battery pack capacity - grid charging
 

Hi,
I'm in the process of grid charging -> deep discharging -> grid charging and want to share my data and see if you have something similar available to compare.
I found these 2 reports, which are showing roughly the same results as I'm getting.

This battery pack was once replaced by Honda 8yrs ago and did just 60k kms since.
I've built a grid charger/discharger and I'm doing this through a built-in harness in the car.
The reason I started the whole process is that I observed during summer when AC is on and engine is auto stopped battery SOC goes down to 4 bars much sooner than few years back and quickly drops to 2 right after followed by the engine being started with disabled IMA for a while and starts to recharge the battery, as long as it reaches full SOC. Same happens on a highway after 1 or 2 hard acceleration. No errors though.
What I see is I could roughly get over 5000mAh out of the batteries. But still feels worse over the years.
Below table shows what I got during discharge.

I still need to get the car going and see if it got any better..

Any comments are appreciated.
