All the batteries I tested were at 284 to 289. Being that you don't even no what the blue bread box is tells me you don't no much about testing. I can tell you that bashing all these supplier is not a good business practice and will affect your buying and sales. I am not going to bash you or your business or call you out. I am just not that type of person. What I do no is you charge WAY to much for batteries and we are not going to pay those prices anymore here in the USA.If you did not get 286-290 AH you got grade B. Grade A always are above capacity at a .3C test. 280AH = Grade B.
