Last night the battery temperature was 60.8F. This morning I would expect them to be at ambient as the charger was turn off but I didn't connect and check.

Book time is 4.5 hours to 5.5 hours. I dropped off the car at 8:15 am and they called at 11:45 am to say it was done. They charged it on their DC fast charger to 100%

The guess-o-meter is ALL over the place. Started at 200 mile range and then dropped to 135 after driving 25 miles. Average mi / kWh dropped from 4 to 1 and then has been slowly increasing since. The Service Rep said it would take 2-3 full discharge / charge cycles to learn the new capacity.

It is most definitely a new battery pack. The old pack had a flat bottom from sill to sill. The new one isn't so fancy.




When I dropped off the car they had 17 batteries stacked up. When I picked up the car they had 22 batteries. Service Rep said they replace 4 batteries a day
