I recently purchased an iBook G4 off of eBay. The iBook itself is a very nice sorta retro computer, good for web browsing with TenFourFox too. However, the battery's serial number begins with 6C548, which is in the range of first-5-digits on this page https://www.apple.com/support/batteryexchange/2006/faq/us_body.html. However, it says "ending with S9WA, S9WC or S9WD", while the other serial number ranges do not have an "ending in" part. Mine ends in S9ZD. Does this mean my battery was not affected? They are not clear on that, only stating "if the first 5 digits of your serial number match, get a replacement battery immediately blah blah blah". Any advice is appreciated!
