Let me start by saying, this organizer is a game-changer. No more rummaging through a junk drawer full of loose batteries, wondering if that AA is fresh or dead. The Aptbyte box holds EVERYTHING—AA, AAA, 9V, even those weird button batteries for calculators. I fit 78 AAs and still had room for my 18650s (yes, both sides!).

The plastic slots are genius—no flimsy foam tearing like my old case. Each battery clicks into place like it was made for it. I dropped the closed box once (oops), and not a single battery escaped thanks to those four sturdy latches. The clear lid is my favorite part—I can do a quick ‘battery inventory’ before grocery runs without even opening it.

That built-in tester? Lifesaver. Last week I tested 20 AAAs in under a minute to prep for my kid’s toy marathon. Pro tip: The backside horizontal slots perfectly fit my bulky D-cells for camping lanterns, while the front keeps daily-use batteries upright and grab-and-go ready.

Is it perfect? Almost. I wish it had dedicated CR2032 slots (I improvised by stacking them in the sponge section). But when my electrician saw it, he immediately asked for the link—that’s when you know you’ve found a winner.
