Let me tell you, as someone who's constantly swapping out dead batteries in remotes, flashlights, and kids' toys, discovering ACDelco's 200-count AAA pack felt like finding gold. That reclosable packaging? Genius. No more loose batteries rolling around my junk drawer.

The real test came when I used these in my high-drain Xbox controller. They held up surprisingly well - I got about 25 hours of gameplay before needing replacements. Not quite Energizer-level longevity, but at this price point? Absolutely acceptable.

Where these truly shine is in low-drain devices. My kitchen clock has been running on the same pair for 8 months now with no signs of slowing down. The claimed 10-year shelf life gives me peace of mind for emergency preparedness too.

Two minor gripes: the stainless steel coating does make them slightly slippery when handling, and while they claim to be leak-proof, I did have one package arrive with a slightly swollen battery (though it still worked fine).

For bulk battery needs - whether it's stocking up for emergencies or powering an entire wedding's worth of candles like one reviewer mentioned - this pack delivers exceptional value without compromising too much on performance.
