You got me curious so here is 2 refresh cycles test:
Swapped the bays of batteries 1-4 and 3-2 between first and second cycle
Batt | mV | mAh | 2nd reading | mV | mAh |
1 | 1425 | 872 | 1426 | 884 | |
2 | 1384 | 620 | 1386 | 628 | |
3 | 1418 | 1070 | 1433 | 1082 | |
4 | 1407 | 834 | 1413 | 819 |
The bays seem consistent and this is the charger.
I guess I have a bad battery in this batch but they were anyway going to be used for remotes, toothbrush, etc, so I guess that if that is the only bad one it’s ok for me.
