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.

Pros: quick flash, better specs

Cons: weak chinese made

I had a 2004 Scion xb back in the day that was made in Japan. Had to get rid of it after the engine developed excessive oil consumption. Had a hell of a battery in it. Panasonic brand.

Pros: hell of a battery

Yeah, the oem Panasonic battery is easy to kill. I replaced mine (2022 Turbo) with an AGM type. Most all batteries are made by Johnson Controls, under different names. The cheapest price I found was $179 with a 4 year warranty at Walmart. Everstart Platinum group 35. Was a 10 min job to remove and replace. They can even test your old one. The agm type is in the deep cycle family, it can be discharged quite a bit without any issues, the stock battery (flooded acid type) is easy to damage.

Pros: AGM type, deep cycle

Cons: OEM battery easy to kill

Vehicle: Mazda

Part number: GROUP 35

My 2019 Mazda 3 died on me randomly a couple months ago. The dealership ran a test on it and it came out fine. I changed it anyway as it was a stock 5 year old battery. It’s been fine since, even in the -20°C temps where I am.

Pros: fine even in cold

Vehicle: Mazda 3

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
