Hello Lotus; No, the backup battery of the S7-400 CPUs is not rechargeable, Look at the following warning: Automation System S7-400 Hardware and Installation Maintenance, section 7.2:
Rules for the Care of Backup Batteries You must observe the following rules to avoid hazards in the care of backup batteries: ! Warning: Risk of injury, material damage, release of hazardous substances. Lithium batteries can explode if handled improperly. Their improper disposal may result in the release of hazardous substances. Strictly adhere to the following instructions: • Do not throw a new or low battery into an open fire and do not perform any soldering work on the cell casing (max. temperature 100 °C). •Do not recharge the battery -- risk of explosion! •Do not open a battery. Replace a faulty battery only with the same type. Replacement batteries can be ordered from SIEMENS (for order numbers, refer to the “Module data” reference manual, in appendix C). This will insure that you are installing a short circuit-proof type. • Always try to return low batteries to the manufacturer or deliver these to a registered recycling company. Hope this helps, Daniel Chartier |
