MAXIMIZE STORAGE WITH 160+ CAPACITY: Eliminate cluttered junk drawers with this high-capacity battery organizer storage case. The custom pre-cut foam perfectly secures 148 standard batteries (66 AA, 48 AAA, 8 C, 6 D, 8 9V, and 12 button cells), while the built-in interior mesh pocket provides extra room to store dozens of additional loose batteries or small charging cables. It centralizes your entire household's power supply in one neat, accessible place. | PREVENT SHORT CIRCUITS & MOISTURE DAMAGE: Protect your home and your batteries from dangerous hazards. Unlike brittle clear plastic boxes that easily shatter when dropped, our battery holder is crafted from splash-proof, anti-fall HQ EVA material. The individual foam slots keep every battery firmly separated, protecting them from moisture and completely eliminating the risk of short circuits, friction, or messy battery leaks. | REMOVABLE BT-168 TESTER INCLUDED: Stop wasting money throwing away perfectly good batteries. This battery storage box comes with a fully removable, easy-to-use BT-168 digital checker that requires no batteries to run. It instantly and accurately tests the power levels of your 1.5V (AA, AAA, C, D) and 9V batteries, allowing you to easily distinguish which batteries to keep and which to recycle. | ULTIMATE PORTABILITY FOR ON-THE-GO POWER: Always be prepared for power outages, photography shoots, or outdoor adventures. Designed for ultimate convenience, this lightweight battery carrying case features a reinforced top handle and a smooth 360-degree double zipper. Its compact profile makes it easy to slide into a backpack, tool bag, drawer, or RV cabinet, serving as your reliable portable power companion. | SECURELY HOLDS RECHARGEABLE & BUTTON CELLS: Say goodbye to losing tiny, expensive coin cells. The precision-cut foam compartments are engineered to snugly fit a wide variety of battery types, seamlessly accommodating slightly thicker rechargeable batteries and securely locking in small button cells (like CR2032/LR44). Keep all your essential batteries strictly organized in one premium battery container. (Please note: Batteries are NOT included).
