The Siemens 6ES7971-0BA00 is a 3.6V/2.3Ah lithium backup battery specifically for the SIMATIC S7-400 automation system. It is used to maintain data, such as program code and memory values, within the CPU when the main power is off. Lithium batteries can develop a passivation film during long-term storage, which may cause a temporary error message upon installation. The S7-400 power supply is designed to remove this film.
- Process Engineering:Complex control & large data for chemical/pharma/petrochem
- Manufacturing & Production:Short cycle times & high productivity for auto/electronics/consumer
- Energy & Utilities:Fault-tolerant monitoring for grid stability & power distribution
- Infrastructure & Water Management:Water dosing/pump control & railway/airport signaling/ventilation
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Memory Retention: It supplies backup power to the CPU's internal memory circuits, ensuring program code and system data are not lost when the main power is disconnected.
Preventing Downtime: By maintaining the PLC's configuration, it eliminates the need for manual reconfiguration or program reloading after a power cut, directly increasing productivity.
Maintenance Support: It allows the CPU to remain "hot" (retaining data) during scheduled system maintenance or hardware upgrades.
FAQs
-
What is 6ES7971-0BA00?+The Siemens 6ES7971-0BA00 is a 3.6V 2.3Ah lithium backup battery primarily designed for SIMATIC S7-400 automation systems, specifically for use in power supply modules to retain RAM data and parameter settings
-
Is the 6ES7971-0BA00 battery rechargeable?+No. This is a lithium battery and must never be recharged. Attempting to recharge it can cause an explosion.
-
Can I use a standard AA battery instead?+No. You must use the designated Siemens battery to ensure it is short-circuit proof and meets technical requirements. Using unauthorized batteries may void warranties.
-
Why does my new battery show an error (passivation)?+Lithium batteries can develop a passivation film over long storage periods. S7-400 power supply units are designed to remove this film automatically upon startup (depassivation), but it may temporarily trigger a battery warning LED.
