im a bit new to the whole scrapping thing in terms of a business but i was wondering if anyone could chime in or give some thought towards yards and the accuracy of their scales. i recently dropped off two loads of lead batteries and both times there was a difference from what i had calculated. the first time i had found the weight online from a few different sources. and today when i dropped the second lot off one of the guys helping unload had told me what one of them weighed in at from the day before (confirming the sources online to be accurate). long story short, it seems like i was shorted about 10-7% on my weight. is this something that typically happens? how do you / do you confront a yard discretely if this happens? I'm dealing in the 10's of thousands of pounds range with these batteries so even a slight difference is costing me a lot of money. any help or suggestions would be appreciated.
