Wow Steve! I never though of that. So if a small business has a couple of automobiles (like construction contractors), would they fall under the TRI reporting legislation when they buy replacement car batteries or another car that has a battery in it? Come to think of it, the batteries in my diesel pickup truck weigh at least 50-lbs., and it uses two batteries! Ryan Grant > -----Original Message----- > From: Stephen R.
