Description:

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

This file is writeable and can be used to set the assumed

battery 'full level'. As batteries age, this value has to be
|
|
|
|
|
amended over time.
