So better regression testing on new battery deliveries and better unit tests on the batteries themselves. That's a good item to add to the after action report. Now, what do you do to the battery to make the unit test? Shake it? Heat it? For how long?

I guess I'm just not seeing fault at GM here. Trying to get there though.

In this case you can x-ray it to see the problem. They were x-raying some, but not enough.
