Battery Tesla or Deka
You can get an Deka AUX18L from batterymart.com for $159 shipped to your door. Deka is the OE manufacturer of the BMW battery for the i3. My original battery lasted 7 years, it’s a no-brainer.
Pros: lasted 7 years
Vehicle:
BMW
Part number: AUX18L
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
Pros: essentially same range as new
Cons: lower than advertised range
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.
Pros: high longevity, good performance
Cons: 21% degradation
Mileage: 370148 km
I use Deka sealed batteries so less offgassing messing up terminals.
Pros: less offgassing
Cons: messing up terminals
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
I only use deka on my service rig. Usa made quality. Though listed at 540 CCA, MY Midtronics tester shows they output 650 - 750 CCA.. I easily get 7 years use in the field with these.
Pros: USA made quality, high CCA output, long lifespan
Owned a model Y for 2 years and 65k miles (9% battery degradation for those wondering). It got extremely boring and I was tired of the constant nagging from the car.
Cons: extremely boring, constant nagging
Mileage: 65000 km
Warranty: side repeater, spoiler, battery (at 82k)
Pros: warranty covered
Mileage: 82000 km
I do worry about the battery and 3 years in my big battery died and thankfully I was in my garage. I shudder to think if it had happened on a freeway! Tesla gave me a new battery but I still think about it often.
Cons: battery died, lingering worry
Knowing what I know now I would. My 2021 was built in July 2021 and about a year ago my car bricked on me and wouldn\u2019t start. I had zero warning ahead of time.
Pros: mobile service dame
Cons: car bricked, zero warning
