They will never let you down
I have a few different flashlights that take these batteries and when the power goes out and everything gets dark, Energizer is only battery my family trust. They have never let us down even after sitting idle in a drawer for weeks sometimes.

Make sure they are lithium AA batteries (Ultimate Lithium) and not rechargeable ones.
Excellent longevity, especially in high-drain devices. Energizer markets them as their longest-lasting AA batteries. Energizer +1 ❄️☀️ They operate in extreme temperatures, ranging from approximately -40°F to 140°F (-40°C to 60°C). Energizer 💧 They feature a leak-resistant design, and Energizer states they are leak-proof under standard use. Energizer 🪶 They are approximately 33% lighter than traditional alkaline batteries.

Best quality for the value!
Super reliable, one less thing I have to worry about going bad on me or rust. More affordable is not always the best value when you have to purchase multiple more of the same item.

Shelf life, durability
My most used battery type. I bought them YEARS ago ask you could see by the packaging and still have one package closed. Performance is very good, no discharge or drain as of yet, I’ve left them inside my analog cameras and outside and they’re perfect. Perfect size too

Reliability and durability
These are the only batteries that I rely on for my home alarm. My motion detectors and my door and window detectors have these and I will never change because they’re reliable and they last forever.

No guarantee your pickup will be fast!
Batteries are batteries. I got exactly what I ordered. HOWEVER when I went to pick it up I had to wait 1/2 hour in line while they had some freakin' beeny baby special or something that was taking up all of the Pick-up/Return counters! That's the last time I'll try that "time saving device!"

Long blasting
Batteries last a long time for the level bolt. Need to change it maybe every six months. Would recommend. Easy to fi D at stores and not too expensive for a single.
