If my battery is 100% I only have 30mins left. This are my stats:

```
Energy : 17,6Wh
Energy when empty : 0,0Wh
Energy when full : 19,3Wh
Energy design : 48,8Wh
Rate: 34,6W
Voltage: 11,0V
Time to empty 30,5minutes
Percentage : 91,4%
Capacity : 39,5%
```

**My question is : Does the stats above really say that my battery just has 40% of what it should be after it leave the factory?**
