The manual says for extended storage leave the battery at a low state of charge. For a car driven only once or twice a week, rather than leaving it fully charged and plugged in...... Thoughts on plugging it in and using delayed charging so that it is fully charged before departure but doesn't sit for a week at a time fully charged. This is under the assumption that the more time the battery is full, the higher the wear.
Might be more of an issue on Gen2/ELR with the smaller buffers (aprox 2Kw top/bottom) VS Gen1 with the larger buffers (approx 3Kw top/bottom)
