Getting more miles

[Craigrrr]

I bought a 2014 late Sept. It seems most every time I leave the charger on overnight, I get 76 up to 80 mile range . I was wondering if the battery might have been replaced before I bought it and how could I check if that is the case?

79 miles after last night

The number everyone wants is energy-to-empty (kWh). The miles of range can't tell us energy capacity without knowing the Wh/mile it's using to give that estimate, using one unknown to determine another unknown. The range changes because the Wh/mi average is updated as you drive, making the range estimate even less useful for estimating energy capacity.

You can ballpark the energy capacity by changing the view to show the Wh/mi gauge where it will show a blue "cup" around the gauge. That should be the Wh/mi it's using to estimate the range. Multiply those together and it will give the Wh of energy currently available. Divide by the current battery percentage (charging screen on the center UI) to get an estimate of the full battery capacity.

The better way is to check is to charge to full, clear a trip meter, drive to near 0, park and run the heater until you reach 0 and look at the kWh it shows on the trip meter.

The best way is to use an OBD adapter and ForScan to read out energy-to-empty.

Can we sticky this reply anywhere?

As for knowing it it's been replaced, there may be a label under the plastic in the back showing rev or manufacture date. Should also be able to pull that with ForScan.
