The title says it all. I always use Hilltop reserve, living on a hill. Five days ago I charged the car on my Level 2 Siemans Versa Charge, and came out later to find it still charging with four green blinks, and around 260 miles range. I unplugged it, and took a trip uphill the next day to burn up some KWs. I came home and plugged it in, Hilltop still active. I fell asleep and the car kept charging again. I drove a 130 miles round trip from 1000' to 14,000', to sea level, and back, and plugged in the car when I got home. The car was happy to charge past it's usual 213-215 Hilltop reserve charge, and I unplugged it at 217 miles. I'm taking it to Chevy next week to see what's up. I will report what I find out.
