+
+
+This is the battery component that generates a 'battery' which corresponds to a level 1-4.
+- 1 - low, green (best case scenario)
+- 2 - medium, yellow
+- 3 - high, orange
+- 4 - critical, red (worst case scenario)
+
+Also accepts a label which can be made invisible.
+
+
+## Component usage
+
+### Low severity
+
+```js file="./BatteryLowExample.tsx"
+
+```
+
+### Medium severity
+
+```js file="./BatteryMediumExample.tsx"
+
+```
+
+### High severity
+
+```js file="./BatteryHighExample.tsx"
+
+```
+
+### Critical severity
+
+```js file="./BatteryCriticalExample.tsx"
+
+```
+
+### Default variant
+
+```js file="./BatteryDefaultExample.tsx"
