Battery Exide 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
Its an AGM battery, once it gets depleted heavily this happen. Just replace it. The factory batteries are made by exide or varta so just seek out a same spec replacement from those brands
Pros: Replace depleted AGM battery
I use Deka sealed batteries so less offgassing messing up terminals.
Pros: less offgassing
Cons: messing up terminals
Got a new Exide battery at our expense outside. Car is fine ever since then.
Pros: car fine since then
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
Deka batteries. I’ve turned wrenches for twenty years and they’re the only ones that still consistently test far above their rated capacity when new. I have one that’s 7 years old and just installed one in my other rig last year.
Pros: above rated capacity, long lifespan
Just replaced battery as EV had stopped working, and the battery dealer said it was. Good battery for hyrbids (Exide X40DPMF)
Pros: Good for hybrids
Part number: X40DPMF
Ära Exide akusid osta, need hunnik sitta. Varta akud on okeid. Kui autol on start-stop süsteem siis peab kindlasti vaatama kas autol on EFB või AGM tüüpi aku ja vahetama sama tüüpi aku vastu.
Pros: Varta akud on okeid
Cons: Exide akud hunnik sitta
its surely a dead battery, the fuckall exide batteries that they give are dogshit. had the same issue some days ago, thankfully the bike was covered under warranty.
im honestly thinking of changing the battery to a better one.
Pros: covered under warranty
Cons: dead battery, dogshit
Same shit keeps happening with my N250 for some reason, the starter relay just does the "tk tk" sound but bike doesnt start, Service centre said the factory battery was faulty, so bought a new Exide battery and everything was perfect for 1.5 months.
Pros: perfect for 1.5 months
Cons: battery faulty after months
