The device is a great help to me in months when charging my batteries. Some time ago I had bought the previous model and was so happy from ear to ear. It still works, but eventually it was not enough to be able to invite "only" 4 batteries at once.
This one is a little more powerful, but has the same operating concept:
1. Inserting the batteries (AA or
2. individual either for each shaft or select all together what to do:
2.a discharged, then recharge
2.b only invite
Is discharged 2.c cyclically / invite to any increase in capacity more registered
2.d capacitance measurement
3. (Ent) to adjust charging current
4. Wait until dispay "Full"
So you should already know something about communication, which discharging or charging currents may be used with the battery used in each case. One whatsoever automatic to determine the max. Charging current is not here. But if one looks at the matter and knows what you do, then the device is extremely practical and the battery will thank with a long useful life and durability. I am in any case, no battery in this device broke down, however, I was amazed to see what brings out a good charger like this one also out of simple battery.
I highly recommend this device to all those who are aware of the effect of (un) load currents and do not want to rely on an "automatic max. Charging current investigation."
