better after a few cycles.

On the ODB2 port and the SGII I find that it lags the battery post
voltage by as much as 1/2 volt. When your talking battery health
it's the post voltage that really counts. That is why testing cables
is a good idea. The test you want to do is called a voltage drop test

Here is a nice Youtube how to.

Also you can test grounds this way.
