I am interested to hear opinions about which charging methods are best to prolong battery life (reduce battery degradation). I found many suggestions, but have not found these questions discussed elsewhere. For each question, the amount of charge is presumed the same. 1. If a person's daily use is a small portion of range, and leaving each day with a full range is not needed, should they charge daily or occasionally? Charging from 75% to 90% every day, orcharging from 30% to 90% once every four days? 2. If a person has 80-amp HPWC available, should they choose to charge more slowly at 40-amps when there is no need for faster charging? Charging at 80-amps for 2 hours, orcharging at 40-amps for 4 hours?
