I have a Pelican 1510 that I keep my camera stuff in as well as many other pelicans of different sizes; however, I don’t keep any batteries inside the cases…especially any that are Lithium Ion. I also keep a big packet of desiccant in the cases to prevent mold and fungus from spreading inside if left for long periods of time, unattended. These two items work together perfectly to preserve my gear. I suspect I could leave this gear in the cases for 100 years and come back to find all of it (except batteries) in 100% pristine condition.
