Battery Tesla or AC DELCO

I had a 12v battery give me a low voltage warning and they just came around and changed it.

My 2007 Tahoe still had the original AC Delco battery in it when I traded it off in 2019. Still turned the engine over like new.

Just recently replaced the 9 year old AC Delco battery in my Impala when it finally went. Was working just fine, then went to start it a few days later, wouldn't crank.

It’s a battery. It doesn’t make a difference. Find an ACDelco one. They usually last the longest for the best price.

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.

I have a ‘21 (Dec 2020) M3 LR AWD w/19”. I’ve put 52K miles on it so far. Generally speaking, I’ve seen very little degradation.

All Teslas lose about 10% of their range in their first year. And then it levels off considerably after that.

Replaced battery in my 2012 Chrysler 200 - after being in car 12 years - yes original battery - bought car off show room floor. Replaced with AC Delco 580 CCA - as per manufactures specs - exactly 2 months to the date - battery absolutely DEAD !!!!!!

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