I put a Japan made energizer 2300mh storage at least for 8 monts, charged before storage and surprise, they make my flash work very quick even at maximum power, recycling flash time is even better than manufacturer specs.
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.
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
Recently i was able to acquire some Japanese Energizer 2300 and 800mAh AA and AAA batteries...from my experience with the Energizers so far they are much much better then any other NiMH battery I've ever used including the Chinese Panasonic NiMH batteries.
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.
Energizer is a shit battery. I had to put an Energizer one out of no options and that barely lasted a year.
This is the worst battery i tried, Enegizer lasted less than a year, maybe around 6 months only and it started dying.
