Owner reviews for battery

I'm running a 320 amp alternator with AGM odyssey battery so far no issues

I've run Optima red tops for years and never had a problem.

Ended up finding a red top in the back of the store at Advanced (34R with 800CCA). If you go with Optima know that it takes some modification with the wiring. I needed to remove a cable tie and relocate one of the positive leads. Outback started right up and is running great.

I’ve had good luck with the VW OEM Varta batteries.

I have seen some test results on ID3 after 100000 km and still everything is quite good on the car. Battery is not damaged like on a cellphone if that is your worry.

Tesla on nmc battery drops around 10% after 8 or 10 years (can't remember exactly) from what I read. But lfp battery is inherently able to have longer life span and charge cycles. On top of inherently having ability to be safer / less explodey.

For context, I have a first generation Tesla Model S - 2014. It has 215,000-ish miles on it. The battery capacity has gone down by about 10-12%. It still runs and drives like a dream. It's on the original battery.

Happened to me too, the first day of usage. Weirdly, when i restarted, it dropped from 100 to 92. Then another time from 80 something to 60 something. It was probably some battery reading issue, cuz the overall runtime of 10hrs of screentime was not affected.

my Optima Red Top failed after 2 years & 7 months. this is the last time I'll buy one.

I just replaced the Mopar original provided battery 2 weeks ago. This was after I was able to jump it and get it to the dealership. \nThen 2 days ago I tried to remote start it\u2026 no dice.\nGot in had acc but no start, no cranking just one click. \nTried to jump again and no lock. The brake locked up and couldn\u2019t be pushed more than a quarter inch.
