| 5 | Description: |
| 6 | This file is writeable and can be used to set the current |
| 7 | coloumb counter value inside the battery monitor chip. This |
| 8 | is needed for unavoidable corrections of aging batteries. |
| 9 | A userspace daemon can monitor the battery charging logic |
| 10 | and once the counter drops out of considerable bounds, take |
| 11 | appropriate action. |

| 17 | Description: |
| 18 | This file is writeable and can be used to set the assumed |
| 19 | battery 'full level'. As batteries age, this value has to be |
| 20 | amended over time. |
