Battery - Deep sleep
Pierre CASOLI

The battery automatically enters Deep Sleep mode when it remains inactive (neither charging nor discharging) for a certain period. The time it takes to enter Deep Sleep state varies depending on the battery charge level:
 

Battery State of Charge (SoC)

Delay before Deep Sleep

≧ 80 %

No Deep Sleep

≧ 40 %

30 days

≧ 10 %

14 days

≧ 1 %

48 hours

< 1 %

10 minutes

When the battery is in Deep Sleep mode, the status LED flashes red when you press the button. 

👉 Purpose: This mechanism is designed to extend the battery's lifespan by minimizing energy loss and preventing premature aging.


💡 How to wake up the battery? 

 👉 Press the battery LED button for 3 seconds or connect to a charger.
