I tested one of the clone cells, I set the same discharge rate as the spec sheet for the 4 cell 12 battery that this cell came from.
This was just a rough test to give me a ball park idea of the state of the cell.
The difference in my test was:
Battery was only at 90% SOC
I set the tester to stop discharging at 3.00V
The 3 year old 170Ah cell at 90% charge gave 149Ah which is roughly 165Ah allowing for SOC.
So after a 15 hour at a constant 10A discharge the 170AH cell was 165Ah @ 3V
I will do another Cell test from 100% SOC and at a higher discharge rate today.
FYI Here is the discharge curve. Apology for poor quality conversion.
