Tesla uses apparently Li-ion battery. I wonder why I han't experienced the same problem with other electronics using that same type of battery. For example, I had my fully-charged mobile stored away for approx 5 months without charging. When I needed it again, the battery was still usable.

A side-question: can somebody explain what happens to a Li-ion battery when it fully discharges? Why does it become a "brick"?
