vs
Battery Tesla or OEM BMW
The OEM battery is AGM. If it was an OEM battery it wouldn't be lead acid, at least here in the US. Not sure what you're talking about. I installed mine three years ago and have had no issues despite winters that range from below 0 to summers that reach 100. Fahrenheit obviously.
Pros: no issues for three years
Vehicle:
BMW
I have 2014 Tesla 85 s that I bought a year and half ago . It had 95,000 miles on it. It now has 117,000 on it. Original battery. Still going strong.
Pros: original battery still strong
Mileage: 117000 km
Ich fahre seit 8 Jahren ein Tesla Model S und habe jetzt 100.000 km drauf. Die Degradation des Akkus ist 9%. Ich habe zu 90 Prozent AC zu Hause geladen. Die ersten 5% habe ich innerhalb eines Jahres verloren, danach ging es sehr langsam. Ich habe den Akku nur vor längeren Strecken ganz voll geladen, ansonsten eher so bis 70%.
Pros: geringe Degradation, gute Haltbarkeit
Cons: anfänglicher schnellerer Verlust
Mileage: 100000 km
Der Akku meines Model Y 2021 mit 62.000 km ist bei 92 % SoH aber ich verkaufe den Karren jetzt aus politischen Gründen und wegen Familiennachwuchs..
Pros: gute Batterielebensdauer
Mileage: 62000 km
Model 3 mit 79 kWh Akku hier. Zustand: 85% Kapazität. Laufleistung: 150.847 km, Stand heute. Erstbesitzer seit 04/2020. Bin Berufspendler. Lade hauptsächlich mit 11kW. Auf Langstrecken Supercharger mit 250kW in der Spitze. Verhältnis 80/20. Schnellladen schadet den Akkus (es ist nicht "der Akku", es sind viele Zellen, geclustert in Bricks, mit jeweils eigenem BMS) gar nicht großartig mehr, als laden mit geringeren Leistungen. Per Definition gilt schnellladen auch erst ab 2x Kapazität in Ladeleistung (2h), bei meinem Akku also erst ab 158kW. "Der Akku" geht also nicht gleich komplett kaputt, wie man es von Handy kennt. Man kann auch einzelne Bricks tauschen.
Pros: gute Kapazität, lange Lebensdauer
Mileage: 150847 km
Yes. '19 M3 SR+. Mobile tech came, better battery than the original. Didn't want to get scr\\*wed with a shutdown.
Pros: better battery
Cons: shutdown
I also just had a new battery installed by BMW, $600 for the honor.
Pros: new battery installed
Cons: expensive installation
Vehicle:
BMW
BMW i3… loved that little toaster but 80 mile range wasn’t cutting it anymore. I still enjoyed running errands and zipping through parking lots.
Pros: loved the car
Cons: limited range
Vehicle:
BMW
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.
Cons: battery out of spec
Mileage: 200000 km
My first Tesla battery died after 1.5 years of gentle use and the replacement they gave me is currently at 84%. Just like my 2 year old iPhone. Batteries degrade much more than these studies suggest.
Cons: battery died prematurely, replacement degraded quickly
