Gen One Battery Upgrade Options

Fri Mar 13, 2020 9:13 am

EV-Works on Bainbridge Island, WA has successfully upgraded Steve Marsh's (TaylorSFguy) 6 bar 2011 SL to a 40 kwh pack. Other tweaks include a MUCH steeper DC charge profile. Under ideal conditions, the pack would charge at full current (~ 120-125 amps) until 62-63% SOC before the current starts to drop. The car is now charging at full speed well past that. If you have a 24 kwh LEAF (any year) and was never happy with the 24 kwh range or simply want something you won't have to worry about for a much longer period of time the 2nd time around, you might want to read this.

This is certainly food for thought, as I am at 7 bars and considering selling the car, having Nissan put in a replacement batteryu or, now, this new option!

Well, its basically the answer to one question;

Are you happy with 24 kwh range and the likelihood you will be replacing that pack 8 years or so down the road?

If Yes; Right now, Nissan is offering a very good deal at $4500 with required exchange plus labor so "about" $5500 or so and you would be getting a better pack than you had before so it should hold up better and you have the advantage of the 80% setting.

If No; You are in majority and a larger pack is quite liberating. Yes, it will be more money but it will also likely be the last pack you pay for unless you plan to keep the car well past 10 years. No data, but guessing, after 10 years of normal use, I think you would still have more range than a new 24 kwh pack.

I haven't been able to find a 2018 battery with a few web searches for salvage/wrecking yards, so I'm not sure what the battery cost might be, that would be a big factor, obviously. But if it is anywhere close to a new nissan 24kWh batt, the decision is made!

Expect total cost to be "at least" 50% more. This is why my first recommendation if the 24 kwh range works is the Nissan option. It is a VERY good deal. So good, I do not expect it to last. If I had to guess, I would put the 40 kwh upgrade at $10,000 for parts, labor and programming.

But salvage prices will vary so best bet is contact them to see what they can do for you.

It shouldn't cost anywhere near that much unless you're paying someone $5k in labor to do the install. A few (very) wrecked 2018s appear to have sold for under $8k each a few weeks ago.

I've been thinking of this but even if you got an entire wrecked 2018 for $7k, it would probably take $500-$1k to transport it somewhere and $1k-$2k to hire to someone to do the swap. Add it all up and $10k is about right. You could save a few $k if you can do all the work yourself, including transporting a wrecked car, but that's a pretty big project IMO.

Labor for install only (owner supplied battery) is $1999 so thinking $5k is a bit high. As recently as last Summer, 40 kwh packs from salvage were easy to get in the $4,000-$5000 range. But they are hard to find at that price any more. There was one in Northern CA sold for $4500 a week or so ago but also saw several going for over $8,000 and yeah as someone mentioned, there is a cost besides the purchase price to deal with.

But anyone thinking they might be able to get this done for $7-$8k should start looking elsewhere. Now my price was a guess, nothing more. I can only repeat that because these are salvage without any set pricing, the price will likely vary. You need to call and find out.

Just to correct my quoted post: the 2018s I saw selling for about $7.5k had fairly limited rear-end damage and were probably being bought to be fixed up and flipped for $15-18k. As the wrecking sites hide sale prices after the auction, I haven't been able to catch the sale prices for any "very wrecked" 2018s. But it wouldn't make sense for an real wrecks to go for much more than $5k, assuming what's discussed here is still roughly valid.
