I was dissapointed too. It was this way even with the original turbo 30.
The good news is that you are still able to match batteries. You just won't get the same numbers as are on the labels.
Plus, like I said, you will learn that company A's 500 is like company B's 480 (which may be your 430) and have a better idea of what you are buying from company to company.
