For the 2020 model years and onward, the technology and the capacity of the new battery aren't different from the old one. It's just that the replacement is validated to be free of the manufacturing defect that could lead to the fires. So you should feel safe, but you should not expect any changes whatsoever in terms of performance.

 

Battery capacity is measured in kWh, not "kw".

 

There he is again, our resident forum grammar police. LOL

 

After the battery was replaced and I was called to come get my Bolt, they had only charged it to 20%. I would think the dealer would have a fast charger on hand?

Not all dealers have fast chargers, although I think they should. When I picked mine up it was connected to a Level 2 charger, but I wasn't going to wait around for that. So I took it home with about a 30% charge. Once home I immediately plugged it in and charged to 100%, just to make sure they did the software upgrade correct.

 

I run my VIN every couple weeks but it remains “ remedy not available. “ I would be pleased to get a new battery, but I’m content to wait, just as long as I DO eventually get a replacement. Is every Bolt guaranteed a replacement ?

Every Bolt except ones built after they started making the "improved quality control" batteries.

I'm STILL waiting for my 2020 to be eligible for replacement. It pisses me off that they're selling Bolts to new customers but leaving their old customers high and dry. It's been well over a year that I've had a 20% range reduction.

 

FWIW our 23 EUV, built in January this year and sold to us in February, the day we signed papers the car had the charge on it that was put in at the factory: around 40 miles range on the meter. That was why we couldn’t drive it home that day. They don’t have a DC charger, so the car took around 11 hours to fully charge so we could drive 70 miles home. That’s why we had to come back to get the car. If not for that, we would have found the car, bought the car, and drove it home all in one afternoon.

 

I guess that brings up an interesting point about 66 versus 65 I assume there'll be a lawsuit on that.
It's possible that LG tweaked the chemistry very slightly or set software limits.

 

Nonsense. There are no federal requirements for advertised EV battery capacity.

 

My 2020 still has the original battery, the sticker on the pack says 64kwh. Is that what the original packs all have on the label? Where does the 66kwh come from?

 

Marketing wonks maybe?

I don't know if I necessarily need start a new battery thread, but here it goes.
Just had my chevy dealer replace the original 66 kw 2020 Bolt battery with the replacement battery being installed via the recall/replacement program. I guess I'm wondering what's the difference between the two battery types other than the newer replacement not subject to catching on fire? And, a new 8-year warranty.

Is this an entirely new type of battery they installed? And should I feel safe with fully charging my Bolt from now on? And did this upgrade/replacement actually fix the catching on fire concerns?
Just what else might be the advantages of the new replacement battery? Longer range? Better adapted to climate change i.e. outside cold/hot temp conditions?

I'm glad they replaced the battery with the recall but I was not expecting it to happen so soon. I figured I was far down on the list, and then out of the blue I got the call from Chevy Inc. Apparently, going by the vin number.
Plus, now I have a new full 8-year battery warranty.
After the battery was replaced and I was called to come get my Bolt, they had only charged it to 20%. I would think the dealer would have a fast charger on hand? But regardless, 20% was plenty to get me back home.
They also did the seatbelt recall fix.

The replacement battery installed by the recall is the same capacity as all the Bolt batteries installed since 2020 - 64 kwh nominal (some marketing types extend that to 66 based on technicalities; EPA range rating is 259 miles in the EV, 249 in the EUV). The difference between that and the pre-2020 batteries (60kwh, 238 miles EPA rating) is a slight chemistry tweak. The difference between the batteries used in the recall and the older ones (including those of 64kwh capacity in 2020-22 models) is a change in the manufacturing process to avoid the problems that cased the fires. New production since mid-2022 uses the new battery design done for the recall, so most 2023s and maybe a few 2022s are not part of the battery recall. Check VIN to be sure. All Bolt batteries are physically compatible - same case and same mounting points.

 

The new pack will have to be EPA rated as 65 kilowatt hour. Why the original pack and the current pack is being marketed as different I can't say. Like above maybe a bit too optimistic.

 

Does the 12V battery count for the other kWh?

I'm sure some technical reason exists. I just don't know it. GM may have said why at some point.

 

I'm sure some technical reason exists.

The more likely answer is that somebody told the marketing department they were going to get GM in trouble if they kept prevaricating.

 

Oh, and here's another pointer for the "66" becoming "65" not being a technical change. If you go to the GM Korea's website for the 2023 Chevrolet Bolt EUV (the link title says 2022, but you'll see 2023 on top of the page), you will see that it is still advertised as having a 66 kWh battery.

Scroll about half way down and you'll consistently see "66 kWh" value written in at least three places. EV certification listing provided by the Ministry of Environment (of Republic of Korea) also keeps the battery value of "65.94 kWh" for the 2023 model year EUV and EV models.

The 2023 price catalog for the Bolt EUV also shows the 66 kWh number.

https://www.chevrolet.co.kr/content/dam/chevrolet/as/kr/ko/index/e-catalogue-price-list/2023/02-pdf/price-list/apr/All%20line-up%20pricelist_202304_BOLT%20EUV-compressed.pdf

All the Bolt EUV and EV models coming to Korea roll off the exact same factory in the US as the States-bound versions. So there is little reason to think that the "66 kWh" Bolts sent to Korea have different batteries from the "65 kWh" Bolts sold in the US.

Therefore, it's just the GM marketing deciding to change the advertised capacity number in one region and not the other. The reason was never explicitly publicized.
