Let me start by saying, these KODAK AA batteries are a game-changer! I've been using them in everything from my Xbox controller to my kid's noisy toys, and they just keep going. Unlike some other brands that die after a few hours of heavy use, these bad boys last for days—even with my marathon gaming sessions.

The 60-pack is an absolute steal. I used to burn through rechargeables like crazy (and let's be honest, waiting for them to charge is a pain). With these, I'm changing batteries way less often. One user mentioned playing Xbox for 4-6 hours daily and still going strong on day 4—I can confirm similar performance!

What really impressed me was finding out they have a 10-year shelf life. I stashed some in my emergency kit without worrying they'll be dead when I need them. Plus, they're leak-proof and eco-friendly (no mercury, cadmium or lead), which gives me peace of mind when using them in expensive devices.

They work brilliantly in high-drain devices like controllers and walkie-talkies, but also shine in low-drain items like clocks and bike lights. The Christmas lantern test another reviewer mentioned? Spot on—these kept my holiday decorations glowing all season.

The only minor note is that some batches might have older manufacturing dates (like the 2016 production mentioned), but with that decade-long shelf life, it's really not an issue. For the price and performance, these are hands-down my new go-to batteries.
