Those values are the power remaining in the battery in percent, and the charging state as a numeric value as displayed in the following array.

Value	State	Description
1	Discharging	We are using the battery
2	Charging	We are charging the battery
4	Critical	Something really weird, but what
7	Not present / max	Another unknown state
