I thought my battery wasn't holding charge ie poor range, in December so I had my local dealer run the tests to determine if it was faulty.

This involves fully charging and then disabling/turning off everything not needed eg heating/aircon, radio. And driving in a particular style across a variety of road types and speeds. If the car won't drive 16 miles under this test then they will look at replacing batteries under warranty.

My car did 18 miles. So no new batteries for me!

Worth asking your dealer to test the car. But it may be that it is cold where you are (battery range is reduced in cold conditions) and/or that when running on battery only you drive really hard.

I must say that one of the pleasant surprises of my 2019 Coupe has been the e-range. I regularly get 30+ miles when driving in eco plus mode here in Southern California. Can get even more if I fully shut off the air con.

Is your projected range at 18 km or is that your actual range when driving? Aggressive driving can bring down the projected range until you change it by taking it easy. In eco pro I can get 20 miles (32 km) or even a little more if I really try. What mode are you driving in and how do you drive? 18 km of real range seems too low and probably does mean a problem unless you are driving hard all the time. Careful driving should get you nearly double that.

Hi. Thanks for you feedback.
Indeed in cold days it seems itís stuck at 18 km fully charged. In hot weather I get 21 km. This is on startup. When I drive full electric in eco I get consistently more than that ( around 21 (cold) to 25 Hot) so it seems Iím lose to the limit. Anyway I hope the new battery pack can fit my 2015. Love the car.

Hi thanks for your reply. Itís, the projected range, since I get 3 to 5 more kms in ecoopro. Still I would really like to have 40 km as I suppose the coupe does.
