Portable Battery Organizer Storage Case - No Lid Snap, Built-in Tester, Wall-Mounted Design Holds 110 Batteries (AAA, AA, 9V, C, D) - Perfect for Home, Office & Emergency Kits (Black)

Pros: 1) keeps several types of batteries together so you can see at a glance what you have. 2) holds D,C , AA, AAA, & 9 volt. NOT watch or small round batteries. CONS: 1) Only holds 8 D cell, and they fit tight so you have to be careful pulling out as they stick. 2) CANNOT mount unless you angle on a ledge. 3) Most importantly it doesn't have a cover so again you can't mount or some batteries will fall out. But...it's just fine to place flat in my office drawer which is where I keep it. If you want to mount, get one with a cover.I really appreciate how organized my batteries are now, much better than the previous organizer bin I was using that didn't quite fit all battery types properly. I also really appreciate having a simple battery tester that snaps to the case. However, the quality feels fairly cheap. The entire product is made of plastic, and relatively thin, which keeps its own weight down. But when loaded with batteries, it obviously gets pretty heavy. If you drop this guy, I would expect a corner to break or side to crack. The battery tester also feels pretty cheap. In fact, the first one that I received worked to test exactly one battery, then the needle didn't budge for any subsequent battery. But the exchange I received has been working just fine for a couple months now.The only real thing I would've preferred with this is a lid that seals over the batteries, as I noticed that quite a few of the batteries I relocated from my previous bin (which had a lid) were rusted to different degrees. I'm sure this would happen even if there was a lid, but I feel there would be less oxidation with less open air exchange. It would also help to prevent any batteries from spilling out if accidentally dropped or tipped.This is a great storage for batteries. I hoke how you can test without removing the tester. The only issue is the batteries are a little loose in the racks. This is only an issue if hanging. My solution for this was to put a shim under the bottom edge of the rack.It was fine for the intended use, however, I wish it had less D & C sizes storage and more AA and AAA sizes.The tester is easy to use and convenient. I would have liked more storage for the C and D batteries.Good qualityI would recommend this to anyoneOnly way can be used without batteries coming out is in a drawer. They state that you can wall mount. Not very good for wall mounting. Battery tester very cheap.This is a great invention. Keeps batteries organized.
