I have read most of the posts on charging and I completely understand that high levels of charge and/or high levels of heat degrade the battery quicker. I have a charger at work, which is only 14 miles each way, and I typically charge to 150 miles each day and get back with more than 100 miles the next morning. I do not yet have a NEMA 14-50 at home, but am awaiting a quote on an install. I do currently have a 110 outlet in the garage to give me enough miles to get back to the office, if need be. My garage temperature almost never goes below 50 and never goes above 90. My question has to do with weekends. I would typically charge up to 90% on Friday afternoon and deplete the charge over the weekend till I get back to work on Monday morning. Is there any harm to doing this, particularly if I get back to work on Monday in the 10% range? I have an 85D with just under 1,000 miles that I have had for two weeks.
