Charging 5 min in increased empty run the battery?

Hello, I’m new here and I didn’t find anything in the search. So my question: I have ne gs 500 e, which is registered over the winter. I thought to myself to rest over winter is not worth it, since I would drive from time to time… Well, like that is, too wet, too cold, too late got up and therefore already dark again –> not more driven since about 6 weeks. So I thought, do the battery something good and leave it 5 min. at 2000-3000 revolutions in the Lee Rlauf laden (nich ridden because weather is already pooping again). Do you think every 3-4 weeks such an action is enough to help the battery over the winter? Thanks for your answers
