What:		/sys/class/power/ds2760-battery.*/charge_now
Date:		May 2010
KernelVersion:	2.6.35
Contact:	Daniel Mack <daniel@caiaq.de>
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.

Date:		May 2010
KernelVersion:	2.6.35
Contact:	Daniel Mack <daniel@caiaq.de>
Description:
		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.
