battery box venting flow rate? [RE-wrenches]

[Ray Walters]

<x-flowed>

Well according to John Wiles's On Line course, we're not supposed to 
vent batteries to the outside at all, just make sure the room they're in 
is adequately ventilated.
Personally, I always liked the idea of directing the corrosive and/ or 
explosive gases away from the electronics. Maybe I didn't quite get what 
he was saying.
