About Battery Charge Graph

From Debian's package description

This package provides battery-stats-collector, a daemon which will periodically collect statistics about the charge of the batteries present.
It also provides a binary called battery-graph, which can be used to generate qplot graphs about the battery charge/discharge patterns over time.
Note: This requires APM or ACPI to be enabled and working in your kernel.

From Debian's description of the battery-stats package, under that package's license.
