RE: The question is:

Yes, Tony & if Fred or any others want to delve into battery noise measurements, they should leave that TNT article alone & look at some real research from NIST (national Institute of Standards & Technology) here:
http://tf.nist.gov/general/pdf/1133.pdf

"In this paper a measurement system capable of measuring voltage noise below -200dBV/Hz is discussed & it's ability to characterise experimentally high performance voltage references is explored. The results of such measurements on common batteries are presented......"

Unfortunately, LiFePO4 batteries are not covered but it does show an inverse correlation of noise to battery size - the lower noise comes from larger batteries


But here are some measurements on LiFePO4 batteries which might be of interest - no noise measurements but internal impedance measurements given if I could only understand Nyquist plots of impedances!
