It became apparent that 'battery' was a bad name, due to the above. It's
now /sys/class/power_supply/$devname and looks a bit like this...

	capacity:       91
	capacity_level: Full
	current_avg:    130
	health:         Good
	present:        1
	status:         Full
	technology:     Unknown
	temp:           2239
	temp_ambient:   5000
	type:           Battery
	voltage_avg:    6979620

... and this...

Soon, when I have it working properly... :)
