I'm not exactly clear on this but the readings say 9.90v and 10.17v. I think a good battery is supposed to read 12v or above.

I could see maybe on the cranking test being lower is ok (10.17v)?

However, if the 9.90v is just the battery sitting there then I believe its supposed to be 12v or above.

The 14v on charging seems to indicate your charging system is fine though.

3 years is definitely short but have the battery checked out again.
