Dumping stuff hard on the scales can upset them.
Most work off a piezo load cell. Google it.
Dry or wet batterys? Just going off a bunch of numbers in a book is not accurate..
A local yard (the one I told the guy not to go to as he "will get ripped off") we went too.
I noticed they would look at the sack of metal, pick it up, move it around, put it down & weight it.
But there was something weird with their movements....
Then, one day someone tells us to "make sure the metals on the right hand side of the scales"...
Why? "Because the left hand side is damaged and weighs 1kg less."
So, I check it out, sure enough...... its a kg less... And the guy shifts it from right to left, weighs a kg less.
Did we go there again? guess.
Someone had smacked into the left corner with the
forklift.
Best thing to do, check your weights first. BTW you are not 'topping off' the batterys with water are you?
Scrapbuyers will deduct weight if you do that.
