Hi Guys, new to this group. I just bought an AMG GTS. I'd like your recommendations for the best battery maintainer for the car

 

I have several Noco Genius maintainers that have a lithium battery charge mode. I haven't used the lithium setting, but the AGM charge mode works fine for my vehicles. Ctek makes maintainers also with lithium charge modes, and some that are dedicated lithium chargers. Either brand has good reviews on the forum.

 

check Optimate1.com and C-Tek too (apparently, the MB genuine lithium battery charger looks lile a rebranded C-Tek...)

 

Ctek makes lithium ones too but Noco 5 can be used on agm and lithium if I recalled correctly.
