Dear Mr Kidsolo ,
thank you, for your inquiry to the Technical Support
Here is the answer of your question.
Is the S7-200 Power off and you remove the battery.
1. the Program code will be saved forever in EEProm
2. the Backup (super cap) will be save the Counters and the Internal memory bits Stored on power down
The time for the Backup (super cap) you will find in the technical data see attachment "S7-200 Battery.jpg"
