I just bought a CTEK MXS 5.0. The manual indicates that normal mode charges "many AGM batteries". AGM mode is listed as charging "most AGM batteries such as Optima and Odyssey".

Which of these modes is most appropriate for the AGM battery in the F-Type?

 

I have been using the AGM mode on this CTEK unit for several years for the original equipment FIAMM battery (AGM) in the F-Type - no problems at all. I agree that the description in the CTEK instructions is confusing.
