I got the drive battery replaced in both my 2014 spark EV's under warranty. It took persistence and two dealerships but I finally got it done. Both the replacement packs are the LG Chen ones that were used in the 2015 and 2016 spark. The BMS was reprogrammed to accommodate the different cell voltages. Both cars were down to 60 miles of range and now back up to 80 miles of range. The warranty threshold is 39 amp hours below that the warranty kicks in. I managed to grab a copy of the internal warranty submission which states the battery should be at 39 amp hours capacity or above. I've got pictures showing the cell voltages of the a123 LFP pack and the new LG Chen pack. I'll try to answer questions as time permits.
