Hello 

I am in the planning stage of rewiring the boat and have decided to move from lead acid batteries to AGM.  On reading around the subject I understand that they should be charged at between 14.6 and 14.8 volts. The place I use for my alternators are not experienced in AGM batteries and the battery supplier just sells them.
Does anybody have any practical experience of charging AGMs with an alternator?  If so what voltage are you using.

Thanks

Sandy
