Is the spare battery easy to use when the domestic elevator is out of power?

Easy to use. According to the inquiry, Fang Tianxia official website shows. The elevator battery is used to provide backup power for the elevator system. When there is power failure or power failure, the battery can provide enough electric energy for the normal operation of the elevator. The battery can also be used in the emergency rescue system of elevators. When the elevator breaks down or people are trapped, the battery can provide electricity to ensure the safety of passengers. All domestic elevators have good backup batteries in case of power failure. A domestic elevator refers to an elevator installed in a private house and used only by a single family member.
