Here’s an item that exemplifies the virtues of simplicity and utility: the PowerPax Battery Caddy, manufactured in St. Charles, IL. It’s like an egg carton for batteries. Loose batteries are a potential acid-leaking hazard, and hard to keep track of. The Battery Caddy solves this problem with a molded plastic unit that has two rows of cylindrical openings to hold batteries in a range of sizes, plus a hook on one end so you can hang them up in a convenient place. PowerPax offers several models, including one that glows in the dark. Visit www.powerpax.net for more information.
