Service Life Management:

It is the responsibility of the end user to monitor the usage of the cell to ensure it stays within the design specifications. Regular impedance tests and recording should be done. The use of the cells should be terminated when the internal resistance exceeds 150% of a new cell or when 70% of the design capacity fading has been reached. Failure to comply with this requirement, will void the 1 year warranty on the cells.
