| This seems to be quite realistic. I think, in the average, my devices last for about 10-14 days. | This seems to be quite realistic. I think, in the average, my devices last for about 10-14 days. | ||
| + | ===== Deep discharging ===== | ||
| + | Sadly, no deep discharge protection is implemented. The Light gets weak, when one of the batteries goes below 0.9V, since the impedance of this cell increses. \\ | ||
| + | Once I measured nearly 0V of one NiMH cell, wich is not good. Hopefully the cell recovers. For now, I'm measuring every cell voltage before replacing it with freshly charged ones. | ||
