Stupid guys here in Isb mostly don't do the initial charging. They would simply add electrolyte prepared by them (upto the level much higher than the maximum line). If someone inquires about charging, they say that keep the car running for atleast 15 mins and the battery will be charged.
Same happened with me when I purchased AGS battery last year. Luckily, my last battery in charade lasted 3 years and still was going strong when I sold the car. The current battery, I haven't even added a single drop of water/electrolyte for last 1 year and never got any problem. (I do check the electrolyte level regularly, though).
