What's the longest your car lasted after clearing P0A80?

About a month and 500 miles ago, I got many codes, but among them was P0A80. I cleared them all, just for curiosity's sake, and began to drive home about 80 miles away. To my surprise, nothing came back on that drive home. Even more surprising is that nothing has returned since.

It got me wondering if anyone else has experienced something similar. If so, what's the longest you've ever gone before P0A80 came back?

--for context--
The code salad came up after having parked the car for about 30 minutes. Prior to that, me and missus had just made a steep descent into a town where we decided to grab some coffee at a cafe. We live on Oahu, which can be quite hilly, if that helps to imagine the scene. Once we came back out to the car is when we got the codes. Not sure if it's related, but FOB started intermittently working right before the codes came up.

 

Nah, it's a rebuilt pack. Did it myself about 5000 miles and 1.5 years ago. That's not to say it's great. That's just to answer your question.

You're talking about the computer by the battery? If so, how do I check if it needs to be cleaned?

 

Oh, you're saying take off the computer cover and just check for obvious damage on the board and the pins?
