My previous advice regarding AGM batteries and to always use the Cold Weather Program (Snowflake Icon) is not necessarily correct. See this update:

 

Stuart,

I saw your request to delete in the original post #1 in this thread.

Deleting the first post in a thread deletes the entire thread so I have moved the content of your post #2 to post #1 and deleted post #2. Hope that makes sense!

So Stuart what is the recommended battery charge voltage?

 

 

Hi Robert,

All I know about voltage is that I plug one end of my CTEK MUS4.3 into a 120 volt US household socket and plug the other end into the little CTEK connector socket that's part of the wire that's attached to my 12 volt AGM battery. The magic CTEK box takes care of everything else.

I now set my CTEK MUS4.3 to normal (car icon) for the primary battery and small (motorbike) for the auxiliary stop-start battery.
