Product Description for Siemens 6ES7971\u20110BA00 Backup Battery<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
6ES7971\u20110BA00 is an original Siemens lithium\u2011based backup battery specially designed for SIMATIC S7\u2011400 PLC system. It is installed on S7\u2011400 power\u2011supply modules (PS407 and PS405). When the cabinet main power supply fails, this battery offers stable standby power to retain CPU program, data block, hardware configuration and system clock data stored in RAM memory. Without this backup battery, all runtime data will get lost after power\u2011off. This battery is widely used in petro\u2011chemical plants, power stations, metallurgy workshops and cement factories adopting S7\u2011400 controllers. It is a replaceable consumable component with fixed service life to ensure data integrity for long\u2011term industrial\u2011site operation.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. RAM Data Preservation\n
    <\/div>\n

    It supplies power to CPU internal RAM after mains power is cut\u2011off. Program parameters, production set\u2011values, fault records and runtime variables can be stored safely.<\/li>\n

  2. Real\u2011Time Clock Maintenance\n
    <\/div>\n

    It keeps the system real\u2011time clock running normally during power\u2011failure periods so that time stamps for alarms and historical data remain accurate.<\/li>\n

  3. Low\u2011Battery Monitoring\n
    <\/div>\n

    The power\u2011supply module continuously detects battery voltage. If the battery capacity declines below threshold value, PS module triggers LED warning and sends diagnostic messages to S7\u2011400 CPU for timely replacement.<\/li>\n

  4. Short\u2011circuit Protection\n
    <\/div>\n

    Built\u2011in safety circuit prevents short\u2011circuit current outflow to avoid damage to PS\u2011400 internal circuits.<\/li>\n

  5. Easy Replacement Design\n
    <\/div>\n

    Users can change the battery while the PLC system is powered\u2011on, which avoids shutdown and production interruption during battery replacement.<\/li>\n

  6. Compatibility Matching\n
    <\/div>\n

    This battery works with all standard PS405 and PS407 power\u2011supply units for central racks and expansion racks of S7\u2011400.<\/li>\n<\/ol>\n<\/div>\n
