After the Warranty What Will the C-Max Battery Cost to Replace?

2013 Ford C-Max Energi

2013 Ford C-Max Energi – The high-voltage battery is in the rear beneath the cargo area.

If you’re considering buying a C-Max, you might be concerned about the cost of replacing the lithium ion battery when it fails.  A recent article in Autobloggreen said it wasn’t “all that expensive.”  The C-Max warranty is 8 years and 100,000 miles for the hybrid components, which includes the lithium ion battery.  In California, Arizona, Connecticut, Maine, Maryland, Massachusetts, New Jersey, Oregon, Pennsylvania, Rhode Island, Vermont and Washington the hybrid components (which includes the battery) are covered for a longer 10 years and 150,000 miles warranty (if your state passes the California emissions warranty, your warranty should be extended too).  Although the warranty isn’t for 10-years and 150,000 miles in most states, Ford does state that the battery will last more than 10-years and 150,000 miles.  Ford’s Chief Electrified Powertrain Engineer Mazen Hammoud stated in a recent Twitter question and answer that, “The battery is designed to last for the life of the vehicle.”

According to, hybrid battery packs are designed to last the life of the vehicle (about 15 years).  What if your battery doesn’t last?  The C-Max lithium ion battery for the 2013 Hybrid is listed on the official Ford parts web site.  The price is $3,510.38, part number 10B759.  This is a 1.4 kWh battery.  The battery for the C-Max Energi is the same part number and costs $8,546.87.  It is a 7.6 kWh battery.  Two factors may drop the cost to you.  First, you will need to drive the C-Max for more than 100,000 miles or 8 years, whichever is less before you bear the cost of replacement.  Once this warranty time period has passed, the cost of batteries should have dropped.  Second, Toyota gives Prius owners a “core credit” when they replace their batteries.  Toyota is currently charging $3,649 for a first- or second-generation battery, but the core credit is $1350 bringing the cost to $2,299.  Perhaps Ford will also give owners a core credit.  There is also a substantial labor cost for replacing the battery.  Last July, GreenCarReports described the experience of a Prius owner.  The total replacement cost with service was $4,400.  The owner walked out in shock at the price.  Later, the owner asked the service department for a better quote.  This time the total was $2,931.

According to Autobloggreen, “Consumer Reports has been impressed with the reliability of hybrid batteries and performance of the cars overall.”  Hopefully, C-Max owners are impressed with the reliability in 2020, eight years from now too.

  1. If you had an eight year old car with a failed transmission you would probably replace it with one from a salvage yard not a new one. Used batteries with varying milage at varying prices will be available much cheaper than todays estimated price new and cheaper even than the lower new prices expected eight years from now. Predicting a battery replacement eight years from now at todays estimated price new price makes little sense. Replacement can be done wirh a salvaged battery more cheaply by a non dealer service location. Battery replacements in hybrids are infrequent.

    • You’re right, many people would go to a salvage yard to get their replacement battery. I had an experienced salesman at a Toyota dealership bring up the battery replacement issue for the Prius. I think prospective buyers must bring this up frequently when they consider a hybrid. I was attempting to answer the question based on current data. I’ve bought four new GM vehicles with an automatic transmission in my lifetime. The transmissions in all of these died between 65,000 and 80,000 miles. It was a big expense to replace. This experience is most likely much worse than concern over replacing a hybrid/EV battery. Based on current information, I don’t believe battery replacement after the warranty should be a significant concern. However, I wish I lived in a state with the 150,000-mile 10-year warranty.

  2. I was a factory rep for Ford for several years. I promise they wouldn’t put a 8/100 warranty on a part this expensive unless they were very sure that the failure rate within the warranty period would be very low. Also, Lithium Ion tech is highly advanced and proven. I am totally comfortable with the battery portion of the car.

    • I think you’re right. They probably don’t expect many failures within 10 years/150,000 miles since many states require a longer warranty.

  3. The following is from the C-Max warranty:

    “Note: Lithium-Ion Battery Gradual Capacity Loss
    The Lithium-ion battery (EV battery) will experience gradual
    capacity loss with time and use (similar to all lithium-ion batteries),
    which is considered normal wear and tear. Loss of battery capacity
    due to or resulting from gradual capacity loss is NOT covered under
    the New Vehicle Limited Warranty. See your Owner’s Manual for
    important tips on how to maximize the life and capacity of the
    Lithium-ion battery.”

      • I have had my Energi for 2 yrs and 4 months with 105,000+ miles. The charge now only gives me 15 to 16 miles. I am hoping that the next battery I buy will give me 50 miles. That would make this car fantastic.

        • Agreed. We have only had our Energi for 2 months and 4000 miles. But our Nissan Leaf, it just lost a bar of capacity after 14 months and 14,000 miles. Am hoping that the Energi’s battery has better temperature regulation than the Leaf’s.

    • It would be interesting. However battery life isn’t the only problem. The trade-in value for plug-in vehicles isn’t going to be attractive. Tax credits, changing battery technology, the significant technology included in the vehicle in addition to the battery life left will result in poor trade-in values for plug-in vehicles. With attractive leases available, if you’re concerned about trade-in value, it may make more sense to lease (assuming you don’t already own a C-MAX).
