AA Cycler's Dream Charger
My dream charger, if it existed, would be a compact 4-slot fanless charger with 2 functions:
- CHARGE would charge AA cells at 1500mA and AAA cells at 700mA up to 1.45Voc (or 1.65Vc). Then it would gradually lower the current to keep the cell at 1.45Voc (1.65Vc). When the current dropped to 300mA it would stay at 300mA and would terminate on 0dV. No trickle or top-off charge
- REFRESH would first discharge the battery to 0.9V with 500mA, then it would charge it back up again
It would measure internal resistance before every operation.
It would have only 4 buttons, one for each slot. Short button press would toggle the display information (V, mA, DISCHARGE mAh, DISCHARGE h, CHARGE mAh, CHARGE h, mR), long button press would change the function.
The LCD backlight would turn off after 30 seconds and would turn on either after job completion or key press. After job completion it would stay on until battery removal or button press. It would flash on error.
If you know of such a charger please let me know :-)
