I've been using PKNOVA's 100-pack AA batteries for a few months now, and here's the real deal. First off, the price is unbeatable for bulk buyers like me who go through batteries like candy during holiday seasons.

These batteries shine in low-drain devices. My wireless keyboard and TV remotes? Flawless performance for months. But I noticed they struggle a bit in high-drain gadgets like digital cameras - they drain faster than premium brands.

The temperature claim holds up! Left some in my freezing garage (-2°F) and they still worked in my outdoor thermometer. That's impressive for budget batteries.

Had one dud in my first pack, but their customer service sent a replacement immediately. Most work fine though - currently powering 12+ devices in my home without issues.

Would I recommend? Yes, but with caveats. Great for everyday devices, not ideal for power-hungry electronics. At this price point, they're worth trying despite some inconsistency.
