Hi Dave,
I believe your response to the newspaper should be along the lines of "when I get a Batteriser to test, I'm happy to be interviewed."
Only then can you be confident of the outcome.

Maybe I don't get the irony, but of course you can be confident before you have a Batteriser to test, because of physical laws and technical facts, like the bullshit that a boosted battery suddenly shows 100% full in a wireless keyboard. For all we know, and not the surpised user, it could suddenly die the next minute.
There should be a xkcd.com comic about it

panel 1: Mac keyboard with normal battery, level shows 10%
panel 2: zoom: put the Batterieser sleeve on it and back into the keyboard
panel 3: level shows 100%, stick man smiles, dumb comment from him
panel 4: one minute later: level shows 0%, clever comment from the woman from the back
