Thank you, I will measure the motor current first. Meanwhile, I looked at the engine. It is a 24V DC motor and the user manual states that it draws 5W in standby and 600W when operating. No, there is no power outage. Maybe only once every 2-3 years. But I am the apartment manager and according to the apartment security rule, the garage door must work with the recovery battery in case of a power outage, but the current battery only opens and closes the door 2-3 times. If it is turned on and off 10-11 times with a single battery, it will not be a problem for me. Perhaps it would be most logical to switch to a generator system.
