Original Germany Siemens 6ES7971-0BA00 SIMATIC S7-400 PLC Backup Lithium Battery 3.6V 2.3Ah For PS405 PS407 Power Supply In Stock
6ES7971-0BA00 is the original German-manufactured backup lithium battery exclusively designed for Siemens SIMATIC S7-400 PLC series, compatible with PS405 and PS407 series power supply modules. With rated voltage 3.6V and 2.3Ah large capacity, it adopts industrial-grade lithium thionyl chloride cell, featuring wide temperature working range, stable discharge performance and ultra-long shelf life up to 10 years. When the main power supply of PLC cuts off suddenly, this backup battery continuously supplies power to the CPU internal memory to protect user control programs, hardware configuration parameters and process data from accidental loss, avoiding equipment downtime and production losses caused by program loss. It adopts standard AA cylindrical design, plug-and-play installation in the power supply battery slot without any wiring modification. The power module supports dual battery installation and battery low voltage alarm function; when the battery is insufficient, the BATT indicator light will alarm and trigger OB81 diagnostic interrupt of PLC. We supply brand new factory-sealed original Siemens parts imported from Germany, with 12-month warranty and fast global shipping.
