I think that it would be informative and interesting to amplify and record the chemical noise of different types of batteries and then place this recorded noise at say +20 dB to the noise floor on a music recording and see how advanced listeners react to it's presence. 

Of course this assumes that the noise of batteries is a fair bit above the noise floor of the recording chain so that the recording and amplification of the chemical noise is even possible. Perhaps better to just run a recording device on the particular batteries whose noise it is you are trying to record, record nothing and simply amplify the noise floor of the recording which I imagine is primarily the battery noise.

If this did prove interesting then an idea would be to separate the wall AC from the equipment AC by a battery chemical cell rather than just regenerating the equipment AC with a Class D amplifier from the DC of the rectified wall AC  as the PurePower unit does when not in battery mode.

Of course if Romy et al find that the corrected PurePower unit works as well in non-battery operation as it does in battery operation then this is a far less compelling experiment but still I think interesting and not so expensive to undertake.
