Battery OEM Mazda or OEM BMW
The OEM battery is AGM. If it was an OEM battery it wouldn't be lead acid, at least here in the US. Not sure what you're talking about. I installed mine three years ago and have had no issues despite winters that range from below 0 to summers that reach 100. Fahrenheit obviously.
Pros: no issues for three years
Vehicle:
BMW
OEM batteries are made from fairy dust. I still have my original one in my E92, made in 2007. Def recommend getting an OEM battery.
Pros: excellent longevity, original quality
Vehicle:
BMW
BMW here. No issues.

Tried them all at some point and whatever BMW OE does to those they last 2-3X longer. I literally just replaced a 14 year old battery last September….fuckin insane longevity with the OEM ones.
Pros: long lifespan, excellent durability

Stock OEM Mazda CX5 battery is weak AF. My 2019 battery died in Jan 2024 after coming back from Disney trip that lasted 7 days. Got one from Costco. Higher CCA for less than OEM from Mazda. Installed myself.
Pros: Higher CCA, less expensive
Cons: Stock battery weak

My 2014 CX-5 eats batteries and always has since i bought it brand new. I usually have to replace 1x a year\u2026 and I know it\u2019s coming about 45 days in advance because my bluetooth and USB chargers will suddenly stop working and that\u2019s how i know oh my battery will die soon!
Cons: battery dies yearly
Vehicle:

I have the same problem with my Mazada 3. Changed the battery while still under warranty and still does it. I don't leave anything pluggeded in and it still dies overnight. I purchased a battery tender and have to hook it up every night or get a boost in the morning.
Cons: dies overnight
