My sarcastic laden reply was not directed at you Muddydogs. We have a faction on this forum who try their best to convince others that bubbling actually means boiling and the use of a hydrometer twice a year is as sinful as a nunnery panty-raid. All cyber-printing looks the same. Ideas from the Banjo player in Deliverance, can look equally weighty to proclamations by Stephen Hawkings. I gag at some of the "better ones" by banjo players. But what is not so funny is that seriously interested battery users can fall for the nutso ideas of the seriously under experienced "twanging" of Alfred E. Neumann logic.
