- How this rechargeable lithium ion battery works:
- Light will blink orange when it is low on power, and as you charge it, the light will be a steady orange. The light is green when the battery becomes fully charged and it should be removed from the charger. The green light is also present when the battery is in use. Do not attempt to charge the battery while it is plugged into the compressor. This battery takes 6 hours to charge for up to 90 minutes of running time, allowing for multiple treatments from a single charge.
