I carry about 20 batteries with me when I go out. I made a double sided label good and bad to fit inside the cases for quick reference. The locks on the suitcases could work better, no failures yet but I don't see them lasting long. I hope I'm wrong. But considering how I use them and how much I need them I will buy more even if I need a mod to keep them closed. Price wise you can't expect Pelikan quality from them and there aren't many options. So for my purposes I need it and I'm glad I bought it. My recent kayaking expedition was a lot less frustrating and more organized.
