On a 2008 Gem with AGM replacing GEL, is it ok to use the onboard factory charger ? There are so many differences of opinions out there on this subject.  
Thanks a lot !

what is the difference of opinions ? some gem cars have an agm setting , so dont . For those that dont you can use the flooded setting . On many marine and auto mobile chargers thye have a setting for flooded/agm .  
a gem/deltaq charger will work fine on the right setting
