Z510 Battery problems

[theserpent]

First of all,I was watching a movie, battery was around 70% and it suddenly powers off, connected to charger and saw that the battery was 0 ( WTH?)

Then, I did a full charge,and noticed that the battery is discharging at an insanely slow rate.At 99%(it showed aprrox 3-5 hours rem), and was discharging at I guess 1% every 10-15 minutes which isn't normal, and then when it was around 70-75% it happened again.

I Do not know where the laptop bill is, whats the problem?Battery cell dead?

This is missing battery wear level.
