Battery Tesla or AC DELCO

At 4 years both our Teslas appear to have essentially the same range as new. Which is to say a bit lower than Tesla advertised but no worse

I started buying AC Delco, probably now made in Korea. Anyway, 9 years in my Kia Spectra, 7 years in our rarely driven ‘02 Accord, has another in there from a year or two ago. One that was in my wrecked Cobalt, still works but is sitting. Now one for the Cavalier that had a two year old premium Everstart. The place I get the AC Delco batteries from sells a lot of them so they refresh their inventory. And they are also cheap with my business account. Was $120 for the last one, got the better option they offer. But most have been under $90. Although prices have gone up everywhere throughout various product. Just saying, for whatever reason they have been the only ones I didn’t have to warranty out every 2-3 years. Maybe I’m just getting lucky with them for the last 12-13 years. But I got tired of SuperStart and Everstart batteries that I used to go for. Duracell had been good in customer vehicles.

I'm going to turn 230k miles on my 2018 model 3 tomorrow. The only time it has been to a service center is when the 12v battery died on a road trip. Other than that, I've put tires on it. I'm at about 21% degradation but everything still runs as it should. I'm hoping to get to 300k miles on the original battery.

My rec would be to find somewhere that sells AC Delco Gold batteries, that's what I use at my shop and they usually have a very good 42mo free replacement warranty and they're great batteries. As long as you don't buy walmarts brand, you're good. I've replaced like 8 Walmart batteries that were less than 6mo old in the last two weeks. No idea wtf those guys are doing.

Longest battery I had was from AC delco, lasted 10y! But apparently they are different now.

After 3 years, my Tesla Model 3’s battery range dropped about 7 to 15 percent, which seems pretty typical based on what others report. It isn’t catastrophic, but it is definitely noticeable for anyone doing longer trips.

My 2021 model 3 is also in for a battery swap. Furtunantely i still got warrenty. Only lasted 100k kilometers.

Yes, my 2021 battery died mid 2024. No warnings, no abnormal behaviour. Luckily it was still under warranty and the towing and repairing were free.

I recently had to sell my 2013 model s for scrap value because the battery was out of spec. Tesla wanted 25k to replace. It was right at 200,000 miles.

Worst batteries I've ever had the misfortune to buy. Both died within the space of 3 months and wouldn't put out any power whatsoever. No matter if I tried to charge them, it made no difference.
