Know Your Batteries’ True Capacity!

Ideal for makers, recyclers, and tech enthusiasts, the CH-3.0 eliminates guesswork by providing scientific metrics to compare battery performance.

📌 Note: For best results, fully charge batteries before testing and avoid exceeding 3A discharge on small cells (e.g., 18650).
