~60k miles
My Pilot won't start.
First time it happened battery was showing 6.5 V
I had AutoZone checked battery, alternator, and starter.
According to them they're all fine.

When I tried jump starting it, few times I had to wait for at least 2 minutes before it would start.

Most recent behavior:
If I disconnect battery and connect it back, the voltage starts going up, from 9 V to 12 V.
It takes about 20 mins.
When I try starting it, there's constant clicking sound, control panel flickering, and voltage starts going down immediately and rapidly.
It will go down to 6V within about 30 seconds.
After that I press start button (once) and all instruments go dead and nothing will turn on.

Ideas?

You need a new battery. The idiots at AZ did not do it right.
