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.
Energizer. Better QC than Duracell imho.
Duracell lasted 18 months on my RMR 3.25 Type 2 on auto setting, Energizer lasted 23 months on same setting!
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.
If willing to pay for a Optima yellow top, I suggest you get an Odyssey battery instead. It's a much better battery for about the same price.
I finally spent the money on an odyssey extreme on my 7.3 along with an aftermarket starter and battery cables. Absolute game changer in the wintertime. I could leave it out in the cold for a week and it would start faster than the old battery setup would in the summer.
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
I had same issue with energizer batteries both lasted exactly 14 months. Luckily battery came with18 months warranty so in total they lasted 28 months.
This is the worst battery i tried, Enegizer lasted less than a year, maybe around 6 months only and it started dying.
It's not only Energizer, its also whatever cheap brand I have. Might be a law, I think.
I do hate them, either cutting your fingers or have the cell fly out like a chemical saucer.
