Battery Energizer or OEM BMW
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
Vehicle:
BMW
I typically use what is shipped with the packaging. Most of my red dots are trijicon and they ship with energizer so I will continue to use it. I feel the companies do their own testing trail and error with battery life and usage at all power levels under all temperatures.
Pros: good battery life
Energizer. Better QC than Duracell imho.
Pros: better quality control
Duracell lasted 18 months on my RMR 3.25 Type 2 on auto setting, Energizer lasted 23 months on same setting!
Pros: Energizer lasts longer
Cons: Duracell shorter lifespan
Having ran both Duracell procell, and Energizer lithiums in RMR's, the energizers last 3+ years. I've gotten 2-2.5 years out of Duracell.
Pros: Energizer lasts longer
Cons: Duracell shorter lifespan
I’ve had my iX for 2.5 years and have logged 122k miles. I haven’t noticed any degradation in battery capacity. Just the normal summer/winter fluctuations (live in Midwest).
Pros: no battery degradation
Vehicle:
BMW
Mileage: 196339 km
Funny enough I also have an 18 Elantra and had my battery replaced recently from Costco. What I got was a:
- H6-AGM
- 760/120/70 cold crank amps/reserve capacity/amp hours respectively
Vehicle:
Hyundai Elantra
Part number: 1346545
I had one with the battery that lasted just under 12 years.... Old original BMW batteries are built different! Especially if the car is driven regularly.
Pros: lasted 12 years, built different
BMW i3… loved that little toaster but 80 mile range wasn’t cutting it anymore. I still enjoyed running errands and zipping through parking lots.
Pros: loved the car
Cons: limited range
Vehicle:
BMW
530e with a little over 20,000 miles shows 10 miles electric range on a nice summer day. It used to show 15 when new. BMW said that the drop was not warranty worthy.
Cons: reduced electric range, not warranty worthy
Vehicle:
BMW
Mileage: 32187 km
