Battery Tesla or Energizer

If I could easily repurpose the cells in my 140k mile Model 3 into home storage for my solar I would rather do that than sell the car. 3% degradation the car itself needed more work than a replacement battery ever would have cost.

I typically use what is shipped with the packaging. Most of my red dots are trijicon and they ship with energizer so I will continue to use it. I feel the companies do their own testing trail and error with battery life and usage at all power levels under all temperatures.

Energizer. Better QC than Duracell imho.

Duracell lasted 18 months on my RMR 3.25 Type 2 on auto setting, Energizer lasted 23 months on same setting!

Having ran both Duracell procell, and Energizer lithiums in RMR's, the energizers last 3+ years. I've gotten 2-2.5 years out of Duracell.

Funny enough I also have an 18 Elantra and had my battery replaced recently from Costco. What I got was a:

- H6-AGM

- 760/120/70 cold crank amps/reserve capacity/amp hours respectively

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

As promised: 2019 M3 LR , 55k miles/88514km, latest Tesla Battery Health Test 83%

A bit worse than expected.

Yes. Mine was from 2020 and quit without warning March of this year. Contrary to what some people have said, the car won\u2019t always warn you that the battery is weak.

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.
