Benefits:
- Charging current quasi freely selectable (in 100mA steps)
- Discharging quasi freely selectable (in 100mA steps)
- Quiet
- External Power Supply
- Several batteries were repeatedly confirmed (weeks) with the same capacity, so built a good / accurate electronics
- Batteries with this device loaded contain more capacity than with AV4m loaded (about 100mAh battery at 2000mAh)
- Many programmme and settings
- Large buttons
Disadvantages:
- Dusty extremely fast, since no damper or similar available (clean contacts are essential for a battery-saving charging)
- Display lighting can not be switched off
- None of the selected settings can be saved and transferred to the neighboring cell
- There is no program which discharges directly and then again invites (you have to start program "unloading" after unloading program "Load")
Conclusion:
Good electronics at an affordable price. Who wants his charge batteries extremely gentle (eg load with only 300mAh and unloading) is very well served with the professional unit.
