I bought the CTEK Lithium charger. The Costco model above looks fine too.

It’s a little irritating honestly that you have to be careful on when to charge up these batteries and you have to avoid below 32° temperatures in charging them when you may need a charge the most — very bizarre. I wonder how the car is designed from the alternator standpoint to charge the battery when you’re parked outside/ somewhere cold? It’s very strange
I’m wondering what the official line is from BMW engineers of what the car does when it’s sitting outside in freezing temperatures— how does the battery get a charge from the car?

So I discovered with my CTEK battery BT monitor that the Lithium US charger was not charging at 13.8v initially nor maximizing at final step. Garage temp at 58-60 degrees. It stayed at 13.6 for hours, and eventually went to float.
If it was a temperature thing and in the manual as such I would not have taken the step to get a new one. …. and it went to 13.8v in step 2-3 as it should. Anyone else notice reliability issue with CTEK?
