Can someone tell me what the best charging strategy is for prolonging the service life of a Bolt battery. I don't drive very far on a day to day basis so I have no need to ever charge up fully but I'm wondering if frequent partial charges is better or worse for longevity as opposed to infrequent charges to full, say once a week. I use only 120 volt charging. I know it 's not good to drain to zero which I never do, or to have the car sit for prolonged periods fully charged. It's the day to day short charges, say for 6 or 8 hours I'm curious about.
