Have not had much experience with Chevy Quirk, however the results of the battery upgrade were impressive. Seems instead of about 3.5 miles charge per hour on 120 volt plug, it now is approaching 3.8 plus, and the range is working much better. We took a ride to Acadia and back about 200 miles, we had 3/4 fuel gauge upon return we still had 1/4. Hilly drive on coast. I was pleasantly surprised, however expecting simular outcome. I expect the pack was thouroghly conditioned before arrival so not sure if it will have additional breakin improvement as this has been my past experience with lithium batteries. But, Thank you!
