He has multiple options.
- Abandon all hope. This has been demonstrated to be an exercise in futility. Grid charging/discharge produces equivalent results in far less time, and grid charging is going to be needed for continued reliable operation.
- Suck it up and buy a replacement pack. Most if not all of the sticks in that pack are likely bad. That's how Honda rolls.
If he truly prefers violently piercing his sack repeatedly with a pickaxe, then he has the following options:
- Stop using a pathetic toy to try to test high current cells.
- Split the cycle into individual operations, so the data doesn't get lost.
- Turn cap limit off and let the charge terminate via -dV (this requires a high quality connection such as ring terminals bolted to the stick - not alligator clips). Also good to set a temp limit of 50°C if he has a temperature sensor, but it needs to be strapped to the hottest cell.
I literally just put 11 Honda packs from a mild climate through reconditioning.
Zero good sticks. Many candidates would work with grid charging, and ALL of them had great capacity, but one or more cells in each stick wouldn't hold charge. |
Sorry for bothering you once more. It seems as though the cells are able to cycle via the setting you talked about. I have so far cycled two cells for 3 cycles and the results are unusual to my understanding,
Cell 1- Charge - 7735mah Discharge - 6589mah
- Charge - 7321mah Discharge - 6142mah
- Charge - 7181mah Discharge - 6058mah
Cell 2- Charge - 7405mah Discharge - 0000mah DEAD
- Charge - 7582mah Discharge - 6042mah
- Charge - 7212mah Discharge - 5873mah
Each cycle has a 20min rest period in between and is charging @ 2.0 amps. Cell 1 is clearly the better cell correct?
