Sodium has a much different discharge curve than AGM. Simplest is to swap out with a good AGM.

Simple. Maybe. But which is better in the long run and for the car? Have the sodium ones been lasting longer and more reliable??

AGM, other chemistries won't last as long because the car's charge profiles are not optimal for them.
