this slide off my scales but if the calculations are straight forward the question is, how long will the batteries likely last? I don't know how much it matters if you learn how to open the thing after the first 100 hours if you're going to install batteries which last 8 years. 2 years or less between battery changes is one thing but 4 years or more between battery changes starts to influence the calculus IMO.

Reason: to clarify my writing
I would strongly suggest not to exceed the specification of 2.35mm outer diameter. A long term increased force on the female connector inside the IQube might damage this and as a result give a bad connection.
I will check with the designers and the supplier of the internal female what is allowed and then report back here.

hello, just to add about my previous post the 2.5mm plug when half inserted in the amp still moves up and down left and right and fits snug when fully inserted without putting pressure on it. i was assuming this would be fine and i don't want to mislead people with what i said, i myself will hold back on useing the plug until i hear back from you/someone here. thanks jeremy.
To add some info from the battery site mentioned earlier
1. Standard NiMH cells have an approximately life span of 3 years with increased internal resistance, lowered capacities, and higher self discharge with age. Cheaper brands may have less.
2. NiCd cells have about 5 year life span usually fails with internal shorts (complete failure) or excessively high resistance.
3. LSD NiMH cells currently have no data in this regard, they're advertised as having better longevity than regular NiMH cells. They've only been out for less than 3 years now. The oldest cells reported (1.5 years old) was lightly used and perform like new.
and
LSD [low self discharge] NiMH tech has dramatically improve the performance, longevity, durability, and cycle life too. However, it is new and relatively unproven tech. For general use, the Sanyo Eneloops LSD NiMH seem the very best and there seems to be no reason to buy any non-LSD NiMH cells these days
and
regular NiMH AA rechargeable batteries giving 10 shots in a digital camera, regular AA alkaline batteries gave 90 buy Sanyo eneloops gave over 400 shots on a charge!
While this data says nothing definitively about Eneloop AAAs, It suggests that they would have a performance lifetime of more than 3 years and maybe in the 4-5 year range. Assuming for the moment that's true, does it matter if you successfully opened your iQube 4 years ago and never since?
so I let this slide off my scales but if the calculations are straight forward the question is, how long will the batteries likely last?
