Protect Your Power Battery Case (Cylindrical)

The Protect Your Power Slimline Battery Cases are Canadian-made, high-impact storage organizers designed to securely transport and protect individual batteries from short-circuiting, rattling, and weather damage. Built specifically for outdoor enthusiasts, tech professionals, and emergency preparedness, they substitute fragile hard-plastic cases with rugged, flexible protection. [1, 2, 3, 4, 5]

• High-Impact TPU Construction: Molded from tough, flexible Thermoplastic Polyurethane (TPU) that acts like a soft, durable rubber shell. Unlike standard plastic cases, it will not crack, shatter, or break when dropped. [2, 3, 6]
• Secure Micro-Bevel Lid: Features an integrated lip and latch closure that tightly snaps shut. This prevents the top from accidentally slipping off inside a backpack, purse, or toolbox. [2, 3, 5]
• Terminal & Short-Circuit Safety: Keeps both battery terminals completely covered and separated. This prevents them from coming into contact with other metals, eliminating short-circuit or discharge risks. [2, 3, 7]
• Anti-Rattle Snug Fit: Custom engineered for specific battery form factors to minimize movement and sound. Cases include small foam inserts where necessary to provide a silent, rattle-free carry. [5, 8, 9, 10]
• Charge Status Tracking: Designed so you can insert live batteries right-side up, and spent or dead batteries upside down, allowing easy tracking of power levels. [3, 11, 12, 13]
• Weather and Leak Resistance: Protects batteries from damp environments, dust, and rain, while safely containing any potential chemical leaks from ruining external gear. [2, 14, 15, 16]

The lineup covers specific options tailored to individual sizes, rather than generic multi-size compromises. They are typically sold directly in 2-packs on the Protect Your Power Store: [6, 8, 17, 18, 19]

According to the official Protect Your Power FAQ, TPU material should only be washed using mild soap and warm water. Always use a soft cloth, avoid abrasive brushes, let the case air dry completely, and never clean the material with harsh chemicals or solvents like acetone and alcohol. [8]
