Does Agilitas use a battery?

Yes. Agilitas has a rechargeable battery that does not need replacing. Agilitas can be used for over 12 hours of normal operation (automatic mode), depending on the frequency of use, before needing a recharge. Agilitas will need to be recharged after 4-8 hours if the laser light is left on continuously (manual mode). The Agilitas indicator light will change from green to orange when battery power is running low.
