Internal Reserve Battery

Internal Reserve Battery

Each Siren Marine unit comes equipped with its own reserve Lithium-Ion battery, which provide reserve power in the event that the main battery dies. Should this happen, your Siren Marine unit will continue to monitor the boat’s vital systems for an additional 48 hours independent of the main battery. Rest assured knowing that you can still monitor the vital systems on your boat, and track its movements even with a dead battery.

you deserve peace of mind
