P0A80 on a 2007 HyCam

Did you change out the bad modules before reconditioning? I hope you did

 

Sriv,

Just looking at the second chart, it looks to me like you hit a homerun. (If not a homerun, at least a standing double). You've gone from a 3 minute discharge to about 6.5 minutes, at a similar discharge current. The discharge graphs for all the blocks are reasonably tight with each other. I don't think you actually had a true "failed" module, just excessively discharged. Looks like they livened up pretty well after you hit it with the Prolong AED. Now all you need to do is monitor it to track how it acts over the next several months. Throw in a load test now and then to see if any blocks are showing weakness.

 

The big delta you're seeing was due to the large current load drawn from the battery to start the engine. I wouldn't lose sleep over it right now. Keep an eye on your "bars" each morning when you initially get in the car and when you park it for the night. If you're going from 5 blue when parking to 2 red in the morning again any time soon, you'll probably need to work on an alternative plan. If it starts doing it months down the road, hit it with the charger again, or just get on a 3,4,5,6 month cycle to keep it as "alive" as possible.

 

I'll defer to experts on this but even HA says that 1 occurrence isn't a sign of problems, its consecutive readings.

"Maximum delta value between highest and lowest block is the most important parameter for battery health: high delta values suggests a weary battery. Delta values are significant only when repeated over a long time: the table counts consecutive samples where delta value is over the indicated threshold. Low counts are not an indication of a fault while high counts may be"​

That big delta is most likely from the engine start load.

Your consecutive readings report is looking much much better:
