We were not planning on installing a level 2 charger to charge our 2018 Niro Plug in Hybrid since our daily commute is just a few miles each way, however on reviewing the user manual it states that level 1 charging should only be used in the case of emergency (no level 2 charger available). I also read on the 'Red' UVO eco app that level 1 charging is not advised because it can reduce battery life. I've done some research online and can't find any discussion of level 1 charging being sub-optimal for battery life. Is there something different about the battery in the Niro? Has anyone been charging the level 1 charger regularly (several times a week) and noticed significant degeneration in their battery?
