Hey folks! I apologize for such a basic question and please feel free to point me to a thread, but, after reading I want to get a better feel for charging to 100%. I ran into a range problem when I saw my golf coach this week. In the future i will need to charge to 100% to see him. I am also Santa Barbara bound next week and would like to leave my house fully charged. Is the basic idea about charging to 100% to make sure you do not let the battery linger there too long? If so, does it turn into a guess on when to start charging so you hit 100% near the time you need to leave? Also. I have a 70D with a 14-50 charger. Any idea how long it would take to charge from 90 - 100 % ? Thanks!
