CTEK Offers other excellent chargers for other type batteries. The short answer is no. **Q: Why does this "lithium charger" have a "desulphation" charging phase?** A: Good catch :) the diagram on this page is incorrect for this charger. Go pick up the manual (its online). Step 1 is ACCEPT.

I have mine for about two years without any issues. The CTEK is build to keep battery at optimum level, never over charging, but maintaining. You shouldn't have any issues leaving hooked during the winter. **Q: Do i have to buy multiple chargers for acid,agm and lithium?** A: You can use same charger for acid and agm but lithium charger is only for lithium batteries ## Customer Reviews ### ⭐⭐⭐⭐⭐ buen producto *by on Reviewed in Mexico 15 April 2022* exelente producto ,los uso constantemente ### ⭐⭐⭐⭐⭐ Great lithium battery charger. *by on Reviewed in Canada 22 May 2025* I bought this for my BMW F-90 M5 .
