Let me start by saying, these Energizer MAX AA batteries are a game-changer! I've been using them in everything from my kid's toys to the smoke alarms around the house, and they just keep going and going (pun intended).

The 20-pack is such a smart buy - I used to constantly run out of batteries mid-project, but now I always have spares ready. What really impressed me was how well they work in high-drain devices. My wireless gaming mouse that used to eat through batteries now lasts weeks longer.

I did notice one small drawback though - while they do last significantly longer than basic alkalines, in extremely demanding devices like digital cameras, you might still wish for even more longevity. But for the price? Absolutely worth it.

The leak-resistant feature gives me peace of mind too. After finding corroded batteries in an old remote (from another brand), I appreciate that Energizer stands behind their 2-year leakage protection promise.

Pro tip: These are perfect for emergency preparedness kits since they hold power up to 10 years in storage. I've stashed some in my hurricane supplies and feel confident they'll work when needed.

Final verdict? If you want reliable power that won't let you down (and won't break the bank), these Energizers are your best bet. My household will definitely be buying these again!
