8 years or 100,000 miles on battery. 3 year 36,000 miles bumper to bumper.

Warrantied to 70% after 8 years, 100k miles. In one of the interviews I saw, I believe they said 70% of range and that was under the worst conditions possible. Meaning, daily extreme heat with exclusive DC fast charging.

Extreme cold is worse on EV batteries and range than extreme heat. That is concerning if they only mention heat.

I've never heard a Leaf or Tesla owner complain of battery degradation from cold. You lose range/power, sure. However, the physical and chemical damage to cells is from heat.

Yeah cold only reduces the performance of the battery; it doesn't damage the battery. Excessive heat can damage the battery.

So if the battery lasts around eight years or 100,000 miles, what does it cost to replace the battery? Can we get a extra warranty to cover the battery for a longer period of time.

Don't know how much a complete battery replacement will cost. Maybe in the $20k ballpark? The battery on MME isn't a single component -- it can be opened by an EV trained mechanic and the mechanic can replace the individual modules that are contained within the giant pack. That can reduce costs if only part of it has failed.

Also, I'm guessing extended warranties will be available from Ford and third parties, like usual. Stuff like this: https://libertybellauto.com/coverage/

Actually I take it back... Maybe it's difficult or not possible to get an extended warranty on the battery. For example, Ford's own "PremiumCare" extended warranty specifically excludes the High-Voltage Battery and related cables. Lame.

The battery will last longer than the warranty. A new car warranty is 3 years or 36,000 miles but we expect the vehicle to last 3 to 6 times that amount. Not to say that the battery will last that long but I consider the warranty period to be the minimum battery life span not the maximum.

If one reads about battery costs per kWh, then one realizes Tesla is approaching $100 per kWh cost. Meaning about $10,000 for a new 98.9kWh Mach E battery--ie. plus additional markup for profit. Then again, in 10 years will the cost be $50 per kWh?

If Ford considers the battery to be in good health until 70% capacity, then with normal use and SoC kept between 20-80%, the pack will outlast the car.

You can conservatively anticipate 1200-1500 charge cycles if kept in the 20-80% range. If a single cycle is the equivalent of 270 miles, then you're looking at 300,000-400,000 miles.

LG Chem is supplying the batteries to Ford for the Mustang Mach-E. The Bolt EV uses these same batteries and per large data analysis, degradation matches Tesla's.
