Finally, working at Radio Shack for 50 years doesn't make you an expert.
How does AT&T and Bell Labs strike you, Mike ???
And finally......AGM batteries don't gas in the conventional sense.
And even a conventional battery won't gas enough to be significant given the parameters in the video.
IF one has conventional batteries, you should ALWAYS check the electrolyte level about every 90 days, in normal use or on a maintenance charger, even an automatic one.
If you really cared about his, Mike, you would do some serious research about what is likely to happen to large batteries if they are subject to ~15 volts/ .75 amps for a couple of hours a day.
The truth is nowhere near to what you and the video is claiming.
