I have a Lightning reservation. Tired of gas stations and paying at a gas pump. Long time happy Ram Rebel owner. I asked about the battery warranty. It's 100k miles and 8 years. Cost to replace a battery set 15k to 20k. Anybody have concerns with this?

Not at all. Car batteries have held up much better than originally anticipated. Ford doesn't want to replace batteries, so you can bet the median life expectancy is much more than 100k miles / 8 years. Not sure where you heard that battery replacement price but the Mustang Mach E battery is a $26K part. The Lightning battery is bigger.

Thank you ChasingCoral for the reply. I asked the Sales Manager (where I have the reservation thru) from the Grove City, PA dealership and he replied:

Hi Andrew,
we don't have a data yet but we are looking at a range 15k to 20k for those batteries. Let me know if you have any questions.

I would doubt the Lightning battery will be cheaper than the Mach E battery.

I was watching several youtube videos last night on this very topic. Historically and on average EV batteries when charged properly tend to last about 8 years or longer while still holding about 70% of their rated capacity. The only exception to this seems to be the Nissan Leaf as they don't use any form of cooling on those batteries. Ford new what they were doing when they setup that warranty with the 70% capacity escape clause. They also mentioned that short charging helps to keep the batteries healthier than deep discharges followed by stage 3 DC high energy charging.

You should easily get 250k+ miles out of the battery pack, assuming that they are properly designed and build. Yes, there are examples like Nissan Leaf (no thermal management) and Chevy Bolt (they catch on fire for no apparent reason). Even Tesla had some batches where BMS would fail (not the battery, but BMS failure also makes battery unusable). But overall batteries are pretty reliable. Several Teslas have already made it past 500k miles mark.
