+battery [![Build Status](https://travis-ci.org/distatus/battery.svg?branch=master)](https://travis-ci.org/distatus/battery) [![Go Report Card](https://goreportcard.com/badge/github.com/distatus/battery)](https://goreportcard.com/report/github.com/distatus/battery) [![GoDoc](https://godoc.org/github.com/distatus/battery?status.svg)](https://godoc.org/github.com/distatus/battery)
+=======
+
+Cross-platform, normalized battery information library.
+
+Gives access to a system independent, typed battery state, capacity, charge and voltage values recalculated as necessary to be returned in mW, mWh or V units.
+
+Currently supported systems:
+
+* Linux 2.6.39+
+* OS X 10.10+
+* Windows XP+
+* FreeBSD
+* DragonFlyBSD
+* NetBSD
+* OpenBSD
+* Solaris
+
+Installation
+------------
+
+```bash
+$ go get -u github.com/distatus/battery
+```
+
+Code Example
+------------
+
+```go
+import (
+ "fmt"
+
+ "github.com/distatus/battery"
+)
+
+func main() {
+ batteries, err := battery.GetAll()
+ if err != nil {
+ fmt.Println("Could not get battery info!")
+ return
+ }
+ for i, battery := range batteries {
+ fmt.Printf("Bat%d: ", i)
+ fmt.Printf("state: %f, ", battery.State)
+ fmt.Printf("current capacity: %f mWh, ", battery.Current)
+ fmt.Printf("last full capacity: %f mWh, ", battery.Full)
+ fmt.Printf("design capacity: %f mWh, ", battery.Design)
+ fmt.Printf("charge rate: %f mW, ", battery.ChargeRate)
+ fmt.Printf("voltage: %f V, ", battery.Voltage)
+ fmt.Printf("design voltage: %f V\n", battery.DesignVoltage)
+ }
+}
+```
+
+CLI
+---
+
+There is also a little utility which - more or less - mimicks the GNU/Linux `acpi -b` command.
+
+*Installation*
+
+```bash
+$ go get -u github.com/distatus/battery/cmd/battery
+```
+
+*Usage*
+
+```bash
+$ battery
+BAT0: Full, 95.61% [Voltage: 12.15V (design: 12.15V)]
+```
