li-ion akkus haben keinen memory effekt !!!
Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem.
das nenne ich glück - du kannst mehr als froh sein, daß dir dein akku (sofern das auch ein li-ion ist (bei ni-cd bzw. ni-mh mag das eine brauchbare lösung sein)) noch nicht abgeraucht ist...
Some lithium-ion batteries fail due to excessive low discharge. If discharged below 2.5 volts per cell, the internal safety circuit opens and the battery appears dead. A charge with the original charger is no longer possible.
However, if the cell voltage has fallen below 1.5V/cell and has remained in that state for a few days, a recharge should be avoided because of safety concerns. To prevent failure, never store the battery fully discharged. Apply some charge before storage, and then charge fully before use.
genau das passiert, wenn du den akku mit dem lämpchen bis unter die "todesschwelle" beförderst - das nenne ich grob fahrlässig...
