Is there any Battery inside the Tesys T to maintain the internal date and time during power OFF?

No, there is no battery installed inside the Tesys T to maintain the time during power OFF. But the TeSys T includes a temporary internal backup Power Supply mechanism. This mechanism, based on a capacitor, keeps the TeSys T internal clock updated to the real current date and time.

-The duration of this internal PS backup is between 20 to 60 minutes.

-When the external PS is interrupted, the date and time of occurrence is saved in permanent memory.

-When TeSys T is switched on again after a PS interruption, two cases :

  • The power shortage was shorter than the time for the internal capacitor to fully discharge : in this case, the date & time of the product has been kept “alive”. Means the PS interruption duration is compensated by the product.

  • The power shortage was long enough so that the internal capacitor became fully discharged : in this case, the date & time of the product when restarted is the date & time of occurrence of the external PS interruption.
