Nissan LEAF 24 kWh Battery Upgrade at Leo and Sons EV Experts in Massachusetts

This video covers the process of replacing the 24 kWh battery pack in a first-generation Nissan LEAF, which is emerging as a viable way to extend the life of this veteran electric car.
Launched in 2010, the Nissan LEAF has been on the road for more than a decade now, so some early battery packs are starting to enter second-life uses (see links below). Although more recent EVs employ carefully-managed battery packs that are likely to outlast the rest of the car, the early model years of the Nissan LEAF saw significant degradation in some batteries. With a limited range of around 73 miles to begin with, LEAF models from 2011 and 2012 can't afford to lose a significant chunk of that range.
We visited the hybrid and EV auto repair experts at Leo & Sons in Lawrence, MA to check out the process and see a 2012 Nissan LEAF get a new lease of life with this switch to a more healthy 24 kWh pack. Hat tip to New Zealand-based ‪@EVsEnhanced‬, who created the translator kit for this process and have some great videos on their channel covering this popular model.

We also reference the subsequent 30 kWh packs that debuted on the 2016 model and 40 kWh of the second generation, as these packs can be retrofitted for earlier model years and boost range further still. These larger capacity packs are in limited supply as they're newer, but we can expect to see increasing interest in Nissan Leaf battery upgrades due to the relatively straightforward replacement process.

Thanks for watching! Couple of extra notes on this video: - The replacement battery was a recycled pack going into its second life. We don't know the story behind it, but presumably salvaged from a newer Leaf that couldn't stay on the road for other reasons. - Leo & Sons is the only independent auto shop we know of in the Northeast offering this service. There are a couple in northeastern Canada and several on the West Coast, as this enthusiast site maps out: nissanleafbatteryreplacement.com/ - Costs range significantly based on battery capacity, age, and availability of replacement packs.

Could you give a ballpark for reference? Also ballpark a new battery and new estimated range... (I have a 2012 Leaf, so....;-)

@@JohnHudert1 Range is heavily dependant on the health of the replacement pack, which isn't usually new but rather a less degraded option salvaged from a newer, healthier LEAF. Ballpark prices (from the Leo & Sons website) are as follows, though remember prices are rising and supply is limited: 24 kWh Battery $4,000-$6,500 30 kWh Battery $5,000-$8,000 40 kWh Battery $8,000-$10,000 62 kWh Battery $12,000+

On the one hand, the air cooled battery makes for a pretty simple (not easy, but simple) replacement. On the other hand, if it were actively cooled it might not have 60% degradation after 10 years. Either way great video and thanks for showcasing a company that's ahead of the game in electric maintenance!

Thanks! We talked a little about the flushing of coolant making things more difficult on modern packs. Still, the Bolt EV battery recall replacement process is only paid at 4.5 - 5.5 hours of labor by GM. I'm sure the reality means that's an all-day or overnight stay job, but it doesn't seem as far removed from the Leaf process as I initially thought.

Many of our partners like the team at Leo & Sons are already doing a great job of upgrading battery packs in older LEAFs to extend the life of these cars, but the supply of good replacement battery packs is a clear bottleneck that needs to be addressed.

EVs Enhanced is also planning to manufacture their "16 BLADE - The Ultimate Nissan LEAF Battery" packs to replace the old packs from the factory. Their packs come with a thermal management system - something Nissan forgot. They are based in New Zealand. Would be nice if someone in the States did that. Lots of Leaf owners, including myself, would love to go from 24kwh to 62+kwh.

Good to see shops like this springing up. I'm not aware of one in my area but it's only a matter of time. I didn't watch the whole video but I assume this was not a warranty repair? Any idea of cost?

@plugandplayEV 2 жыл бұрын

Right, someone on the Leaf forums maintained a global map of shops like this and sadly I think Leo & Sons would be the closest to you as well, Tom! There are several in California and up in the Pacific Northwest, as well as one in Texas, but it's not a common offering here. The cost seems to vary greatly because the supply of packs is limited. A 24 kWh pack like this is usually the cheapest and might start at a few thousand bucks, depending on where it comes from and transportation costs. 30 kWh is probably the sweet spot for upgrade value vs. price, as the newer 40 kWh and 62 kWh options are still in very short supply. At that point, it's probably cheaper to lease a new gen. 2 Leaf, at least with the deals they've been offering recently.

@wmalden Жыл бұрын

I live in Silicon Valley - tech central - and, as far as I know, there are no shops in the area that do Leaf battery replacements other than dealers who want $13,500 for a 24Kw battery. I have owned my 2011 Leaf SL for 12 years and it’s down to 5 capacity bars. I am on the verge of selling it to Carmax as the range is sufficient for only the shortest of trips. The car has 43k miles on it. Sad to see it go but it doesn’t make sense to me to invest big money in a 12 year-old car when newer EV’s are so much better.

@plugandplayEV Жыл бұрын

Yeah, that's a really solid amount of work from the LEAF though, and hopefully it will go to someone who only needs local range and can run it for a few more years to come. It's an expensive process to source and replace the packs at the moment, which sort of speaks to the longevity of the platform itself, but supply of new packs is very thin and the economics of replacement don't always work out, as your situation highlights.

@dttomsen971 11 ай бұрын

Why don't you have a trolly that can raise/lower the battery up to the car instead of raise/lowering the car on to the battery? - and I think the biggest question here is what did this cost? There is a saying of throwing good money after bad. After all this is a 10+ year old car.

@eamo234 Жыл бұрын

Interesting video. I found it a bit odd that they didn't raise the pack more when reinstalling it. Would have made the process a lot easier!

The replacement pack is only new in the sense that it's new to this Leaf. It has been used in a more recent model year Leaf that most likely gave it up due to some other reason taking the car off the road, but leaving the battery in good shape.

How much is to replace a battery? I have a 2012 Nissan leaf and a full charge only gives me 55 miles.

@plugandplayEV Жыл бұрын

Prices can vary quite significantly depending on battery quality and supply/demand, so it can be hard to peg the cost. At the time of making the video, the mid-point was $6,000-$8,000. That was a year ago though and supply has become more constrained, so the best bet would be to check in with Matt at this facility to see what their waitlist looks like and confirm current numbers: leosons.com/nissan-leaf-battery-upgrade-frequently-ask-questions/

Their approximate price range is $4,000-$6,500, including labor and degraded pack retention. And you're correct, it goes up in the thousands as you look at packs with better capacity, as they're more expensive and often harder to source.
