Battery Tesla or Exide

I got a `EA530 exide 079te` for my leaf just over a year ago and so far it's still working perfect.

Exide are great batteries and are a tier 1 supplier with Yuasa, Bosch, Varta.

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

IMHO, Exide works well till the last second and then dies off without any symptoms. Amaron shows alot of symptoms like extra cranking and lights dim for interior and dash lights when it's nearing its demise. Hence I moved to amaron. So should you.

After reading all replies and knowing the price of the dealers option, I took my chance with a Exide battery AGM 12-23, it was a perfect fit.

I don't think they are good at inverters, but I have used their battery for ups which lasted 4 years, now i am using the second one which completed one year

2018 M3P with 54K and it is right at 7%

My 2019 M3 with 50K miles says 288 miles today (310 original) but it has been far lower at times (255 miles) and bounces around.

Exide Battery (demolished)

battery life is astonishingly unpredictable. I drove 20 miles, but lost ~35 miles of range. Not driving crazy, either. Everything else is decent, but can't help but feel like it's a time bomb.
