Here is my first test, Grade mode with a 1.5V Li-ion cell.
Grade CH1 1.5V Li-ion #1
CH1: XTAR AA 1.5V Li-ion 2500mAh (button top) (dark blue)
| Measurement | CH1 | CH2 | CH3 | CH4 |
|---|---|---|---|---|
| Start Voltage | 1.510 | |||
| Finish Voltage | 1.509 | |||
| Capacity (mAh) | 2453 |
Before starting this test, I charged the 1.5V Li-ion cell, took the cell out, selected Grade mode, and put the cell back in.
The graph shows what the XTAR VX4 did while using Grade mode:
- Charge the cell at roughly 4.9V 0.5A for a few minutes.
- Discharge the cell at 0.3A for a 8 hours. A capacity of 2453mAh was measured (pretty good for a cell rated 2500mAh while the room was about 9 C).
- Charge the cell again at roughly 4.9V 0.5A for 3 hours.
