Today I did my second range charge. The drive went great. We drove 237 miles round trip with 11 to spare. We had the A/C on the entire way and averaged 70 MPH. I was very pleased. The only issue is when I woke up and added the range (to an already charged car) it would not go past 261 rated miles. It kept saying 1 minute left to charge for about 20 minutes. We left with the 261 rated. Also (and maybe it's supposed to work this way) but the amp was only at 8/40 while it was trying to top off. It started much higher of course (39/40). Is it supposed to do that at the end of a charge? Should I be concerned that is never ended the range charge and stopped at 1 minute remaining? Finally, is 261 rated ok? I was getting 239/241 standard and now it's 238 regularly. My first range charge was 264. I have about 9400 miles. Thanks.
