Why Choose the CH-3.0 Tester?

🔹 Professional Accuracy – Reliable data for battery grading/repurposing. 🔹 User-Friendly UI – Intuitive menus + visual discharge curves. 🔹 Compact & Portable – Fits in toolkits for on-the-go testing. 🔹 Cost-Effective – Cheaper than industrial testers with similar features.

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).
