Battery Deka 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

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
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

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

UPdate - new battery and bluetooth 12v monitor installed last Monday night, all good since then including one day with 40 miles of driving and recharging in weather well below freezing (16 to 28 F), but I happen to be mostly driving other cars the rest of the time since.
FYI, altho I ordered from Remy, the sticker on the battery I received says [Deka Intimidator EHP](https://remybattery.com/batteries/brand/deka-intimidator-batteries.html?srsltid=AfmBOorxsFi7eoMbizQPDMsF1q-32WuvMxLPyiLSgftX8ExWmqHWSfq4). IDK if there's any functional difference - it seems to have the exact same terminal connections as the OEM BMW battery it replaced.
Also FWIW, despite no indicator on the shipping box for 'this side up' and it clearly getting Ace-Ventura'd around by FedEx, it did not leak or show any signs of damage inside the shipping box. It was well padded with foam made to fit the battery and fill the entire shipping box. So far I'm happy and the car seems to be too.
Pros: happy with new battery

OEM for Harley. I've replaced several with an average lifespan of 5 yrs at 20%+ cheaper than Harley branded
Pros: long lifespan, cheaper
I had 8 years on original battery on 2017 750i. I replaced it. It was barely holding 12V. Few functions were not working like stop/start and such.
Pros: 8 years longevity
Cons: barely holding 12V, functions not working
Vehicle:
BMW
I’m not satisfied with the range (70 miles) or the charging speed (max 19.2 kW via J-1772, taking 4 to 13 hours to charge) of the BMW batteries in my Lion Type C electric school bus.
Cons: poor range, slow charging speed
