Modern efficient EV batteries are welded to be air and water tight, both internally and externally; this means replacement is tearing the car apart.There's too much going on around the batteries to allow drop out replacement. Hybrids, since they have much smaller packs, are often just conditioned by exposure to the internal cabin air, allowing for easier replacement of bad cells.
