Doing less is inherently safer, in this respect reduced amount (of unnecessary) decision making is better.
If the FCOM suggestions work unaltered, it is easier just to follow them - same as Hans'. For us new crew = new start, irrespective of what has been left running.
pinteam: it is my personal belief the reason for the BAT check split between PM and PF during the cockpit prep is to cover for one of the guys actually not doing the job at all. On what is a survival-critical system in case of a larger failure inside the electrics. Good SOP would have such "recovery" features embedded.
That's where your company's way - whilst perfectly reasonable under the assumed state of things - falls short of the (slightly ignorant) FCOM regime, me thinks.
