Battery Varta or Exide

Varta working for 6 years

Varta are the best ones I ever used. I use them in my car key too and its the only battery that lasts years instead of 2 months at most.

I still use a factory Audi (Varta) from 2014, so 11 years, but I'm not sure it will survive the first -15-25C this winter.

My VARTA on the e46 compact lasted 8years

Varta make some good shit.

Got a new Exide battery at our expense outside. Car is fine ever since then.

Just replaced battery as EV had stopped working, and the battery dealer said it was. Good battery for hyrbids (Exide X40DPMF)

Walmart EverStart (make sure it's at least a 2 year warranty. The economy power ones are junk) or you can get Exide batteries at Home Depot for pretty cheap.

Friends don't let friends use Exide batteries. They literally will rot out your battery cables.

However if you bought an Exide battery, 100% it's your issue: I have had three batteries replaced under warranty on my BMW until I said "basta" and bought a Yuasa out of pocket. The amount of weird issues those junky batteries caused was beyond belief.
