how to clear error P0A80

This can be really tricky if you didn't replace it with a brand new battery. That permanent code is a pain to clear on a gen 3 car, unless it's a new battery. Then you just drive it a bit and it clears on it's own

 

All you care is that that code now stays history not current or active that's it

 

if it's a new battery, you just drive it a little bit. Should be cleared in a couple days. I would give it an entire weeks worth of driving before you go back and complain.

 

You need to complete the Confirmation Driving Pattern to clear the permanent P0A80 code. Take a look at post #53 in this thread, https://priuschat.com/index.php?posts/3595679
