The AGM (and yes, lithium) batteries seem to work better with the Leaf's crappy 12 volt charging algorithm. It's been suggested that the car was actually designed to use a lithium 12 volt battery, and that makes as much sense as anything else.
Please elaborate on why you express this view. If it has merit, why hasn't Nissan started using an AGM in the Leaf as many vehicle
manufactures have? Yes, there is the cost issue, but at the OEM level, not that significant. Some have indicated that the Leaf's charging
algorithm provides too low of a continuous charging voltage, i.e. 13.1 - 13.5, which is more appropriate for an AGM. If this is the case,
i.e. an ideal charging voltage of 13.1 - 13.5 for an AGM battery, please provide a technical reference/paper indicating such.
Most data on AGMs indicate the ideal charging voltage is very similar to a lead acid battery.
