LeftieBiker said:EVs are perfect candidates for Lithium starter batteries since they almost universally have "phantom drain" from telematics and Lithium batteries don't care if their charge levels fall below 50% (unlike lead-acid).
They do care very much, however, if their SOC falls below 10%. That's why I don't recommend them: an expensive lithium battery can get killed dead just like a cheap SLA battery, and then cost several times as much to replace. Lithium can be a good solution for people who are actively involved in maintaining/monitoring their cars, but not so much for those who want to just drive the things.
Sorry, but I don't think it's reasonable for a starter battery to fall below 10% with even the Leaf's charging algorithm. A common failure point for lead-acid batteries is 50% SOC, which is a far cry from 10% (which I don't even dive my main battery down to).
