The LEI SHI elevator batteries DJW12-7.0 and DJW12-4.5 (12V4.5AH) are mainly used to provide backup power for emergency lighting, communication devices, and control systems during power outages. These batteries ensure that even when the main power supply is interrupted, passengers can remain in contact with the outside world, and the elevator can safely travel to the nearest floor to release passengers. For more information, please contact customer service.
