Back in the 60's Delco advertised their batteries were "dry charged" so they didn't sulfate sitting on a shelf not used/sold for 6mo or a year or more.
When they were bought, they were filled with acid and charged for the customer.
Well that fell out of favor because people wanted a plug and play battery.
the proper procedure is to fill them and let them sit 12 hrs, top them off, and
then slow charge for 24-36 hours or until voltage quit rising.
ppl didn't want to dink around or come back tomorrow for a battery.
Today there are motorcycle/sport batteries that are still dry charged,
but most don't go through the proper procedure for putting them in service.
It is what it is, I see both sides of the situation.
