[quote name="corax"]You have absolutely no <a href="http://www.batteryuniversity.com/partone-12.htm">idea</a> what you're talking about. Lithium-ion cells do not suffer from "memory effect." Partial charging at lower-than-maximum current reduces neither life nor capacity. In fact, slight undercharging actually <i>increases</i> service life somewhat. Over-voltage is the only way to electrically damage a Li-ion cell during charging. It may be true (though I doubt it) that the USB spec doesn't provide enough current or voltage to charge this particular battery to maximum capacity, but this fact would have no deleterious effect on the health of the battery.[/quote]
