Each unit comes with its own 1800 Milliamp Rechargeable Battery, which provides back-up power in the event that a main battery goes dead. Should this ever happen, the Siren unit will continue to monitor the vital system for between 48 and 72 hours (55 hour average) independent from the main boat battery.
