I see you were looking at our S600-30. Is that what balance you have? If so, then it's a great idea to see if you can tighten it up first before you actually replace them. See our 75-006 charging tool and the guide below.

If that doesn't work, then you're still ahead of the game since you'll need the 75-006 to install a new balance, anyway.
