Some storage containers for batteries are small and designed to fit only four to eight batteries at a time, and they are designated by their size to accommodate different singular types of batteries. Some units are also designed to fit more than one type of battery in the case.
Proper storage conditions for batteries typically depend on the type of battery and the chemicals found in its core. For best results, users should keep batteries in temperature conditions that do not exceed 60 degrees Fahrenheit. Over time, the electrolyte seal may dry out and reduce the efficiency of the battery, and proper storage helps slow this process.
