Nissan: LEAF batteries should last 22 years

Data collected by Nissan indicates that a LEAF battery should last as long as 22 years, according to Francisco Carranza, Managing Director of Renault-Nissan Energy Services. Nissan monitors various parameters, including charging patterns and battery degradation, on the over 400,000 LEAFs it has sold in Europe since 2011.

Carranza did not discuss the issue of capacity loss, nor did he say how long the batteries would be suitable for use in a vehicle, but he did imply that Nissan sees second-life batteries as a way to boost revenue, as electrification is expected to cut into some of automakers’ traditional revenue streams.

“We are going to have to recover those batteries,” Carranza told journalists at the recent Automotive News Europe Congress. “Aftersales revenue will massively suffer from electrification,” Carranza said.

Nissan has a number of second-life battery projects underway. Last year a three-megawatt storage system using the equivalent of 148 LEAF batteries went into service at Amsterdam’s ArenA soccer stadium. Nissan also offers solar panels and battery storage for homes (a la Tesla) under the Nissan Energy Solar brand. “We are stepping away from the garage and closer to the living room,” Carranza said.

Nissan is also exploring ways to use EVs to balance supply and demand on the electrical grid. The company recently participated in a cross-brand V2G demonstration in Denmark. The LEAF is certified as an “energy plant” in Germany, Denmark and the UK, allowing it to be connected to the grid. “It’s working even better than we anticipated selling back to grid,” Carranza said. “The more you dig, the more you find gold. The amount of revenue and profit by using vehicles to provide services to the grid is big.”

    An early 24 Kw Leaf can be bought for about $6,000. In the UK 6Kws of battery storage for solar costs about the same! All i need now is an enterprising electrician to wire my old Leaf into my system and I’m off the grid!

    • Devin Serpa

      A better use for old batteries indeed.

    • Scot Dixon

      You are going to need a LOT of solar cells to charge that battery. Do you have a multi-acre estate?

      • Jens Kr. Kirkebø

        I have a battery at my cabin in the Norwegian mountains that are made from 2,33 Leaf-batteries (112 modules in total, 7S16P). I have no problem charging that from my 5,8kWp solar array, one sunny day will more than charge the battery from completely empty to 100% (which is actually 80% or so, since I want the battery to last at least 10-15 years).

  • Devin Serpa

    Not at all. Air cooled batteries lose too much capacity.

  • Tom Arnette

    Why does past Leaf battery performance say otherwise?

  • Fullxmoon

    It’ll last 22 years. Meaning it will possibly still hold some kind of charge? The battery may not explode, but given their past performance I wouldn’t trust it to be useful in an EV for more than 5.

    • wowlfie

      That’s BS. I have had my 2012 Leaf since November of 2011. Still going strong. More than 90% of it’s range showing. Proof naysayers are just that–naysayers. Someday this same car will find life on the grid. Mine!

      • Fullxmoon

        The batteries are dying in the extreme heat. Glad your EV is still working well in your climate.

        • Jens Kr. Kirkebø

          Mine alså works fine, after 7,5 years. Extreme heat is largely unknown here in Norway.

      • Roy Mintzer

        Having two 2011 Leafs; I’m a EV “orphan” (my quote!) when there’s no reasonable cost to replace with the same 24 KWh pack and absolutely no upgrade path to 30 KWh or beyond. I can not recommend Nissan if the car’s next home is landfill at under 40k miles of use.

  • SDT

    Yeah. It will last 22 years with 10% capacity. NICE!

  • LEAF Owner

    Nissan still owes me a new battery for the defective one in my 2011 Leaf.

    • Kent Taylor

      I had to pay for half the cost of a pack in my leaf, because it was 29 days past the 60 month degradation warranty. If you didn’t get a pack within the 60 month, 60,000 mile degradation warranty.,…your screwed.

  • wowlfie

    Which means 3 to 4 decades of useful life to 75% or so range. Pundits claim in 6 years batteries will fail and have been doing so. Yeah sure pundits. Go ahead and short EV stocks and lose ALL your money!

  • Ormond Otvos

    I was shopping for a used Leaf. There were many at 6000 dollars or less, but when I inquired, ALL of them were 7 or eight bars of life. That makes them useless for anything but local shopping.
    Nissan needs to do a warranty repair befor the Feds or state regulators force them to fix every one.

      Lol

      Nissan did have a class action suite against them. They were allowed to slip out of it by making a weak Capacity warranty of 6 years 4 bars lost 66% over 100K. They also control the bars in software and change things to avoid warranty coverage. PS note from website = Interestingly, the same study shows that Nissan’s more recent 30 kWh battery pack loses capacity more quickly than the older pack.

      Water-cooled (with that water chilled by A/C when needed) Fiat 500e I’ve seen as low as $6k in L.A. Usually there are 10 or more available for under $8k. Mine has 22k miles & goes 100 city miles/charge. Just make sure you unplug the false-positive-prone humidity sensor (easily accessible just right of the rearview) so it doesn’t keep turning on the A/C compressor.

    In 2013 my Brand new LEAF could drive 80 miles. Now, 75,000 miles later I can go 40 miles. It’s only been 6 years. How many miles will I be able to drive in 16 more years? 10 miles?

    That’s really not acceptable. It’s not acceptable now at only 40 miles range.

    That’s why I am going with LEAF380
