I know about the battery safety reserve required, however I can only work on the info provided. So if the info I get says it takes 8 - 9 hours to trickle charge the 30kWh Leaf I can only assume the time stated includes the battery reserve. Also I know the Leaf or any other EV does not let you go to 0% discharge so can only assume you are exaggerating to make a point. However your 14 hour trickle charge time using a 3-pin plug tells a story. In fact not a positive story as 14 hours is a long time and closely matches the 16 - 17 hours to fully recharge a 60kWh Leaf I mentioned in my post.
