Best Battert Maintainer for Lithium Ion Battery
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.

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

Lots of the Battery Tender models have a Lithium mode. I have the 5A model and have been very pleased. https://www.batterytender.com/collec...ttery-chargers

Mhmm, CTEK is the OE for many car brands' battery maintainer as seen here https://mbworld.org/forums/coupe-roa...ml#post8548131

Just to wrap things up, for anyone still looking for a charger/maintainer for our lithium battery, personally, rather than the original one offered by Mercedes (a Mercedes rebranded C-Tek compatible with both lead-acid and lithium batteries), I would go for the C-Tek Lithium US, specifically designed for this type of battery
