So I have a laptop thats 99% stationary and would like to know how often to run it on battery to keep the battery capacity up for 4+ years. Right now I'm doing it once every 2 weeks. With my old Thinkpad T400 the battery held 70% after 5 years which I consider great, but it also offered the option of setting battery thresholds which even todays Thinkpads don't have; likely because the batteries are "smarter". So whats the deal with my current laptop, the latest mbpr15? Should I continue with the 2 week cycle or is there a different method to follow? Thanks.
