Wanna know why manufacturers are reluctant to publish information on how to go about conditioning an AGM battery? Just re-read this thread. Here is a lot of pretty savy battery guys and look at the differences of "opinions"...
Manufacturers "appeal" to ten thousand times the number of battery customers and many of them need to have "This Side Down" embossed on their coffee cup.
They read the ad. The instant they encounter the least bit of techhie jargon, they screech "Other brand! OTHER BRAND! The one that says "Plug And Play!"
You know how these threads evolve. Would YOU like to be responsible to produce technical literature that would give do-it-yourself nerds shivers of delight as to the interpretation of the meaning of the word, "is"? Think about it.
Sales takes their fears of (killing sales) "overwhelming" customers with technical jargon to the legal department and litigation fear-mongers marching in tandem with the paisley and fluorescent tie crowd thunder into the executive meeting room and put the fear of god and the board of directors into the hearts of executive management. Any thought of producing comprehensive maintenance goes out the eleventh story window.
