Let me tell you, these Kenstar AAA batteries are the unsung heroes of my gadget drawer. I've been using them in everything from my TV remote to my kid's noisy toys, and they just keep going. The price per battery is ridiculously low, making this 36-pack a no-brainer for households like mine that burn through batteries.

The leakproof design gives me peace of mind - no more finding corroded batteries in my favorite devices. I especially appreciate this when using them in my digital thermometer and wireless mouse where battery leaks could mean expensive replacements.

Now about that 10-year shelf life claim - like some reviewers noticed, mine arrived with about 4 years left before expiration. Honestly? That's still plenty for how quickly we use them. They perform exactly like any standard alkaline battery should - no surprises, just reliable power.

Where these really shine is in low-drain devices. In my kitchen clock? Lasted over a year. In the flashlight? Throws a strong beam without flickering. They might not be the absolute longest-lasting for high-drain devices like gaming controllers, but at this price point, you can afford to swap them more frequently.

The environmental aspect matters too - no mercury or cadmium means I don't feel guilty using so many. Pro tip: Buy these when they're on sale (which is often) and you'll never run out of household power again!
