Battery Tesla or Duralast

The other one (duralast one) has a better cca and will perform better in the winter months.

It's a Tesla thing.

Tesla doesn't keep a buffer zone at the top end of the battery. 100% means 100% in a Tesla. Tesla advises to only use 100% when you need the extra range.

My tesla model y recommendation is 90%. I know lfp batteries are recommended to do 100% at least weekly. We do 90% but drive the car about 100 miles every work day so it doesn't even sit at 90% for very long, maybe 3-4 hours.

This is really straightforward to do. I replaced mine last September and was concerned about coding or needing to go to the dealer. My 2017 required none of that. Just take the old battery out and put a new one in. You'll have dash lights on afterwards, but all you need to do is turn the wheel all the way to one side and then the other.

I replaced mine in my driveway with a same size AutoZone Duralast Gold. With a coupon, I was out the door for less than $200. The car wintered outdoors at a Vermont ski resort and always started.

I JUST replaced my wife's 2013 Beetle battery with a Duralast from Autozone.

I have an early VIN 2020 MYP with 80,000 km; the diagnostic says 87%, so 13% drop in battery health. Range calculation at 100% SOC dropped 4.9%.

I don't want someone else's crusty ass battery. Charge times are already low and are plentiful (Tesla at least), I don't see the utility of swapping the battery out when I could stop for like 15 mins.

2019 model 3 SR with 10% loss based on full charge at 52k miles.

Don't do Duralast...they don't last.
