On a stocker, a battery has to be in stock location, no disconnect is needed. Add a battery in the trunk, disconnect is manditory.
which begs this question. what about the "factory" location[s] on several newer cars with the battery in the trunk or under the rear seat ? disconnect mandatory even though this is a factory location[s] ?
Not that its fast but some of the SRT's are... my wife's 2011 Jeep Grand Cherokee has the battery under the front passenger seat
