Battery Energizer or Duracell

We’ve always had luck with Duracell in our cars.

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.

The replacement battery I bought was a Duracell from Sam’s Club. Fit and worked fine.

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!

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.

FWIW…. I’ve had 3 Duracell batteries and all have died within 3 years of manufacture date, and they have a 2yr warranty.

I'm not putting a Duracell in my car, they can't even make a double A that doesn't leak within the year.

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.
