Accuracy
| Charge | Discharge | |
|---|---|---|
| 500 | 462 | 511 |
| 1000 | 939 | 1022 |
| 1500 | 1401 | 1531 |
Charges 6-8% less into the cell than it says. Discharge reads 2% higher.
The internal resistance readings of NiMH cells are also very good.
Liked
- 1mV voltage resolution (3 decimal places) - fantastic
- limits the charge current to 1000 mA when charging NiMH with impedance higher than 250 mOhm - TODO: TEST
Disliked
- flimsy build
Wished
- Refresh did only one DC cycle and showed both discharge and charge capacity
