Siemens 6ES7971\u20110BA00 SIMATIC S7\u2011400 Backup Battery<\/h1>\n
<\/div>\n

Product Overview<\/h2>\n
<\/div>\n
The Siemens 6ES7971\u20110BA00 is a dedicated lithium backup battery designed exclusively for the SIMATIC S7\u2011400 PLC series. It serves as an emergency power source for the S7\u2011400 CPU modules, used to retain user programs, process data, system parameters and diagnostic information during mains power failure or shutdown. With long service life, stable voltage output and industrial\u2011grade reliability, this battery ensures non\u2011volatile data retention for high\u2011end automation control systems in process industries, power plants, large\u2011scale production lines and critical industrial facilities.<\/div>\n
<\/div>\n

Main Functions<\/h2>\n
<\/div>\n
    \n
  1. Data Backup and Retention<\/strong>\n
    <\/div>\n

    Supplies power to the internal memory of S7\u2011400 CPUs to prevent loss of user programs, data blocks, recipe parameters and historical records when main power is cut off.<\/li>\n

  2. Long\u2011term Continuous Backup Power<\/strong>\n
    <\/div>\n

    Provides stable low\u2011voltage output for long\u2011time data storage under power\u2011off conditions.<\/li>\n

  3. System Maintenance Support<\/strong>\n
    <\/div>\n

    Maintains clock function and system diagnostic logs during power interruption for accurate fault tracking.<\/li>\n

  4. Plug\u2011and\u2011play Installation<\/strong>\n
    <\/div>\n

    Directly inserts into the designated battery slot of S7\u2011400 CPU modules without extra wiring.<\/li>\n

  5. Battery Monitoring Compatibility<\/strong>\n
    <\/div>\n

    Works with the S7\u2011400 system diagnostic function to send low\u2011battery warning signals for timely replacement.<\/li>\n<\/ol>\n

    <\/div>\n

    Technical Characteristics<\/h2>\n
    <\/div>\n
      \n
    • High\u2011quality lithium\u2011based battery cell with low self\u2011discharge rate and long shelf life.<\/li>\n
    • Compact form factor perfectly matching the mechanical interface of S7\u2011400 CPU housings.<\/li>\n
    • Wide operating temperature range suitable for harsh industrial cabinet environments.<\/li>\n
    • Over\u2011discharge protection built\u2011in to extend service life and avoid internal damage.<\/li>\n
    • Strictly standardized for S7\u2011400 series CPUs with reliable electrical matching performance.<\/li>\n
    • Vibration\u2011resistant and shock\u2011proof design for stable operation in industrial sites.<\/li>\n<\/ul>\n
