It's balogna articles like Winche's that gets all the weird crap that shows up in these forums started. Heck I read in RCM years ago an article by a "battery expert" that said batteries give off acetelyne gas when they are charging. As a battery charging electrician for 25 years in the submarine Navy who was responsible for maintaining the HYDROGEN detectors, I thought I had a pretty good handle on what happens when a battery is charged. I took him to task and was told in no uncertain terms that HE was an expert and I didn't know what I was talking about. Never read anything he wrote again.
