Battery charging efficiency

How efficient is a Li Battery in terms of discharge energy vs charging energy?

If discharged for 1second at 100mA, and then charged for 10sec at 10mA, does it end up where it started?

Ed,

I think you mean the efficiency of battery intake vs output. It should be 100% efficient. However, there is a loss from input power to charging power. In your example, more than 10mA is needed for 10sec to charge battery with 10mA charge current. Hope this help.
