Review on Fireproof Battery Organizer Storage Case: Waterproof & Explosionproof Safe Bag Fits 210+ Batteries - With Tester BT-168, Carrying Container Bag For AA AAA C D 9V Lithium 3V Holders by Michael Harden

I really geeked out on this. I've had my batteries "organized" in a shoe box, and it's worked out. okay. But this is just awesome! I was literally so excited to get this and pop all the batteries into their designated slots. Ones that I assumed wouldn't have spots (like watch batteries, etc.) did, and the pocket in the lid holds my re-chargers and the battery tester. Switch to rechargeables, people! The tester really helps, since you can check that your rechargeables are fully charged up. It's also handy for figuring out if a battery-operated thing is broken or if it's the batteries. You don't have to keep changing out the batteries and guessing.
